sorry.

I just test this problem im my computer, found:
1 computer name not allow "."
2 if you want resolve your problem, you should cofigure below files and append some content:
10.21.106.1(your IP address) asdf.mydomainanme
so let computer recongnize your domain name.

please configure your IIS.
your web root name might be "asdf", and a virtual directory might be "asptest", so you can access your page via "http://asdf/asptest/xxx.asp".

if you renname these item, you can via your page via "http://asdf.mydomainname/asptest/xxx.asp"

i can accept your answer as correct answer

1：外文原文 Struts——an open-source MVC implementation This article introduces Struts, a Model-View-Controller implementation that uses servlets and JavaServer Pages (JSP) technology. Struts can help you control change in your Web project and promote specialization. Even if you never implement a system with Struts, you may get some ideas for your future servlets and JSP page implementation. Introduction Kids in grade school put HTML pages on the Internet. However, there is a monumental difference between a grade school page and a professionally developed Web site. The page designer (or HTML developer) must understand colors, the customer, product flow, page layout, browser compatibility, image creation, JavaScript, and more. Putting a great looking site together takes a lot of work, and most Java developers are more interested in creating a great looking object interface than a user interface. JavaServer Pages (JSP) technology provides the glue between the page designer and the Java developer. If you have worked on a large-scale Web application, you understand the term change. Model-View-Controller (MVC) is a design pattern put together to help control change. MVC decouples interface from business logic and data. Struts is an MVC implementation that uses Servlets 2.2 and JSP 1.1 tags, from the J2EE specifications, as part of the implementation. You may never implement a system with Struts, but looking at Struts may give you some ideas on your future Servlets and JSP implementations. Model-View-Controller (MVC) JSP tags solved only part of our problem. We still have issues with validation, flow control, and updating the state of the application. This is where MVC comes to the rescue. MVC helps resolve some of the issues with the single module approach by dividing the problem into three categories: • Model The model contains the core of the application's functionality. The model encapsulates the state of the application. Sometimes the only functionality it contains is state. It knows nothing about the view or controller. • View The view provides the presentation of the model. It is the look of the application. The view can access the model getters, but it has no knowledge of the setters. In addition, it knows nothing about the controller. The view should be notified when changes to the model occur. • Controller The controller reacts to the user input. It creates and sets the model. MVC Model 2 The Web brought some unique challenges to software developers, most notably the stateless connection between the client and the server. This stateless behavior made it difficult for the model to notify the view of changes. On the Web, the browser has to re-query the server to discover modification to the state of the application. Another noticeable change is that the view uses different technology for implementation than the model or controller. Of course, we could use Java (or PERL, C/C++ or what ever) code to generate HTML. There are several disadvantages to that approach: • Java programmers should develop services, not HTML. • Changes to layout would require changes to code. • Customers of the service should be able to create pages to meet their specific needs. • The page designer isn't able to have direct involvement in page development. • HTML embedded into code is ugly. For the Web, the classical form of MVC needed to change. Figure 4 displays the Web adaptation of MVC, also commonly known as MVC Model 2 or MVC 2. The ActionServlet class Do you remember the days of function mappings? You would map some input event to a pointer to a function. If you where slick, you would place the configuration information into a file and load the file at run time. Function pointer arrays were the good old days of structured programming in C. Life is better now that we have Java technology, XML, J2EE, and all that. The Struts Controller is a servlet that maps events (an event generally being an HTTP post) to classes. And guess what -- the Controller uses a configuration file so you don_t have to hard-code the values. Life changes, but stays the same. ActionServlet is the Command part of the MVC implementation and is the core of the Framework. ActionServlet (Command) creates and uses Action, an ActionForm, and ActionForward. As mentioned earlier, the struts-config.xml file configures the Command. During the creation of the Web project, Action and ActionForm are extended to solve the specific problem space. The file struts-config.xml instructs ActionServlet on how to use the extended classes. There are several advantages to this approach: • The entire logical flow of the application is in a hierarchical text file. This makes it easier to view and understand, especially with large applications. • The page designer does not have to wade through Java code to understand the flow of the application. • The Java developer does not need to recompile code when making flow changes. Command functionality can be added by extending ActionServlet. The ActionForm class ActionForm maintains the session state for the Web application. ActionForm is an abstract class that is sub-classed for each input form model. When I say input form model, I am saying ActionForm represents a general concept of data that is set or updated by a HTML form. For instance, you may have a UserActionForm that is set by an HTML Form. The Struts framework will: • Check to see if a UserActionForm exists; if not, it will create an instance of the class. • Struts will set the state of the UserActionForm using corresponding fields from the HttpServletRequest. No more dreadful request.getParameter() calls. For instance, the Struts framework will take fname from request stream and call UserActionForm.setFname(). • The Struts framework updates the state of the UserActionForm before passing it to the business wrapper UserAction. • Before passing it to the Action class, Struts will also conduct form state validation by calling the validation() method on UserActionForm. Note: This is not always wise to do. There might be ways of using UserActionForm in other pages or business objects, where the validation might be different. Validation of the state might be better in the UserAction class. • The UserActionForm can be maintained at a session level. Notes: • The struts-config.xml file controls which HTML form request maps to which ActionForm. • Multiple requests can be mapped UserActionForm. • UserActionForm can be mapped over multiple pages for things such as wizards. The Action class The Action class is a wrapper around the business logic. The purpose of Action class is to translate the HttpServletRequest to the business logic. To use Action, subclass and overwrite the process() method. The ActionServlet (Command) passes the parameterized classes to ActionForm using the perform() method. Again, no more dreadful request.getParameter() calls. By the time the event gets here, the input form data (or HTML form data) has already been translated out of the request stream and into an ActionForm class. Struts, an MVC 2 implementation Struts is a set of cooperating classes, servlets, and JSP tags that make up a reusable MVC 2 design. This definition implies that Struts is a framework, rather than a library, but Struts also contains an extensive tag library and utility classes that work independently of the framework. Figure 5 displays an overview of Struts. Struts overview • Client browser An HTTP request from the client browser creates an event. The Web container will respond with an HTTP response. • Controller The Controller receives the request from the browser, and makes the decision where to send the request. With Struts, the Controller is a command design pattern implemented as a servlet. The struts-config.xml file configures the Controller. • Business logic The business logic updates the state of the model and helps control the flow of the application. With Struts this is done with an Action class as a thin wrapper to the actual business logic. • Model state The model represents the state of the application. The business objects update the application state. ActionForm bean represents the Model state at a session or request level, and not at a persistent level. The JSP file reads information from the ActionForm bean using JSP tags. • View The view is simply a JSP file. There is no flow logic, no business logic, and no model information -- just tags. Tags are one of the things that make Struts unique compared to other frameworks like Velocity. Note: "Think thin" when extending the Action class. The Action class should control the flow and not the logic of the application. By placing the business logic in a separate package or EJB, we allow flexibility and reuse. Another way of thinking about Action class is as the Adapter design pattern. The purpose of the Action is to "Convert the interface of a class into another interface the clients expect. Adapter lets classes work together that couldn_t otherwise because of incompatibility interface" (from Design Patterns - Elements of Reusable OO Software by Gof). The client in this instance is the ActionServlet that knows nothing about our specific business class interface. Therefore, Struts provides a business interface it does understand, Action. By extending the Action, we make our business interface compatible with Struts business interface. (An interesting observation is that Action is a class and not an interface. Action started as an interface and changed into a class over time. Nothing's perfect.) The Error classes The UML diagram also included ActionError and ActionErrors. ActionError encapsulates an individual error message. ActionErrors is a container of ActionError classes that the View can access using tags. ActionErrors is Struts way of keeping up with a list of errors. The ActionMapping class An incoming event is normally in the form of an HTTP request, which the servlet Container turns into an HttpServletRequest. The Controller looks at the incoming event and dispatches the request to an Action class. The struts-config.xml determines what Action class the Controller calls. The struts-config.xml configuration information is translated into a set of ActionMapping, which are put into container of ActionMappings. (If you have not noticed it, classes that end with s are containers) The ActionMapping contains the knowledge of how a specific event maps to specific Actions. The ActionServlet (Command) passes the ActionMapping to the Action class via the perform() method. This allows Action to access the information to control flow. ActionMappings ActionMappings is a collection of ActionMapping objects. Struts pros • Use of JSP tag mechanism The tag feature promotes reusable code and abstracts Java code from the JSP file. This feature allows nice integration into JSP-based development tools that allow authoring with tags. • Tag library Why re-invent the wheel, or a tag library? If you cannot find something you need in the library, contribute. In addition, Struts provides a starting point if you are learning JSP tag technology. • Open source You have all the advantages of open source, such as being able to see the code and having everyone else using the library reviewing the code. Many eyes make for great code review. • Sample MVC implementation Struts offers some insight if you want to create your own MVC implementation. • Manage the problem space Divide and conquer is a nice way of solving the problem and making the problem manageable. Of course, the sword cuts both ways. The problem is more complex and needs more management. Struts cons • Youth Struts development is still in preliminary form. They are working toward releasing a version 1.0, but as with any 1.0 version, it does not provide all the bells and whistles. • Change The framework is undergoing a rapid amount of change. A great deal of change has occurred between Struts 0.5 and 1.0. You may want to download the most current Struts nightly distributions, to avoid deprecated methods. In the last 6 months, I have seen the Struts library grow from 90K to over 270K. I had to modify my examples several times because of changes in Struts, and I am not going to guarantee my examples will work with the version of Struts you download. • Correct level of abstraction Does Struts provide the correct level of abstraction? What is the proper level of abstraction for the page designer? That is the $64K question. Should we allow a page designer access to Java code in page development? Some frameworks like Velocity say no, and provide yet another language to learn for Web development. There is some validity to limiting Java code access in UI development. Most importantly, give a page designer a little bit of Java, and he will use a lot of Java. I saw this happen all the time in Microsoft ASP development. In ASP development, you were supposed to create COM objects and then write a little ASP script to glue it all together. Instead, the ASP developers would go crazy with ASP script. I would hear "Why wait for a COM developer to create it when I can program it directly with VBScript?" Struts helps limit the amount of Java code required in a JSP file via tag libraries. One such library is the Logic Tag, which manages conditional generation of output, but this does not prevent the UI developer from going nuts with Java code. Whatever type of framework you decide to use, you should understand the environment in which you are deploying and maintaining the framework. Of course, this task is easier said than done. • Limited scope Struts is a Web-based MVC solution that is meant be implemented with HTML, JSP files, and servlets. • J2EE application support Struts requires a servlet container that supports JSP 1.1 and Servlet 2.2 specifications. This alone will not solve all your install issues, unless you are using Tomcat 3.2. I have had a great deal of problems installing the library with Netscape iPlanet 6.0, which is supposedly the first J2EE-compliant application server. I recommend visiting the Struts User Mailing List archive (see Resources) when you run into problems. • Complexity Separating the problem into parts introduces complexity. There is no question that some education will have to go on to understand Struts. With the constant changes occurring, this can be frustrating at times. Welcome to the Web. • Where is... I could point out other issues, for instance, where are the client side validations, adaptable workflow, and dynamic strategy pattern for the controller? However, at this point, it is too easy to be a critic, and some of the issues are insignificant, or are reasonable for a 1.0 release. The way the Struts team goes at it, Struts might have these features by the time you read this article, or soon after. Future of Struts Things change rapidly in this new age of software development. In less than 5 years, I have seen things go from cgi/perl, to ISAPI/NSAPI, to ASP with VB, and now Java and J2EE. Sun is working hard to adapt changes to the JSP/servlet architecture, just as they have in the past with the Java language and API. You can obtain drafts of the new JSP 1.2 and Servlet 2.3 specifications from the Sun Web site. Additionally, a standard tag library for JSP files is appearing. 2:外文资料翻译译文 Struts——MVC 的一种开放源码实现本文介绍 Struts，它是使用 servlet 和 JavaServer Pages 技术的一种 Model-View-Controller 实现。Struts 可帮助您控制 Web 项目中的变化并提高专业化水平。尽管您可能永远不会用 Struts 实现一个系统，但您可以将其中的一些思想用于您以后的 servlet 和 JSP 网页的实现中。简介小学生也可以在因特网上发布 HTML 网页。但是，小学生的网页和专业开发的网站有质的区别。网页设计人员（或者 HTML 开发人员）必须理解颜色、用户、生产流程、网页布局、浏览器兼容性、图像创建和 JavaScript 等等。设计漂亮的网站需要做大量的工作，大多数 Java 开发人员更注重创建优美的对象接口，而不是用户界面。JavaServer Pages (JSP) 技术为网页设计人员和 Java 开发人员提供了一种联系钮带。如果您开发过大型 Web 应用程序，您就理解变化这个词的含义。“模型-视图-控制器”(MVC) 就是用来帮助您控制变化的一种设计模式。MVC 减弱了业务逻辑接口和数据接口之间的耦合。Struts 是一种 MVC 实现，它将 Servlet 2.2 和 JSP 1.1 标记（属于 J2EE 规范）用作实现的一部分。尽管您可能永远不会用 Struts 实现一个系统，但了解一下 Struts 或许使您能将其中的一些思想用于您以后的 Servlet 的 JSP 实现中。模型-视图-控制器 (MVC) JSP 标记只解决了部分问题。我们还得处理验证、流程控制和更新应用程序的状态等问题。这正是 MVC 发挥作用的地方。MVC 通过将问题分为三个类别来帮助解决单一模块方法所遇到的某些问题： • Model（模型）模型包含应用程序的核心功能。模型封装了应用程序的状态。有时它包含的唯一功能就是状态。它对视图或控制器一无所知。 • View（视图）视图提供模型的表示。它是应用程序的外观。视图可以访问模型的读方法，但不能访问写方法。此外，它对控制器一无所知。当更改模型时，视图应得到通知。 • Controller（控制器）控制器对用户的输入作出反应。它创建并设置模型。 MVC Model 2 Web 向软件开发人员提出了一些特有的挑战，最明显的就是客户机和服务器的无状态连接。这种无状态行为使得模型很难将更改通知视图。在 Web 上，为了发现对应用程序状态的修改，浏览器必须重新查询服务器。另一个重大变化是实现视图所用的技术与实现模型或控制器的技术不同。当然，我们可以使用 Java（或者 PERL、C/C++ 或别的语言）代码生成 HTML。这种方法有几个缺点： • Java 程序员应该开发服务，而不是 HTML。 • 更改布局时需要更改代码。 • 服务的用户应该能够创建网页来满足它们的特定需要。 • 网页设计人员不能直接参与网页开发。 • 嵌在代码中的 HTML 很难看。对于 Web，需要修改标准的 MVC 形式。图 4 显示了 MVC 的 Web 改写版，通常也称为 MVC Model 2 或 MVC 2。 Struts，MVC 2 的一种实现 Struts 是一组相互协作的类、servlet 和 JSP 标记，它们组成一个可重用的 MVC 2 设计。这个定义表示 Struts 是一个框架，而不是一个库，但 Struts 也包含了丰富的标记库和独立于该框架工作的实用程序类。图 5 显示了 Struts 的一个概览。 Struts 概览 • Client browser（客户浏览器）来自客户浏览器的每个 HTTP 请求创建一个事件。Web 容器将用一个 HTTP 响应作出响应。 • Controller（控制器）控制器接收来自浏览器的请求，并决定将这个请求发往何处。就 Struts 而言，控制器是以 servlet 实现的一个命令设计模式。 struts-config.xml 文件配置控制器。 • 业务逻辑业务逻辑更新模型的状态，并帮助控制应用程序的流程。就 Struts 而言，这是通过作为实际业务逻辑“瘦”包装的 Action 类完成的。 • Model（模型）的状态模型表示应用程序的状态。业务对象更新应用程序的状态。ActionForm bean 在会话级或请求级表示模型的状态，而不是在持久级。JSP 文件使用 JSP 标记读取来自 ActionForm bean 的信息。 • View（视图）视图就是一个 JSP 文件。其中没有流程逻辑，没有业务逻辑，也没有模型信息 -- 只有标记。标记是使 Struts 有别于其他框架（如 Velocity）的因素之一。详细分析 Struts 图 6 显示的是 org.apache.struts.action 包的一个最简 UML 图。图 6 显示了 ActionServlet (Controller)、 ActionForm (Form State) 和 Action (Model Wrapper) 之间的最简关系。 ActionServlet 类您还记得函数映射的日子吗？在那时，您会将某些输入事件映射到一个函数指针上。如果您对此比较熟悉，您会将配置信息放入一个文件，并在运行时加载这个文件。函数指针数组曾经是用 C 语言进行结构化编程的很好方法。现在好多了，我们有了 Java 技术、XML、J2EE，等等。Struts 的控制器是将事件（事件通常是 HTTP post）映射到类的一个 servlet。正如您所料 -- 控制器使用配置文件以使您不必对这些值进行硬编码。时代变了，但方法依旧。 ActionServlet 是该 MVC 实现的 Command 部分，它是这一框架的核心。 ActionServlet (Command) 创建并使用 Action 、 ActionForm 和 ActionForward 。如前所述， struts-config.xml 文件配置该 Command。在创建 Web 项目时，您将扩展 Action 和 ActionForm 来解决特定的问题。文件 struts-config.xml 指示 ActionServlet 如何使用这些扩展的类。这种方法有几个优点： • 应用程序的整个逻辑流程都存储在一个分层的文本文件中。这使得人们更容易查看和理解它，尤其是对于大型应用程序而言。 • 网页设计人员不必费力地阅读 Java 代码来理解应用程序的流程。 • Java 开发人员也不必在更改流程以后重新编译代码。可以通过扩展 ActionServlet 来添加 Command 功能。 ActionForm 类 ActionForm 维护 Web 应用程序的会话状态。 ActionForm 是一个抽象类，必须为每个输入表单模型创建该类的子类。当我说输入表单模型时,是指 ActionForm 表示的是由 HTML 表单设置或更新的一般意义上的数据。例如，您可能有一个由 HTML 表单设置的 UserActionForm 。Struts 框架将执行以下操作： • 检查 UserActionForm 是否存在；如果不存在，它将创建该类的一个实例。 • Struts 将使用 HttpServletRequest 中相应的域设置 UserActionForm 的状态。没有太多讨厌的 request.getParameter() 调用。例如，Struts 框架将从请求流中提取 fname ，并调用 UserActionForm.setFname() 。 • Struts 框架在将 UserActionForm 传递给业务包装 UserAction 之前将更新它的状态。 • 在将它传递给 Action 类之前，Struts 还会对 UserActionForm 调用 validation() 方法进行表单状态验证。注：这并不总是明智之举。别的网页或业务可能使用 UserActionForm ，在这些地方，验证可能有所不同。在 UserAction 类中进行状态验证可能更好。 • 可在会话级维护 UserActionForm 。注： • struts-config.xml 文件控制 HTML 表单请求与 ActionForm 之间的映射关系。 • 可将多个请求映射到 UserActionForm 。 • UserActionForm 可跨多页进行映射，以执行诸如向导之类的操作。 Action 类 Action 类是业务逻辑的一个包装。 Action 类的用途是将 HttpServletRequest 转换为业务逻辑。要使用 Action ，请创建它的子类并覆盖 process() 方法。 ActionServlet (Command) 使用 perform() 方法将参数化的类传递给 ActionForm 。仍然没有太多讨厌的 request.getParameter() 调用。当事件进展到这一步时，输入表单数据（或 HTML 表单数据）已被从请求流中提取出来并转移到 ActionForm 类中。注：扩展 Action 类时请注意简洁。 Action 类应该控制应用程序的流程，而不应该控制应用程序的逻辑。通过将业务逻辑放在单独的包或 EJB 中，我们就可以提供更大的灵活性和可重用性。考虑 Action 类的另一种方式是 Adapter 设计模式。 Action 的用途是“将类的接口转换为客户机所需的另一个接口。Adapter 使类能够协同工作，如果没有 Adapter，则这些类会因为不兼容的接口而无法协同工作。”（摘自 Gof 所著的 Design Patterns - Elements of Reusable OO Software ）。本例中的客户机是 ActionServlet ，它对我们的具体业务类接口一无所知。因此，Struts 提供了它能够理解的一个业务接口，即 Action 。通过扩展 Action ，我们使得我们的业务接口与 Struts 业务接口保持兼容。（一个有趣的发现是， Action 是类而不是接口）。 Action 开始为一个接口，后来却变成了一个类。真是金无足赤。） ActionMapping 类输入事件通常是在 HTTP 请求表单中发生的，servlet 容器将 HTTP 请求转换为 HttpServletRequest 。控制器查看输入事件并将请求分派给某个 Action 类。 struts-config.xml 确定 Controller 调用哪个 Action 类。 struts-config.xml 配置信息被转换为一组 ActionMapping ，而后者又被放入 ActionMappings 容器中。（您可能尚未注意到这一点，以 s结尾的类就是容器） ActionMapping 包含有关特定事件如何映射到特定 Action 的信息。 ActionServlet (Command) 通过 perform() 方法将 ActionMapping 传递给 Action 类。这样就使 Action 可访问用于控制流程的信息。 ActionMappings ActionMappings 是 ActionMapping 对象的一个集合。 Struts 的优点 • JSP 标记机制的使用标记特性从 JSP 文件获得可重用代码和抽象 Java 代码。这个特性能很好地集成到基于 JSP 的开发工具中，这些工具允许用标记编写代码。 • 标记库为什么要另发明一种轮子，或标记库呢？如果您在库中找不到您所要的标记，那就自己定义吧。此外，如果您正在学习 JSP 标记技术，则 Struts 为您提供了一个起点。 • 开放源码您可以获得开放源码的全部优点，比如可以查看代码并让使用库的每个人检查代码。许多人都可以进行很好的代码检查。 • MVC 实现样例如果您希望创建您自己的 MVC 实现，则 Struts 可增加您的见识。 • 管理问题空间分治是解决问题并使问题可管理的极好方法。当然，这是一把双刃剑。问题越来越复杂，并且需要越来越多的管理。 Struts 的缺点 • 仍处于发展初期 Struts 开发仍处于初级阶段。他们正在向着发行版本 1.0 而努力，但与任何 1.0 版本一样，它不可能尽善尽美。 • 仍在变化中这个框架仍在快速变化。Struts 1.0 与 Struts 0.5 相比变化极大。为了避免使用不赞成使用的方法，您可能隔一天就需要下载最新的 Struts。在过去的 6 个月中，我目睹 Struts 库从 90K 增大到 270K 以上。由于 Struts 中的变化，我不得不数次修改我的示例，但我不保证我的示例能与您下载的 Struts 协同工作。 • 正确的抽象级别 Struts 是否提供了正确的抽象级别？对于网页设计人员而言，什么是正确的抽象级别呢？这是一个用 $64K 的文字才能解释清楚的问题。在开发网页的过程中，我们是否应该让网页设计人员访问 Java 代码？某些框架（如 Velocity）说不应该，但它提供了另一种 Web 开发语言让我们学习。在 UI 开发中限制访问 Java 有一定的合理性。最重要的是，如果让网页设计人员使用一点 Java，他将使用大量的 Java。在 Microsoft ASP 的开发中，我总是看到这样的情况。在 ASP 开发中，您应该创建 COM 对象，然后编写少量的 ASP 脚本将这些 COM 对象联系起来。但是，ASP 开发人员会疯狂地使用 ASP 脚本。我会听到这样的话，“既然我可以用 VBScript 直接编写 COM 对象，为什么还要等 COM 开发人员来创建它呢？”通过使用标记库，Struts 有助于限制 JSP 文件中所需的 Java 代码的数量。Logic Tag 就是这样的一种库，它对有条件地生成输出进行管理，但这并不能阻止 UI 开发人员对 Java 代码的狂热。无论您决定使用哪种类型的框架，您都应该了解您要在其中部署和维护该框架的环境。当然，这项任务真是说起来容易做起来难。 • 有限的适用范围 Struts 是一种基于 Web 的 MVC 解决方案，所以必须用 HTML、JSP 文件和 servlet 来实现它。 • J2EE 应用程序支持 Struts 需要支持 JSP 1.1 和 Servlet 2.2 规范的 servlet 容器。仅凭这一点远不能解决您的全部安装问题，除非使用 Tomcat 3.2。我用 Netscape iPlanet 6.0 安装这个库时遇到一大堆问题，按理说它是第一种符合 J2EE 的应用程序服务器。我建议您在遇到问题时访问 Struts 用户邮件列表的归档资料。 • 复杂性在将问题分为几个部分的同时也引入了复杂性。毫无疑问，要理解 Struts 必须接受一定的培训。随着变化的不断加入，这有时会令人很沮丧。欢迎访问本网站。 Struts 的前景在这个软件开发的新时代，一切都变得很快。在不到 5 年的时间内，我已经目睹了从 cgi/perl 到 ISAPI/NSAPI、再到使用 VB 的 ASP、一直到现在的 Java 和 J2EE 的变迁。Sun 正在尽力将新的变化反映到 JSP/servlet 体系结构中，正如他们对 Java 语言和 API 所作的更改一样。您可以从 Sun 的网站获得新的 JSP 1.2 和 Servlet 2.3 规范的草案。此外，一个标准 JSP 标记库即将出现。 3：外文出处 [1]Malcolm Davis.

Version Control repository: --------------------------- svn://svn.overbyte.be/ics or http://svn.overbyte.be:8443/svn/ics (Usercode = ics, password = ics) Installation: ------------- ICS V8 has been designed for Embarcadero Delphi 2009 and up, and C++ Builder 2009 and up, but is fully compatible with Borland Delphi 7 and CodeGear 2006 and 2007. Embarcadero RAD Studio includes Delphi and C++ Builder. http://www.embarcadero.com/ With Delphi XE2 and later, VCL 64-bit Windows targets are supported for Delphi only. Currently FireMonkey is partly supported for Delphi only (there are still a few non-ported components). ICS for Mac OSX is currently experimental. The zip file has sub-directories in it. You must use the WinZip "Use folder names" option to restore this directory tree or you will have problems because the files would not be in their proper subdirectories. Please note most of these directories are differently named to ICS V7 and earlier, to ease support of multiple versions of Delphi and platforms, and to ease location of similar sample projects. Please don't install V8 over an existing V7 installation, it will be a mess of old and new. This is the new V8 sub-directory layout: .\ Info directory .\Install Component packages project groups for all versions .\Packages (was Delphi\Vc32) Delphi (7 and up) and C++Builder (2006 and up) packages projects .\Source (was Delphi\Vc32) ICS Delphi source code built into packages .\Source\Include (was Delphi\Vc32) .inc files (including OverbyteIcsDefs.inc) .\Source\Extras (was Delphi\Vc32) Extra source code not built into packages .\Source\zobj125 (was Delphi\Vc32) ZLIB C OBJ include files .\Lib Unit output directories for all package builds, subdirectories | for 2007+ will be created on building the packages \$(Config) Release / Debug | \$(Platform) Win32 / Win64 / OSX32 | \ D7..XE8, 10 Seattle includes .dcu and .dfm files for Delphi and .obj and .hpp files for C++ Builder .\Samples Delphi Win32/Win64 common source for all demos .\Samples\delphi\BroswerDemo Delphi Win32/Win64 Web Browser sample application (all Delphi versions) .\Samples\delphi\BroswerDemo\Resources Resource file, web pages and movie linked into browser demo .\Samples\delphi\FtpDemos Delphi Win32/Win64 FTP sample applications (all Delphi versions) .\Samples\delphi\MailNewsDemos Delphi Win32/Win64 SMTP, POP3, NNTP sample applications (all Delphi versions) .\Samples\delphi\MiscDemos Delphi Win32/Win64 Miscellaneous applications (all Delphi versions) .\Samples\delphi\OtherDemos Delphi Win32/Win64 DNS, Ping, SNMP, Syslog sample applications (all Delphi versions) .\Samples\delphi\PlatformDemos Delphi FireMonkey and cross-platform samples (Delphi XE2+) .\Samples\delphi\SocketDemos Delphi Win32/Win64 Socket sample applications (all Delphi versions) .\Samples\delphi\sslinternet Delphi Win32/Win64 SSL-enabled sample applications (all Delphi versions) .\Samples\delphi\WebDemos Delphi Win32/Win64 HTTP sample applications (all Delphi versions) .\Samples\delphi\WebDemos\WebAppServerData Directory for WebAppServ demo data files .\Samples\delphi\WebDemos\WebServData Directory for WebServ demo data files .\Samples\cpp\internet C++Builder sample applications .\Samples\cpp\internet\cb2006 C++Builder 2006 projects .\Samples\cpp\internet\cb2007 C++Builder 2007 projects .\Samples\cpp\internet\cb2009 C++Builder 2009 projects .\Samples\cpp\internet\cb2010 C++Builder 2010 projects .\Samples\cpp\internet\cbXE C++Builder XE projects .\Samples\cpp\internet\cbXE2 C++Builder XE2 projects UPGRADING and REINSTALLING Uninstall an existing ICS package (Menu | Component | Install Packages, select the component package and click Remove). Rename the old ICS directory and unzip to a new or empty directory, remove the old path from the library path and add either the new .\Source directory to the library path under Tools | Options |... or the appropriate .\Lib subdirectory according to version, ie .\Lib\Debug\Win32\D2007 for Delphi 2007. The latter has the advantage that the ICS source code won't be recompiled whenever your project is build. Also under Tools | Options |... add the new .\Source directory to the Browsing path. All DELPHI and C++ BUILDER VERSIONS/WIN32 Always upgrade your compiler with the latest update available from Embarcadero. Always update your system with http://windowsupdate.microsoft.com SSL or not SSL? By default the SSL code is compiled into the run-time package and additional SSL- enabled components are installed. In order to not compile the SSL code into the run-time package and to not install the SSL-Enabled components you need to remove the conditional define USE_SSL from both the run-time and design-time package. However if you do not build your applications with run-time packages it is recommended to build the packages with default settings. The SSL code will the be compiled into your applications depending on whether the conditional define USE_SSL is set in the project options or not (this requires having the .\Source directory in either in the library path or in projects Search path). Actual use of SSL in your applications also requires the OpenSSL files LIBEAY32.DLL and SSLEAY32.DLL being available somewhere in the path. Note different DLLs are needed for Win32 and Win64 applications. The ICS distribution includes the latest Win32 OpenSSL files in the .\OpenSSL-Win32 directory and the two main DLLs duplicated in .\Samples\delphi\sslinternet. Other OpenSSL files, including older and Win64, may be downloaded from: http://wiki.overbyte.be/wiki/index.php/ICS_Download INSTALLATION USING THE INSTALL PROJECT GROUPS For each Delphi and C++ Builder version one project group is provided in directory .\Install: Delphi 7 : D7Install.bpg Delphi 2006 : D2006Install.bdsgroup Delphi 2007 : D2007Install.groupproj Delphi 2009 : D2009Install.groupproj Delphi 2010 : D2010Install.groupproj Delphi XE : DXeInstall.groupproj Delphi XE2 : DXe2Install.groupproj // VCL only, no FireMonkey components Delphi XE2 : DXe2InstallVclFmx.groupproj // Both VCL and FireMonkey components Delphi XE3 : DXe3Install.groupproj // VCL only, no FireMonkey components Delphi XE3 : DXe3InstallVclFmx.groupproj // Both VCL and FireMonkey components Delphi XE4 : DXe4Install.groupproj // VCL only, no FireMonkey components Delphi XE4 : DXe4InstallVclFmx.groupproj // Both VCL and FireMonkey components Delphi XE5 : DXe5Install.groupproj // VCL only, no FireMonkey components Delphi XE5 : DXe5InstallVclFmx.groupproj // Both VCL and FireMonkey components Delphi XE6 : DXe6Install.groupproj // VCL only, no FireMonkey components Delphi XE6 : DXe6InstallVclFmx.groupproj // Both VCL and FireMonkey components Delphi XE7 : DXe7Install.groupproj // VCL only, no FireMonkey components Delphi XE7 : DXe7InstallVclFmx.groupproj // Both VCL and FireMonkey components Delphi XE8 : DXe8Install.groupproj // VCL only, no FireMonkey components Delphi XE8 : DXe8InstallVclFmx.groupproj // Both VCL and FireMonkey components Delphi 10 Seattle : D10SInstall.groupproj // VCL only, no FireMonkey components Delphi 10 Seattle : D10SInstallVclFmx.groupproj // Both VCL and FireMonkey components C++ Builder 2006 : CB2006Install.bdsgroup C++ Builder 2007 : CB2007Install.groupproj C++ Builder 2009 : CB2009Install.groupproj C++ Builder 2010 : CB2010Install.groupproj C++ Builder XE : CBXeInstall.groupproj C++ Builder XE2 : CBXe2Install.groupproj // VCL only no FireMonkey components C++ Builder XE2 : CBXe2InstallVclFmx.groupproj // Both VCL and FireMonkey components C++ Builder XE3 : CBXe3InstallVclFmx.groupproj // Both VCL and FireMonkey components 1 - Do a File/Open Project, navigate to the Install directory, select the correct file and open it. The project manager view should now display two package projects, one run-time and one design-time package. The run-time package name contains the "Run" suffix. The design-time package name contains the "Design" suffix. 2 - Select and Build the run-time package (do not install). 3 - Select and Install the design-time package. After a few seconds, you should have a dialog box telling you the package has been installed with a bunch of new components registered in the Tool Palette under "Overbyte ICS" and "Overbyte ICS SSL". Then do a "Save All" and a "Close All". 4 - One package is installed, called 'Overbyte ICS Design-Time Package for Delphi xxx'. 5 - Various directories under .\Samples\delphi\ include samples that illustrate use of all the ICS components, see later. FIREMONKEY CROSS PLATFORM PACKAGES: 1 - For XE2 and later, DXe?Install (where ? is the version) installs VCL components only, while DXe?InstallVclFmx also installs FireMonkey cross platform components (three run time packages). In order to use this feature first uninstall the old design-time package. 2 = Build all three run-time packages for all available platforms (32-bit and 64-bit Windows and Mac OS X) in the order they are listed in project manager. 3 - Next build and install the three design-time packages in the order they are listed in project manager. 4 - Three packages are installed, called: 'Overbyte ICS Common Design-Time Package for Delphi xxx' 'Overbyte ICS FMX Design-Time Package for Delphi xxx' 'Overbyte ICS VCL Design-Time Package for Delphi xxx' Note that the new packaging is still beta/alpha, both package names and included units might change in a future beta drop. The old VCL packages are still there however they do no longer support FireMonkey and of course only one set of packages can be installed in the IDE at the same time, if you want both VCL and FMX install DXe2InstallVclFmx.groupproj only. Currently the XE2 package cache is buggy and should be disabled by adding the -nocache parameter. 5 - The .\Samples\delphi\PlatformDemos\ folder contains FireMonkey sample projects that may all be built with FireMonkey for Mac OS X (and Windows). ALTERNATE INSTALLATION USING THE PACKAGE PROJECT FILES: For each Delphi and C++ Builder version two package project files exist in the .\Packages directory. One run-time and one design-time package project file. The run-time file name contains the "Run" suffix. The design-time file name contains the "Design" suffix. PACKAGE PROJECT FILE NAMES - VCL: Delphi 7 : OverbyteIcsD7Run.dpk, OverbyteIcsD7Design.dpk Delphi 2006 : OverbyteIcsD2006Run.bdsproj, OverbyteIcsD2006Design.bdsproj Delphi 2007 : OverbyteIcsD2007Run.dproj, OverbyteIcsD2007Design.dproj Delphi 2009 : OverbyteIcsD2009Run.dproj, OverbyteIcsD2009Design.dproj Delphi 2010 : OverbyteIcsD2010Run.dproj, OverbyteIcsD2010Design.dproj Delphi XE : OverbyteIcsDXeRun.dproj, OverbyteIcsDXeDesign.dproj Delphi XE2 : OverbyteIcsDXe2Run.dproj, OverbyteIcsDXe2Design.dproj Delphi XE3 : OverbyteIcsDXe3Run.dproj, OverbyteIcsDXe3Design.dproj Delphi XE4 : OverbyteIcsDXe4Run.dproj, OverbyteIcsDXe4Design.dproj Delphi XE5 : OverbyteIcsDXe5Run.dproj, OverbyteIcsDXe5Design.dproj Delphi XE6 : OverbyteIcsDXe6Run.dproj, OverbyteIcsDXe6Design.dproj Delphi XE7 : OverbyteIcsDXe7Run.dproj, OverbyteIcsDXe7Design.dproj Delphi XE8 : OverbyteIcsDXe8Run.dproj, OverbyteIcsDXe8Design.dproj Delphi 10 Seattle : OverbyteIcsD10SRun.dproj, OverbyteIcsD10SDesign.dproj C++ Builder 2006 : OverbyteIcsCB2006Run.bdsproj, OverbyteIcsCB2006Design.bdsproj C++ Builder 2007 : OverbyteIcsCB2007Run.cbproj, OverbyteIcsCB2007Design.cbproj C++ Builder 2009 : OverbyteIcsCB2009Run.cbproj, OverbyteIcsCB2009Design.cbproj C++ Builder 2010 : OverbyteIcsCB2010Run.cbproj, OverbyteIcsCB2010Design.cbproj C++ Builder XE : OverbyteIcsCBXeRun.cbproj, OverbyteIcsCBXeDesign.cbproj C++ Builder XE2 : OverbyteIcsCBXe2Run.cbproj, OverbyteIcsCBXe2Design.cbproj C++ Builder XE3 : OverbyteIcsCBXe3Run.cbproj, OverbyteIcsCBXe3Design.cbproj PACKAGE PROJECT FILE NAMES - FireMonkey and VCL: Delphi XE2 FMX/VCL : IcsCommonDXe2Run.dproj, IcsCommonDXe2Design.dproj Delphi XE2 VCL : IcsVclDXe2Run.dproj, IcsVclDXe2Design.dproj Delphi XE2 FMX : IcsFmxDXe2Run.dproj, IcsFmxDXe2Design.dproj Delphi XE3 FMX/VCL : IcsCommonDXe3Run.dproj, IcsCommonDXe3Design.dproj Delphi XE3 VCL : IcsVclDXe3Run.dproj, IcsVclDXe3Design.dproj Delphi XE3 FMX : IcsFmxDXe3Run.dproj, IcsFmxDXe3Design.dproj Delphi XE4 FMX/VCL : IcsCommonDXe4Run.dproj, IcsCommonDXe4Design.dproj Delphi XE4 VCL : IcsVclDXe4Run.dproj, IcsVclDXe4Design.dproj Delphi XE4 FMX : IcsFmxDXe4Run.dproj, IcsFmxDXe4Design.dproj Delphi XE5 FMX/VCL : IcsCommonDXe5Run.dproj, IcsCommonDXe5Design.dproj Delphi XE5 VCL : IcsVclDXe5Run.dproj, IcsVclDXe5Design.dproj Delphi XE5 FMX : IcsFmxDXe5Run.dproj, IcsFmxDXe5Design.dproj Delphi XE6 FMX/VCL : IcsCommonDXe6Run.dproj, IcsCommonDXe6Design.dproj Delphi XE6 VCL : IcsVclDXe6Run.dproj, IcsVclDXe6Design.dproj Delphi XE6 FMX : IcsFmxDXe6Run.dproj, IcsFmxDXe6Design.dproj Delphi XE7 FMX/VCL : IcsCommonDXe7Run.dproj, IcsCommonDXe7Design.dproj Delphi XE7 VCL : IcsVclDXe7Run.dproj, IcsVclDXe7Design.dproj Delphi XE7 FMX : IcsFmxDXe7Run.dproj, IcsFmxDXe7Design.dproj Delphi XE8 FMX/VCL : IcsCommonDXe8Run.dproj, IcsCommonDXe8Design.dproj Delphi XE8 VCL : IcsVclDXe8Run.dproj, IcsVclDXe8Design.dproj Delphi XE8 FMX : IcsFmxDXe8Run.dproj, IcsFmxDXe8Design.dproj Delphi 10 Seattle FMX/VCL: IcsCommonD10SRun.dproj, IcsCommonD10SDesign.dproj Delphi 10 Seattle VCL : IcsVclD10SRun.dproj, IcsVclD10SDesign.dproj Delphi 10 Seattle FMX : IcsFmxD10SRun.dproj, IcsFmxD10SDesign.dproj C++ Builder XE2 FMX/VCL : IcsCommonCBXe2Run.dproj, IcsCommonDXe2Design.dproj C++ Builder XE2 VCL : IcsVclCBXe2Run.dproj, IcsVclCBXe2Design.dproj C++ Builder XE2 FMX : IcsFmxCBXe2Run.dproj, IcsFmxCBXe2Design.dproj C++ Builder XE3 FMX/VCL : IcsCommonCBXe3Run.dproj, IcsCommonDXe3Design.dproj C++ Builder XE3 VCL : IcsVclCBXe3Run.dproj, IcsVclCBXe3Design.dproj C++ Builder XE3 FMX : IcsFmxCBXe3Run.dproj, IcsFmxCBXe3Design.dproj 1 - Open and Build the run-time package project (do not install!). 2 - Open and Install the design-time package project. (Do a File/Open Project, browse to the .\Packages directory. Select the correct file and open it. Then in the project manager view, right-click on the package, then click on either the Build or Install button.) 3 - For Delphi XE2 and later, a 64-bit run-time package can be built by changing the package target platform to 64-bit Windows. This has the same name as the 32-bit package, so a different package output directory needs to be specified in Tools / Options / Delphi Options for 64-bit Windows. After a few seconds, you should have a dialog box telling you the package has been installed with a bunch of new components registered in the Tool Palette under "Overbyte ICS" and "Overbyte ICS SSL". Then do a "Save All" and a "Close All". DELPHI 2006/WIN32, 2007/WIN32, 2009/WIN32, 2010/WIN32, XE/WIN32: Having installed the package, verify that the appropriate Win32 Library Path (Tools / Options / Delphi Options / Library - Win32 / Library Path) has been added, .\Lib subdirectory according to version, ie .\Lib\Debug\Win32\D2007 for Delphi 2007. If not, add it manually. It is not mandatory to add .\Lib to the global Delphi path, but it will be much easier for you because otherwise you'll have to add it to each project. DELPHI XE2/WIN32, XE3/WIN32, XE4/WIN32, XE5/WIN32, XE6/WIN32, XE7/WIN32, XE8/WIN32, 10 Seattle/WIN32, XE2/WIN64, XE3/WIN64, XE4/WIN64, XE5/WIN64, XE6/WIN64, XE7/WIN64, XE8/WIN64, 10 Seattle/WIN64: Similar to above, but the Library path is specified separately for 32-bit and 64-bit Windows Platforms. DELPHI 7: Add VC32 directory path to your library path (Tools menu / Environment Options / Library / Library Path. Add .\Lib\Debug\Win32\D7 path at the end of the existing path). SAMPLE DELPHI PROJECTS Once the package is installed, you may open the sample projects. The samples are split into several directories according to protocols, most with a project group that can be opened in all versions of Delphi. .\Samples\delphi\BroswerDemo .\Samples\delphi\FtpDemos\FtpDemos.bpg .\Samples\delphi\MailNewsDemos\MailNewsDemos.bpg .\Samples\delphi\MiscDemos\MiscDemos.bpg .\Samples\delphi\OtherDemos\OtherDemos.bpg .\Samples\delphi\PlatformDemos\XSamples.groupproj .\Samples\delphi\SocketDemos\SocketDemos.bpg .\Samples\delphi\sslinternet\SslDemos.bpg .\Samples\delphi\WebDemos\WebDemos.bpg Full details of the sample projects are shown later in this document. You might get some dialog box telling you that resource files are missing (they may not have been included in the zip file to save space) and are recreated by Delphi. It is OK. Any other error message is a problem you should fix. After all resource files have been recreated, you should see in the project manager a group of projects. To compile all samples in the group at once, do Project / Build all projects. This may take a few minutes. Note 1: Delphi may run out of memory if you ask to compile all projects at once. If you have not enough RAM, then compile each project individually. Note 2: Delphi has warnings which triggers a lot of messages for 100% OK code. You can turn those warnings off in the project/ options / Compiler messages and deselecting: "Deprecated symbol", "Platform symbol", "unsafe type", "unsafe code", "unsafe typecast". Those are intended for .NET and Linux portability. You can safely ignore them if you run windows. For you facility, I included a utility SetProjectOptions (source code, you must compile it) in the internet directory. This utility will update project options to disable the warnings. Once the components are all installed, you may open the sample projects each one after the other and compile them. For each project, do file/open and select the dpr file in the internet directory. Then Project/Build All. C++ BUILDER 2006, 2007, 2009, 2010, XE, XE2, XE3: Follow the installation procedure described for Delphi 2006. Just change the project group and package name: use CB2006, CBXe, etc, see above. You can't have Delphi 2006 and CBuilder 2006 packages installed at the same time in the IDE. So when switching from one to the other, be sure to remove the one you don't need. Building the FireMonkey CBXE2InstallVclFmx C++ packages for OSX may trigger an ILINK32 error, this is a bug in C++ Builder reported as QC #103668 the Win32 packages should build without errors. Once the components are all installed, you may open the sample projects each one after the other and compile them. For each project, do file/open and select the dpr file in the internet directory. Then Project/Build All. Projects are located in SAMPLES\CPP\INTERNET\CB2006\ (or CB2006, CBXE, etc) with a project group in each directory, OverbyteIcsCB2006Sam.bdsgroup, OverbyteIcsCBXe2Sam.groupproj, etc. It is likely that for each project, C++ Builder complains about a missing .res file. This is not a problem, C++ Builder will recreate it as needed. They have not been included to save space in the zip file. Once the components are all installed, you may open the sample projects each one after the other and compile them. For each project, do file/open and select the dpr file in the internet directory. Then Project/Build All. NOTES: - You may have an error message, using Delphi or C++ Builder complaining about Font.Charset, OldCreateOrder and other properties. Those are new properties in newer Delphi or C++ Builder versions, newer than the version you use. You can safely ignore those errors because those properties are not used by the components nor sample programs. You may encounter this error at run time. To avoid it, you must open each form at design time and ignore the error. Then recompile. If you don't ignore the error at design time, you'll have it at runtime ! - If you have Delphi or C++ Builder complaining about a file not found, add .\source directory to your library path. - If you are using C++ Builder you may encounter an error at link time such as "Unable to open file MWBCB30.LIB" (or other libs). This is a bug in C++ Builder. To solve it, you can edit project option file (right click in project manager) and remove any reference to the missing libraries. - Don't forget that the C++Builder components are located in .\delphi\vc32 which is object pascal source code (not a problem for C++Builder, just indicate that the *.pas files are displayed when installing). C++Builder will create the *.hpp files. There are some on-line help files in the VC32 directory. Available VCL Components ------------------------ - The following is a list of the files that should be installed in order to properly add all of the available components in this collection: > OverbyteIcsCharsetComboBox.pas Provides easy MIME charset selection > OverbyteIcsDnsQuery DNS lookup component - useful for getting MX records > OverbyteIcsDprUpdFix.pas IDE plugin for Delphi 2009 and 2010 to update old projects > OverbyteIcsEmulVT.pas ANSI terminal emulation in a control > OverbyteIcsFingCli.pas FINGER client protocol - Find information about user > OverbyteIcsFtpCli.pas FTP client protocol - file transfer > OverbyteIcsFtpSrv.pas FTP server protocol - file transfer > OverbyteIcsFtpSrvT.pas FTP server protocol - helpers > OverbyteIcsHttpAppServer.pas HTTP server protocol - used to build advanced web servers > OverbyteIcsHttpProt.pas HTTP client protocol - used by the web > OverbyteIcsHttpSrv.pas HTTP server protocol - used to build web servers > OverbyteIcsLogger.pas A component to log information > OverbyteIcsMimeDec.pas MIME component - decode file attach, use with POP3 > OverbyteIcsMultiProgressBar.pas A segmented progress bar > OverbyteIcsMultipartFtpDownloader.pas FTP client protocol - download one file using simultaneous connections to speedup download > OverbyteIcsMultipartHttpDownloader.pas HTTP client protocol - download one file using simultaneous connections to speedup download > OverbyteIcsNntpCli.pas NNTP client protocol - send and receive newsgroups messages > OverbyteIcsPing.pas ICMP echo protocol - ping a host > OverbyteIcsPop3Prot.pas POP3 client protocol - get mail from mail server > OverbyteIcsReg.pas Register design components > OverbyteIcsSmtpProt.pas SMTP client protocol - send mail to server > OverbyteIcsSmtpSrv.pas SMTP server protocol - receive mail from client > OverbyteIcsSnmpCli.pas SNMP client protocol - network management > OverbyteIcsSnmpMsgs.pas SNMP client protocol - message helper > OverbyteIcsSysLogClient.pas Syslog Client Protocol - receive syslog messages > OverbyteIcsSysLogDefs.pas Syslog Protocol - helpers > OverbyteIcsSysLogServer.pas Syslog Server Protocol - send syslog messages > OverbyteIcsTnCnx.pas TELNET client protocol - terminal emulation protocol > OverbyteIcsTnEmulVT.pas TELNET and ANSI terminal emulation combined > OverbyteIcsTnOptFrm.pas TELNET Client configuration form > OverbyteIcsTnScript.pas TELNET client protocol - with automation > OverbyteIcsWSocket.pas Winsock component - TCP, UDP, DNS,... > OverbyteIcsWSocketE.pas Register procedure and property editor for TWSocket > OverbyteIcsWSocketS.pas Winsock component for building servers > OverbyteIcsWSocketTS.pas Winsock component for building multithreaded servers - The following list support and utilities units: > OverbyteIcsAsn1Utils.pas ASN1 utilities (for TSnmpClient component) > OverbyteIcsAvlTrees.pas Implements a fast cache-like data storage > OverbyteIcsCharsetUtils.pas MIME-charset functions > OverbyteIcsCookies.pas Client Cookie Handling > OverbyteIcsCRC.pas 32 bit CRC computation > OverbyteIcsCsc.pas character set routines > OverbyteIcsDES.pas Implementation of the Data Encryption Standard (DES) > OverbyteIcsDigestAuth.pas HTTP Digest Access Authentication > OverbyteIcsFormDataDecoder.pas Decode a MIME data block as generated by a HTML form > OverbyteIcsHttpCCodZLib.pas Supports GZIP coding for HttpContCod > OverbyteIcsHttpContCod.pas HTTP Content Coding support, uses extra units > OverbyteIcsIcmp.pas ICMP protocol support, used by the PING component > OverbyteIcsIconv.pas Headers for iconv library (LGPL) > OverbyteIcsLIBEAY.pas Delphi encapsulation for LIBEAY32.DLL (OpenSSL) > OverbyteIcsMD4.pas Implementation of the MD4 Message-Digest Algorithm > OverbyteIcsMD5.pas Implementation of the MD5 Message-Digest Algorithm > OverbyteIcsMimeUtil.pas Support routines for MIME standard > OverbyteIcsMLang.pas A few header translations from MS mlang.h > OverbyteIcsNtlmMsgs.pas Client NTLM authentification messages used within HTTP protocol > OverbyteIcsNtlmSsp.pas Server NTLM authentification of user credentials using Windows SSPI > OverbyteIcsOneTimePw.pas One Time Password support functions, used by FTP > OverbyteIcsSHA1.pas Implementation of US Secure Hash Algorithm 1 (SHA1) > OverbyteIcsSocketUtils.pas Cross platform socket utilities for ICS > OverbyteIcsSSLEAY.pas Delphi encapsulation for SSLEAY32.DLL (OpenSSL) > OverbyteIcsSslSessionCache.pas A very fast external SSL-session-cache component > OverbyteIcsSslThrdLock.pas Implementation of OpenSsl thread locking (Windows);

FireMonkey uses different visual components to VCL, while some non-visual components can be used for both VCL and FMX projects, while other components need special versions, such as ICS. Earlier betas of V8 used the conditional define "FMX" which is *no longer required in project options. Instead in your existing ICS FireMonkey app. add either "Ics.Fmx" to the unit scope names in project options or apply the following changes in the uses clause, rename: OverbyteIcsWndControl -> Ics.Fmx.OverbyteIcsWndControl OverbyteIcsWSocket -> Ics.Fmx.OverbyteIcsWSocket OverbyteIcsFtpCli -> Ics.Fmx.OverbyteIcsFtpCli OverbyteIcsFtpSrv -> Ics.Fmx.OverbyteIcsFtpSrv OverbyteIcsHttpProt -> Ics.Fmx.OverbyteIcsHttpProt OverbyteIcsWSocketS -> Ics.Fmx.OverbyteIcsWSocketS OverbyteIcsSmtpProt -> Ics.Fmx.OverbyteIcsSmtpProt.pas OverbyteIcsPop3Prot -> Ics.Fmx.OverbyteIcsPop3Prot.pas OverbyteIcsNntpCli -> Ics.Fmx.OverbyteIcsNntpCli.pas OverbyteIcsPing -> Ics.Fmx.OverbyteIcsPing.pas OverbyteIcsDnsQuery -> Ics.Fmx.OverbyteIcsDnsQuery.pas OverbyteIcsFingCli -> Ics.Fmx.OverbyteIcsFingCli.pas OverbyteIcsSslSessionCache -> Ics.Fmx.OverbyteIcsSslSessionCache.pas OverbyteIcsSslThrdLock -> Ics.Fmx.OverbyteIcsSslThrdLock.pas OverbyteIcsHttpSrv -> Ics.Fmx.OverbyteIcsHttpSrv.pas OverbyteIcsSocketUtils -> Ics.Fmx.OverbyteIcsSocketUtils.pas OverbyteIcsMultipartFtpDownloader -> Ics.Fmx.OverbyteIcsMultipartFtpDownloader.pas OverbyteIcsMultipartHttpDownloader -> Ics.Fmx.OverbyteIcsMultipartHttpDownloader.pas OverbyteIcsHttpAppServer -> Ics.Fmx.OverbyteIcsHttpAppServer.pas OverbyteIcsThreadTimer -> Ics.Fmx.OverbyteIcsThreadTimer.pas OverbyteIcsCharsetComboBox -> Ics.Fmx.OverbyteIcsCharsetComboBox.pas { Demo units } OverbyteIcsWebAppServerCounter -> Ics.Fmx.OverbyteIcsWebAppServerCounter OverbyteIcsWebAppServerMailer -> Ics.Fmx.OverbyteIcsWebAppServerMailer The list above is also the list of units that now have different names in the FireMonkey framework however most of them share the same source file. Dropping a ICS component on the form will add the correct unit name for each framework automatically (don't forget to disable the package cache as described above). Unit OverbyteIcsLibrary.pas has been *deprecated* and ICS IPv8 doesn't use it anymore. If you used it in your own code read the comment in OverbyteIcsLibrary.pas, search for "deprecated". Sample applications: -------------------- With V8, the sample applications are now grouped into directories according to general functionality, to make it easier to compare related samples. Many samples are similar. When searching for something, always look at the date the demos where created. The most recent is always the best code! In the lists below, ACTIVE!! indicates applications that are actively maintained to test and support new functionality in the ICS components.

Two samples are not in the project group since they need extra components installed > OverbyteIcsRestDemo.drp Demo program showing how to use REST API from Google and Yahoo > OverbyteIcsRestJsonDemo.drp Demo program showing how to use REST API from Google Search and JSON Sample Notes ------------ Note 1: Not all samples have been rewritten in C++ for C++ Builder. And those rewritten are frequently much simpler. So C++ Builder user: have a look at the Delphi sample too ! Note 2: Follow "UserMade" link on ICS web site to find more sample programs written by ICS users. As explained in the component installation, you may encounter an error loading a sample application or running it. This may be because the last time I loaded the form, I was using another Delphi or C++ Builder version which has new properties. You can safely ignore messages related to those new properties. They are not used in the samples. (The properties are CharSet, OldCreateOrder and others). You can also encounter error about duplicate resources. You can ignore them safely. If you have those errors, open each form in the IDE, ignore the error then recompile. If you don't open the form in the IDE, you'll get the errors at runtime and your program will abort. When installing a new version, always delete old dcu, obj, dcpil and always recompile everything ! Close everything before recompiling the library or packages. When installing a new version, be sure to unzip it in the same directory tree as the old one or you'll mess both versions. About SSL: ---------- TSslWSocket and TSslWSocketServer component are derived from the standard TWSocket and TWSocketServer component. The SSL code is compiled into the component only if you define USE_SSL symbol to your packages and projects. Just add USE_SSL to the defines in the project or package options and recompile everything. The components make use of LIBEAY32.DLL and SSLEAY32.DLL to handle SSL protocol stuff. The DLLs are dynamically loaded at runtime. It means that the DLLs will only be required at runtime when you first make use of a SSL function. Your applications will run on systems without OpenSSL DLLs as long as you don't call any SSL function. The files may be downloaded from: http://wiki.overbyte.be/wiki/index.php/ICS_Download Most ICS components have their SSL enabled counter part. They work exactly the same way as the regular component except when SSL specific stuff is needed, for example certificates. To support SSL stuff, the SSL-enabled version use some new properties, events and methods. Many sample programs have their SSL-enabled counter part in a separate sources located in SslInternet folder. SSL certificates: To make use of SSL, you frequently need certificates. I provide some demo certificates I built using command line OpenSSL tool. PEM certificates can be opened by a text editor, LF as well as CRLF are allowed as line breaks. CACERT.PEM : A demo certificate for "Example CA" 01CERT.PEM : A demo certificate which is signed by CACERT.PEM 01KEY.PEM : A demo private key for 01CERT.PEM Passphrase is "password". CLIENT.PEM : A demo certificate and private key. Passphrase is "password". SERVER.PEM : A demo certificate and private key. Passphrase is "password". ROOT.PEM : A demo CA certificate. Passphrase is "password". TRUSTEDCABUNDLE.PEM : A demo CA file in PEM format containing multiple well known root CA certificates to be specified in property CA Path of the demo applications. Read the comments included in this file. 6F6359FC.0 : Located in sub directory SslInternet\TrustedCaStore, it's the file CACERT.PEM stored with a hashed file name. Directory TrustedCaStore can be specified in property CA Path of the demo applications. For details about certificate, see the excellent book: "Network security with OpenSSL", O'Reilly, ISBN 10: 0-596-00270-X The SSL demo project OverbyteIcsPemTool may be used to create self signed PEM certificates, certificate requests for commercial use, to convert existing certificates in the Windows Certificate Store to PEM format understood by OpenSSL and to examine PEM certificates. You will find more information in IcsSslHowTo.txt file. Commercial SSL certificates: To avoid browsers giving certificate warning messages, you need to purchase a SSL certificate from one of numerous companies, such as Verisign, Thawte GeoTrust or RapidSSL. Prices vary dramatically and are often cheaper from resellers such as Servertastic than from the main issuing companies. The main purpose of an SSL certificate is to prove the identity of the owner of a web site, ideally the company behind the web site. That usually requires paper work identifying the company is submitted and also proof the domain being protected is owned by that company, it usually also involves telephone calls. Such certificates are usually called fully validated and cost $120 or more each year for a single domain, ie secure.website.com. Wild card certificates cost $350 or more, but protect multiple sub-domains, ie web.website.com as well. Extended Validation certificates cost from $450 a year, and show the company name in green in the address bar. For testing and simple use, instant issued SSL certificates cost from $15 per year and protect a single domain only with automated checking reducing the cost (an email to admin@website.com to prove you receive email for the domain, perhaps a telephone call as well). Note these instant certificates do not include a company name. To buy and install an SSL certificate for use with ICS and OpenSSL follow these steps: 1 - Build the SSL demo project OverbyteIcsPemTool. Take Extras, Create Certificate Requests, fill in the various fields (check other certificates if uncertain, the Common Name is the domain to protect, ie secure.website.com and E-Mail should be an email address at the than domain, ideally admin or administrator, 2048 bits. Click Create, and specify two file names, first for the private key (mykey.pem) then the certificate request file (myreq.pem). The request can also be done using OpenSSL command line arguments, or you can build it into your own application. 2 - Choose you SSL supplier and certificate type, at some point during the ordering process you will be asked for the certificate request, so open the PEM file you saved with a text editor and copy the base64 encoded block starting -BEGIN CERTIFICATE REQUEST- into the web form. It should be decoded and displayed so you check it's correct. The private key is not needed for the certificate to be issued. At this point the validation process starts as mentioned above, which might take hours or weeks to complete. 3 - Eventually the SSL certificate should be issued, either by email or made available to download from the supplier's web site. It should be in X.509 format in a base64 encoded block starting -BEGIN CERTIFICATE- which should be saved as a PEM file (mycert.pem). There should also be an Intermediate CA certificate, with which your new certificate was signed, which should also be saved as a file (mycacert.pem). This may also be downloadable from the supplier as a bundle file and should be common to any certificates they issue, ie RapidSSL_CA_bundle.pem. 4 - The OverbyteIcsPemTool tool has a View PEM button that allows examination of your new PEM files. 5 - The three PEM files now need to be attached to the SslContext component in your application, with properties SslCertFile, SslPrivKeyFile and SslCAFile. The request certificate file has no further use. Support: -------- There is a mailing list to discuss F. Piette's components and applications. To subscribe surf to http://lists.elists.org/mailman/listinfo/twsocket. Do not use an aliased EMail address, use your real EMail address, the one you'll use to post messages. After asking for subscription, you'll receive a confirmation email you must reply to it or you will _not_ be added to the subscriber's list (this is to check for email path and also make sure someone doesn't subscribe you without your consent). Once you have been registered with the mailing list processor, you can send messages to twsocket@elists.org. Every subscriber will receive a copy of your message. I will respond, but anybody is welcome to respond to each other's messages. So every body can share his expertise. There are many other useful mailing lists at http://www.elists.org ! Before asking a question, browse the message archive you can download from the support page on the web site (click the "support" button from main page) and from the mailing list web site http://lists.elists.org/mailman/listinfo/twsocket. Google is also archiving the list with some delay. If you found a bug, please make a short program that reproduces the problem attach it to a message addressed to me. If I can reproduce the problem, I can find a fix ! Do not send exe file but just source code and instructions. Always use the latest version (beta if any) before reporting any bug. You are also encouraged to use the support mailing list to ask for enhancements. You are welcome to post your own code. The support mailing list has sometimes a heavy traffic. If it is too much for you, you can select "digest" mode in which mailing list processor will mail you only one big message per day. To select digest mode goto http://lists.elists.org/mailman/listinfo/twsocket. You can also subscribe to another mailing list called twsocket-announce which will receive only very few messages when major bug fixes or updates are done. The subscription process is the same as for the other mailing list. See above procedure. Release notes ------------- There is no global release notes. Each component and sample has his own history. You can find those histories in the comment in the beginning of each source file. There are also a bunch of useful comments in the source code. You should at least browse the source for the components you are interested in. MidWare ------- If you wants to build client/server applications using TCP/IP protocol, you can do it easily with ICS. But you can do it much more easily using another freeware product from Fran鏾is Piette: MidWare. Available from the same web site http://www.overbyte.be. francois.piette@overbyte.be francois.piette@swing.be http://www.overbyte.be/ http://wiki.overbyte.be/
