Explain about PortletContext ?

The concept of a portlet context is similar to a servlet context: it provides access to
the environment in which the portlet is running. In the case of portlets, the environment
is the portlet application to which the portlet belongs, and the portlet container
in which the portlet is running.


Portlet applications are extensions of web applications, so in portlet applications
the PortletContext and ServletContext objects coexist.

A single PortletContext instance is associated with a portlet application, and it’s used by portlets to access resources in that application (which could be a JSP, servlet, or other portlet).
