Class PortletHttpSessionWrapper

java.lang.Object
  org.apache.wicket.portlet.PortletHttpSessionWrapper

All Implemented Interfaces:

InvocationHandler

public class PortletHttpSessionWrapper
extends Object
implements InvocationHandler

Proxy for a Servlet HttpSession to attach to a PortletSession, providing only access to PORTLET_SCOPE session attributes and hiding the APPLICATION_SCOPE attributes from the Servlet.
This Proxy can be used to isolate two instances of the same Portlet dispatching to Servlets so they don't overwrite or read each others session attributes.
Caveat: APPLICATION_SCOPE sessions attributes cannot be used anymore (directly) for inter-portlet communication, or when using Servlets directly which also need to "attach" to the PORTLET_SCOPE session attributes.
The org.apache.portals.bridges.util.PortletWindowUtils class can help out with that though.
