Subject Problems with JSR-168 portlets over Portal Engine.
Date Tue, 09 Nov 2004 12:32:04 GMT

Hi, I need help with Portal Engine. I have two problems with JSR-168
portlets.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. I'm trying to use the RequestDispatcher  from JSR-168 portlets using the
code below:

   PortletRequestDispatcher rd =
getPortletContext().getRequestDispatcher("/WEB-INF/page.htm");
   try {
            rd.include(request, response);
   } catch (PortletException pe) {}

But I always get the following error message:

   ERROR   (2004-11-09) 12:58.07:864   [portal]
(/webapp/samples/blocks/portal/portal) http-8080-Processor24/LoggerImpl:
PortletInvokerImpl.action() - Unable to find RequestDispatcher.

Anybody knows why it doesn't work? Thanks in advance.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
2. I canĀ“t update programmatically a JSR-168 portlet preference using code
like this:

   PortletPreferences PP = request.getPreferences();
   try {
            PP.setValue("preference","value");
            PP.store();
   } catch(ReadOnlyException roe) {} catch(ValidatorException ve) {}

It seems to be a problem with the preferences validator, because I always
get this message:

ERROR   (2004-11-09) 13:17.47:030   [portal]
(/webapp/samples/blocks/portal/portal)
http-8080-Processor23/PortletPortalManager: Error during processing of
portlet action.
java.lang.IllegalStateException: Portlet class loader not yet available to
load preferences validator.
