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.

Note: If an APPLICATION_SCOPE session attribute is going to be stored with a name which does not start with a wicket prefix (look at WebApplication.getSessionAttributePrefix(org.apache.wicket.request.http.WebRequest, String) ) then the attribute will be stored normally as APPLICATION_SCOPED session attribute and this attribute will be accessible from every wicket portlet.
