struts 2.0（web工程Struts2_HelloWorld）初探报错

[fengxiarong707]

报错：
HTTP Status 404 - /Struts2_HelloWorld/HelloWorld

--------------------------------------------------------------

type Status report

message /Struts2_HelloWorld/HelloWorld

description The requested resource (/Struts2_HelloWorld/HelloWorld) is not available.


---------------------------------------------------

环境：
jakarta-tomcat-5.5.7
jdk 1.5
struts-2.0.9
eclipse 3.2

web工程Struts2_HelloWorld描述：
stuts.xml配置:
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<include file="struts-default.xml"/>
<package name="tutorial" extends="struts-default">
<action name="HelloWorld" class="tutorial.HelloWorld">
<result>HelloWorld.jsp</result>
</action>
</package>
</struts>
自建有HelloWorld.java、SayHello.jsp、Helloworld.jsp三个文件。


启动tomcat时，有个警告：
信息: Parsing configuration file [struts.xml]
2007-7-29 16:29:43 org.apache.struts2.config.Settings getLocale
警告: Settings: Could not parse struts.locale setting, substituting default VM locale
2007-7-29 16:29:45 com.opensymphony.xwork2.util.ObjectTypeDeterminerFactory <clinit>


请问各位大侠，该如何解决？在此感谢！

try try:
creating a /WEB-INF/classes/struts.properties file with struts.locale=en_GB

[fengxiarong707]

直接在地址栏位中输入：http://localhost:8080/Struts2_HelloWorld/HelloWorld.action

报错：
There is no Action mapped for namespace / and action name HelloWorld. - [unknown location]
com.opensymphony.xwork2.DefaultActionProxy.prepare(DefaultActionProxy.java:186)
org.apache.struts2.impl.StrutsActionProxyFactory.createActionProxy(StrutsActionProxyFactory.java:41)
org.apache.struts2.dispatcher.Dispatcher.serviceAction(Dispatcher.java:494)
org.apache.struts2.dispatcher.FilterDispatcher.doFilter(FilterDispatcher.java:419)

1.create struts.properties 也没用；
2.在struts.xml中加入：<constant name="struts.locale" value="en_US" />也没有用。

启动时有两次警告：
Settings: Could not parse struts.locale setting, substituting default VM locale

[wangzhouyu]

Struts2_HelloWorld/HelloWorld，HelloWorld是什么，是一个action么？看看你的web.xml配置的filter是对那些名进行过滤。

[Cappuccino_mhc]

我也在求2.0

[fengxiarong707]

我就照搬网络上一篇struts 2.0的初探，咋就不通过。
web.xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<display-name>Struts 2.0 Hello World</display-name>
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
</web-app>

HelloWorld.java:

package tutorial;
import com.opensymphony.xwork2.ActionSupport;
public class HelloWorld extends ActionSupport {
private String name;

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String execute() {
name = "Hello, " + name + "!";
return SUCCESS;
}

}

[fengxiarong707]

工程是在eclipse下用web --> dynamic web project 建立的，导入相应的包，这样子运行后就报404的错；
现在我用 java -->Tomcat project 创建工程，就没有问题了，启动时虽也有警告。

仍希望有大侠能给出why。

[huangtut]

我也是报错，我用的是eclipse3.2.1，引入了struts2.0.9 lib 下的包，刚建了index.html，可惜启动的时候报错

楼上兄弟不要导入-plungin的包，这个应该就ok了。
明晚结贴。

[pengxuan]

我也遇到这种问题,是由于struts.xml发布位置引起的

在myeclipse开发环境中,struts.xml的位置应该在src目录下,不应该在WEB-INF目录下!

[masterlife21]

问题你怎么解决的，我遇到同样的问题,警告是没有了。
但是找不到map....

[fengxiarong707]

开始工程是在eclipse下用web --> dynamic web project 建立的，导入相应的包，这样子运行后就报404的错；
现在我用 java -->Tomcat project 创建工程，就没有问题了，启动时虽也有警告。

楼上兄弟如果还有问题，把错误信息贴出来看看。

[龙翔飞雪]

我也碰到这个问题, 找了很多帖子, 大多回答差不多...
关键错误是:
Unable to load bean: type:com.opensymphony.xwork2.ObjectFactory class:org.apache.struts2.spring.StrutsSpringObjectFactory

后来我发现:
1. 首先不要有多余的jar, commons-logging-1.1.jar freemarker-2.3.8.jar ognl-2.6.11.jar struts2-core-2.0.6.jar xwork-2.0.1.jar是struts2必须的 (小版本号不同无所谓)
2. 直接在MyEclipse里运行tomcat, 好像每次必定碰到这个错误 (这个错误是由于struts-plugin.xml引起的), export成.war, 放到tomcat里, 就成功了.
(难道MyEclipse里面做了什么多余的东东?? 不明, 我用的是MyEclipse6, 被这个问题困惑了很久)

怎么没有人理我啊？？？？
