This article describes, and shows how to use, a portlet service to extend the caching options available to portal application developers. The expirable properties portlet service (hereafter called EPPS) works as a central caching system for portlets running under IBM® WebSphere® Portal. You can use it to improve the performance of portal applications, by caching elements used within a portlet. The EPPS provides dynamic, fine-grained control of items to be cached. This article includes the code for this portlet service, and a sample application which illustrates how to use it.
