Class ServletPortletSessionProxy
java.lang.Object
org.apache.portals.bridges.util.ServletPortletSessionProxy
- All Implemented Interfaces:
- InvocationHandler
- public class ServletPortletSessionProxy
- 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 PortletWindowUtils
class can help out with that though.
