Thanks inadvance,

Hi All,

I am new to JSF jsr168 portlet development, I have created 2 portlets and 2 face managed beans using option (Face Managed Bean in PAGE DATA view in RAD) and made them application scope.

I want to use some methods and variables defined in first bean in 2nd bean ( order of flow of those pages is 1 and then 2 JSF ). I thought to extend first Face managed bean but my 2nd face managed bean is already existing a class,


my doubts :


1) can i use already existing face managed bean in another managed bean, if so how. do i need to create a new instance of first managed bean using new operator (which i feel violates JSF framework).


its very urgent and any help is appreaciable.

Hi Cameron,

your tutorial regarding JSF portlet at your site is really good and helpful.

It would be good if give one more example of JSF portlet using RAD by creating portlet project.

Currently I am facing problems with wiring and couldnt understand concept behind it( how to pass more than one parameter using wiring). It would be good if you add example regarding wiring too.

If possible please suggest good book on JSF jsr168 portlet for better understanding.

hoping for your reply,


Thanks,
