Alex,
Check the Javadocs because the perform() method is GONE in Struts v1.2.4,
deprecated in v1.1, and normal for the old v1.0. So, what version are you
using? Probably v1.2.4 since defining perform() like that will never be
called resulting in a standard dummy execute() method being invoked which,
TADA, returns a blank page by default!
Regards,
David
P.S. Check your computer's time. It looks like you sent your messages over
a day ahead of us. Considering daylight savings time only allows for a 24
hour window, I'm guessing your computer's (whichever one you send email
from) time might be off just a little, a tad, a pinch, a smidgeon, etc.

Subject: Re: Stuts forwarding does not work
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

<action-mappings>

parameter="/pages/QueryInput.jsp"/>
</action-mappings>
thanks,
