Eclipse整合Tomcat做第一个Struts遇到的问题

[jzpone]

程序很简单，就是提交一个名为input的form，输入http://localhost:8080/hello/form/input.jsp,错误如下：
/////////////////////////////////////////////////
type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

第一次写Struts,期望很大，希望高手指点！

顶一下

[anin2000]

可能是struts_config.xml加载的问题，在Eclipse中启动tomcat也没有错吗？如果没有错，那就核对路径和大小写，如果有就注意.xml的保存方式。

[jzpone]

顶一顶，要不然沉了

[ginflzz]

没有过structs
你找找ActionMappings or ActionFormBeans 在哪
上面说，ActionMappings or ActionFormBeans 这变量名没有找到
再看看这段代码
<action-mappings>
<action
attribute="inputForm"
input="/form/input.jsp"
name="inputForm"
path="/input"
type="com.jzp.struts.action.InputAction" />
</action-mappings>

[myxd]

把你jps代码也贴出来

[jzpone]

以下是input.jsp代码：
/////////////////////////////////////////
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<html>
<head>
<meta name = "Generator" content = "Easy Struts Xslt generator for Eclipse (http://easystruts.sf.net).">

<title>Struts Form for inputForm</title>
</head>
<body>
<html:form action="/input">
name : <html:text property="name"/><html:errors property="name"/></br>
<html:submit/><html:cancel/>
</html:form>
<body>
</html>

[jzpone]

没人知道吗？
又要沉了，up!

[anin2000]

web.xml有没有配置正确？com.jzp.struts.form.InputForm有没有？

[jzpone]

com.jzp.struts.form.InputForm存在

web.xml如下：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts-config (View Source for full doctype...)>
- <web-app>
- <servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
- <init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
- <init-param>
<param-name>debug</param-name>
<param-value>3</param-value>
</init-param>
- <init-param>
<param-name>detail</param-name>
<param-value>3</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
- <servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>

[bibiye]

应该是路径出错

[telent]

我和你有同样的问题，希望快点解决。

[hxdhjsoo]

给出你的配置文件
肯定是配置文件错了

[fantasyCoder]

程序和配置文件没社么错误！
可能是加载时的错误！
楼主应该用的时easystruts吧！
大多数会帮你自动配置！
