Re: Stuts forwarding does not work

Thu, 13 Jan 2005 06:51:31 -0800

Actually now it works. I moved everything to another application name and it started working. But, another problem. When I submit my page I get a blank page. Action class does not do anything, just forwards to success page. Here is the action mapping in struts-config.xml:

<!-- =================================== Global Forward Definitions -->

   <global-forwards>
       <forward
           name="test"
           path="/Test.do"/>
   </global-forwards>


<!-- =================================== Action Mapping Definitions -->

   <action-mappings>

       <action
           path="/Test"
           type="org.apache.struts.actions.ForwardAction"
           parameter="/pages/Test.jsp"/>

       <action
           path="/QuerySubmit"
           type="app.ExecuteQueryAction"
           name="ExecuteQueryForm"
           scope="request"
           validate="true"
           input="/pages/Test.jsp">
           <forward
               name="success"
               path="/pages/QueryResults.jsp"/>
       </action>
   </action-mappings>

And ActionClass:

package app;

import java.io.IOException;
import java.util.Vector;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionServlet;
//import com.kwi.DBDriver;


public final class ExecuteQueryAction extends Action {

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

       // Obtain username and password from web tier
       String sqlQuery = ((ExecuteQueryForm) form).getSQLQuery();

       // Return success
       return mapping.findForward("success");

   }

} // End LogonAction

The same blank screen after submit happens when I deploy and run application logon.war from Husted's Struts In Action source code. So may be my struts installation is wrong?

thanks a lot,
Alex

I am trying to redirect from index.jsp to another page but no luck. I get this error:

   ------------------------------------------------------------------------

my struts-config.xml looks like this:

<!-- =================================== Global Forward Definitions -->

   <global-forwards>
       <forward
           name="queryInput"
           path="/queryInput.do"/>
   </global-forwards>


<!-- =================================== Action Mapping Definitions -->

   <action-mappings>

<action
path="/queryInput"
type="org.apache.struts.actions.ForwardAction"
parameter="/pages/QueryInput.jsp"/>
</action-mappings>



thanks,
Alex
