  请各位高手能够指点下org.apache.struts.actions.dispatchAction的用法，或者哪里有org.apache.struts.actions.dispatchAction的相关质料，谢谢！！！

------解决方案--------------------
在struts-config中，配置parameter参数
比如

XML code

<action path="/xxx"
        name="myForm"
        type="xxx.XxxAction"
        ...
        parameter="flag">

------解决方案--------------------
请求的路径上缺少参数：method=方法，

------解决方案--------------------
 <form action="loginAction.do?method=login" method="post">
   	UserName:<input type="text" name="username"/><br>
