[jboss-user] [JBoss Seam] - Re: Seam2 as portlet

[jarkko@jab.fi]

Ok,
 After getting the sources for jsf-portet.jar (com.sun.faces.portlet)  I managed to make same progress. I've get output from XHTML!

There's couple issues with com.sun.faces.portlet.FacesPortlet. First the method getFacesContextFactory() always uses com.sun.faces.context.FacesContextFactoryImpl instead of com.sun.faces.portlet.FacesContextFactory. This causes issues and has to be fixed. 

Broken getFacesContextFactory() from com.sun.faces.portlet.FacesPortlet. I just don't know to to wire FactoryFinder to use com.sun.faces.portlet.FacesContextFactory.

  |    public FacesContextFactory getFacesContextFactory() throws PortletException{
  |         if (facesContextFactory != null) {
  |             return facesContextFactory;
  |         }
  |         // Acquire our FacesContextFactory instance
  |         try {
  |             facesContextFactory = (FacesContextFactory)
  |             FactoryFinder.getFactory
  |                     (FactoryFinder.FACES_CONTEXT_FACTORY);
  |             logger.log(Level.FINEST, "PS_CSFP0010", facesContextFactory);
  |         } catch (FacesException e) {
  |             Throwable rootCause = e.getCause();
  |             if (rootCause == null) {
  |                 throw e;
  |             } else {
  |                 throw new PortletException(e.getMessage(), rootCause);
  |             }
  |         }
  |         return facesContextFactory;
  |     }
  | 

So I overrided the methodin custom portlet class:

  | 	@Override
  | 	public FacesContextFactory getFacesContextFactory() throws PortletException {
  | 
  | 		if (facesContextFactory != null) {
  | 			return facesContextFactory;
  | 		}
  | 
  | 		facesContextFactory = new com.sun.faces.portlet.FacesContextFactoryImpl();
  | 
  | 		return facesContextFactory;
  | 	}
  | 



Also FacesPortlet.getLifecycle() uses the same javax.faces.FactoryFinder which has hardcoded/or just I known know how names for factories.

I also override getLifecycleFactory() and getLifecycle() to return classes from com.sun.faces.portlet.

In  getLifecycle() copy the phaselisteners  from super.getLifecycle() to here. super.lifecycle has all the phaselisteners EL,Seam, and our custom phaselister from faces-config.


  | Lifecycle superLifecycle = super.getLifecycle();
  | 			PhaseListener phs[] = superLifecycle.getPhaseListeners();
  | 			for (PhaseListener phaseListener : phs) {
  | 				lifecycle.addPhaseListener(phaseListener);
  | 			}
  | 

Then I simply make kick Seam with this new portlet lifecycle stuff in my portlet class:

  | 	@Override
  | 	protected void doDispatch(RenderRequest request, RenderResponse response)
  | 			throws PortletException, PortletSecurityException, IOException {
  | 
  | 		FacesContext context = getFacesContextFactory().getFacesContext(
  | 				getPortletConfig().getPortletContext(), request, response,
  | 				getLifecycle());
  | 
  | 		ExternalContext externalContext = context.getExternalContext();
  | 
  | 		// Kick start Seam Contextes
  | 		FacesLifecycle.beginRequest(externalContext);
  | 
  | 		super.doDispatch(request, response);
  | 		
  | 		// Tell Seam Lifecycle manager that're about to end request
  | 		FacesLifecycle.endRequest(externalContext);
  | 		
  | 	}
  | 


I also've custom FaceletViewHandler with modified createResponseWriter, which is related to facelets and available from Facelets site.

So, basic stuff seems to work now. Let's see how conversations and others work.
