急问:用JBuilder2005遇到的问题

05-04-05 kevinfield

最近刚刚用JBuilder2005遇到的奇怪问题(而且是JBuilder2005更新过之后的........郁闷)
无意中发现JBuilder2005 有奇怪问题
1.我按照JBuilder2005上面的说明,打开了Struts1.1的示例程序,但是老提示说有一些jsp文件无法编译(我是按照JBuilder help上面一步一步下来的,但是还是有错)
2.我按照JBuilder2005的help中的"Tutorial: Creating a Struts web application"按部就班的建立了一个hello示例程序
具体文件如下:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

<struts-config>
<form-beans>
<form-bean name="userActionForm" type="strutsexample.UserActionForm" />
</form-beans>
<action-mappings>
<action input="/hello.jsp" name="userActionForm" path="/userAction" scope="session" type="strutsexample.UserAction">
<forward name="goodbye" path="/goodbye.jsp" />
</action>
</action-mappings>
</struts-config>

配置文件定义完全正确,但是在运行的时候发生如下错误:
HTTP Status 500 -

请比较熟悉的JBuilder2005的高手们指点
不胜感激!!!!!!

struts-config.xml配置文件如下:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

<struts-config>
<form-beans>
<form-bean name="userActionForm" type="strutsexample.UserActionForm" />
</form-beans>
<action-mappings>
<action input="/hello.jsp" name="userActionForm" path="/userAction" scope="session" type="strutsexample.UserAction">
<forward name="goodbye" path="/goodbye.jsp" />
</action>
</action-mappings>
</struts-config>

不是你提交表单页面里action属性写错了,就是这个xml配置文件里的这一段有问题，看看你的ａｃｔｉｏｎ和这里的path是否匹配
<action input="/hello.jsp" name="userActionForm" path="/userAction" scope="session" type="strutsexample.UserAction">

hello.jsp文件如下:

<jsp:setProperty name="bean0" property="*" />
<body bgcolor="ffff00">

<html:form action="/userAction.do" method="post">

goodbye.jsp如下:

麻烦那位高手帮看一下,到底是我的文件有问题,还是JBuilder2005有问题
不过我爸war文件放到Tomcat下面单独测试,还是出现同样的问题

在你的action类里，最后转发页面的时候,应该是这行代码

// ActionMapping.findForward("goodbye");
<p class="indent">

在goodbye之前没有那一个斜杠
