Thanks for the quick reply
You could find the entire StackTrace at the end of this mail.
What I understand is :
- the MyFacesGenericPortlet subclasses the javax.portlet.GenericPortlet
class
- Websphere uses Jetspeed 1. Jetspeed portlet subclasses the
org.apache.jetspeed.portlet.Portlet class.
- Websphere may try to cast the MyFacesPortlet in PortletAdapter class,
and fails.
I tried to use the Websphere class
(com.ibm.faces.webapp.WPFacesGenericPortlet), but without success.

Sean Schofield a �crit :
Tree2 should work in any J2EE cotainer with any JSF implementation. I
haven't used it with portlets but you seem to be describing a portlet
problem ... Why don't you give us more information (stack trace)
about the ClassCastException?

I used successfully the tree2 component with Jetspeed 2, using the
org.apache.myfaces.portlet.MyFacesGenericPortlet portlet-class.
I recently switched to Websphere Portal Server 5, but the container
throws a ClassCastException...
I think the problem is that Websphere portlets must subclass the
PortletAdapter class.
Is there any chance to use the tree2 component in WebSphere ?
Thanks.
