RE: Mapping issue

This is my application error log,

DEBUG - Path Based Include
DEBUG - insert page='/portal/forms.jsp'.
DEBUG - servletPath=/portal/forms.jsp, pathInfo=null, queryString=null, name=null
DEBUG - Path Based Include
ERROR - Servlet.service() for servlet jsp threw exception

This is the forms.jsp,

<%@ page import="java.util.*" %>

<html>
<body>
<h1 align="center">Forms Listing</h1>
<p>

<%
 ArrayList forms = (ArrayList)request.getAttribute("forms");
 Iterator it = forms.iterator();

 while(it.hasNext()) {
   out.print("<br>try " + it.next());
 }

%>

</body>
</html>

...and this is the code that sets the attribute forms.jsp is tryimng to access,

public final class RetrieveFormAction extends Action {

private final static Logger log = Logger.getLogger(RetrieveFormAction.class);

public ActionForward execute(ActionMapping mapping,
ActionForm form, HttpServletRequest request,
HttpServletResponse response)
//throws IOException, ServletException {
throws Exception {

        ArrayList forms = new ArrayList();
       String userName = ((LogonForm) form).getUsername();

        DataSource dataSource = getDataSource(request, "userDB");
        Connection conn = dataSource.getConnection();
        Statement stmt = conn.createStatement();

        ArrayList result = forms;
        request.setAttribute("forms", result);
        return mapping.findForward("show_forms");

 }
}

What is it?

Have you checked your application server's log files to see if there were
any Struts startup errors?  Where are you putting the "struts-conf" file?
Are you putting it in the file "/WEB-INF/struts-config.xml"?

Regards,
David

To all,

This is my error message in the browser,

javax.servlet.ServletException: Cannot retrieve mapping for action
/SelectUser

The class files are in the right place.  This is struts-conf,

<form-beans>
    <form-bean name="ReturnStudentForms"
               type="app.model.FormsSelect" />
  </form-beans>

<action-mappings>

  <action-mappings>
    <action path="/SelectUser"
            type="app.web.RetrieveFormAction"
            name="ReturnStudentForms" scope="request"
            validate="true" input="/portal/user.jsp">
        <forward name="show_forms"
                 path="/portal/forms.jsp" />
    </action>
  </action-mappings>


Thanks,
Jim
