I have a JSR168 portlet in WebSphere portal 5.1 .
I have saved data in application-scope of the portlet session.
How can I retrieve that data at the servlet end.
My servlet gets invoked from a JSP on the portlet.

If you are dispatching the rendering to the Servlet/JSP and you include the data into the Application scope, then you will have access to it. Remeber according to the spec, the Portlet Session object is a wrapper around the HTTPSession object.

Attributes stored in PortletSession are accessable from the ServetSession and vice versa. So just set an attribute in the portlet session and access it from the servlet or jsp as usual.

It is sorta covered in the JavaRanch Style Guide.
