Creating a Postprocessing Action Class

The com.sas.portal.portlet.PostProcessorInterface is available for implementing activity that should occur when a local portlet is no longer on display. Like other parts of the portlet architecture, it must be defined in your XML file. You can use the post-processor phase to free resources that you attached to in the portlet initializer. You could also remove HttpSession attributes that were set in the initializer or action. This is especially important to consider because multiple copies of your portlet could exist on other portal Web application pages or even on the same page.
