Including Actions via jsp:include
hi Guys, I bet this has come up before... I need to include the output of an action in a jsp, using the jsp:include tag lie this: jsp:include page=/myAction.do flush=true jsp:param name=USERID value=CARLOSUS / /jsp:include but I get an illegalstate exception, as the ActionServlet forwards instead of includes... is there anyway to do this??? thanks :: Mikkel Bruun Senior IT Developer [EMAIL PROTECTED] Direct: +45 32 88 22 73 Valtech A/S Kanonbaadsvej 10 DK-1437 Copenhagen Tel +45 32 88 20 00 Fax +45 32 88 20 20 -Oprindelig meddelelse- Fra: Debasish Ghosh [mailto:[EMAIL PROTECTED]] Sendt: 03 September 2001 11:35 Til: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Emne: Re: Dynamic Forwarding ... Thanks, Ted, for the reply. Actually, I am not forwarding from Action to Action. The mapping of the forward dummy resolves to a JSP named dummy.jsp and not an action (*.do). From an action, on submit, I would like to tansfer control to a JSP to accept more inputs. Along with this control transfer, I would like to pass a parameter to indicate some logic. I finally did this using a request.getParameter( formName ) in the JSP as a scriplet, and declaring a hidden property in the JSP : html:hidden property=formName value=%= formName % / Now I can access this property from the action class of the form dummyForm. Please suggest, if there is a better method of doing this (without the scriplet). Regarding the link that u have mentioned, I had already gone thru it. I do not understand one point. If I have a form formA, having a property formName, then when I forward to another form, formB, how will the property be retained as part of formB ?

If formName is a property in the ActionForm, then it shuld be populated. I would try using request.getParameter(formName) and see if that's null too. I'd also try hardcoding the value for action to be sure that is not null.

In the Action class where I am preparing the forward URL, I am doing the following : ActionForward fwd = mapping.findForward(dummy); StringBuffer path = new StringBuffer( fwd.getPath() ); path.append( ?formName= ).append( action ); return new ActionForward( path.toString(), fwd.getRedirect() ); With this, I am getting the correct parameter to ActionForward, and the control is also forwarded to the appropriate JSP. But I am not able to access the passed-in parameter. I have a property named formName in the called form. But from the action of the called form, when I access the property getFormName(), I get NULL. In order to achieve this, do I have to declare anything in the JSP ? Please help !! Regards. - Debasish __ Do You Yahoo!? Get email alerts NEW webcam video instant messaging with Yahoo!

Re: Including Actions via jsp:include
hi Guys, I bet this has come up before... I need to include the output of an action in a jsp, using the jsp:include tag lie this: jsp:include page=/myAction.do flush=true jsp:param name=USERID value=CARLOSUS / /jsp:include but I get an illegalstate exception, as the ActionServlet forwards instead of includes... is there anyway to do this??? thanks I've found one workaround which can help in some situations: make the Action.perform return null. include the view (JSP) then. So it could look like this: jsp:include page=/myAction.do flush=true jsp:param name=USERID value=CARLOSUS / /jsp:include jsp:include page=/myAction.jsp flush=true / But it is ugly indeed. -- gR

whoa! thanks alot... does this hack work on all servers???

Re: Including Actions via jsp:include
:-) The question is not, whether it works on different servers, the question is, whether the original including of forwarding Action works on some servers. If the Action.perform returns null, then there is no forward and no reason for such an exception. The real problem with this solution is that it breaks the MVC pattern. In order to make it work, your VIEW (your JSP) which includes the action, decides how to display the action's results. It does so by incluing the second *.jsp. But this decision should be made by the action itself in cooperation with the ActionServlet. (The action decides what is the logical result e.g. success and the action servlet maps it to the physical *.jsp or whatever is defined in struts-config.xml) -- gR - Original Message - From: Mikkel Bruun [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, September 03, 2001 12:19 PM Subject: SV: Including Actions via jsp:include whoa! thanks alot... does this hack work on all servers???
