Portal and Portlet Configuration

The portlet API defines several interfaces for working with preferences and settings for the portal, the portlet application, and the current user of the portlet. Portlets access information about the portal that they are currently running in through the PortalContext object. The configuration settings for the application are available from the PortletConfig class. The portlet accesses and persists individual settings and preferences transparently with the PortletPreferences object.
