我知道并收到此错误:对于此代码:

struts-config.xml

Hi I''m amit and getting this error: for this code:

<action-mappings>
        <action input="/jsp/index.jsp" name="TestForm" parameter="test" path="/test" scope="request" type="TestDispatchAction"/>
        <forward name="pass" path="/jsp/Next.jsp"/>
        <forward name="fail" path="/jsp/index.jsp"/>

 <html:submit property="loginButton" value="Login Here"/>
 <html:submit property="testButton" value="Test Only"/>
 </html:form>

TestDispatchAction

TestDispatchAction

public class TestDispatchAction extends DispatchActio
 {  private final static String SUCCESS = "success";
    public ActionForward loginAction(ActionMapping mapping, ActionForm  form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        TestForm f=(TestForm)form;
        String name=f.getTextName();
        String pass=f.getTextPass();
        String logic="fail";
        if(name.equals(pass))
        {
            logic="pass";
        }
        else
        {
            logic="fail";
        }
        return mapping.findForward(logic);
    }

    public ActionForward testAction(ActionMapping mapping, ActionForm  form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {
        TestForm f=(TestForm)form;

        return mapping.findForward(SUCCESS);
    }
}

推荐答案

第一件事是该类看上去很奇怪:

First thing is the class looks odd:

public class TestDispatchAction extends DispatchActio {
  [...]
}

超类应为DispatchAction.

The super class should be DispatchAction.
