process action JSF Portlet

Hello,
I'm developing the jsf portlet for IBM Webspera, and for several day I can't solve the problem with portlet communication.
The first portlet wich is developed by the project partners sends the action with parameter. If a receive that event according parameter passed I should fill it with information from database.
Maybe you could give me any suggestions?

I should recieve
portlet ACTION request with parameters
action="DISPLAY_ITEM"
documentId=<item ID>
keywords=<search keywords>

Thank you in advance,
Ina

No one knows the answer???

Hi Ina,

It is very simple to have JSF portlet in Liferay.

Here are examples (a lot of real examples):

SUN JSP,

SUN Facelets,

ICEFace,

etc.

Thanks for reply Jonas, but I'm already using ibm portlet bridge and I only need to add the mentioned functionality to my portlet. I'm developing with IBM Rational application developer 7 for IBM Websphera 6.

After hours of searching I achived that my portlet is catching the event, but the ridirect is not working correctly. I use request.getPortletSession().setAttribute("com.ibm.faces.portlet.page.view", "/FGITB/FGITBSavDetailView.jsp"); as sugested in IBM page, but no redirect. I also tried the PortletRequestDispatcher, but the my page is jsf, and I get lots of errors, like nullpointer exeption.
Any suggestions?
