The capability of portlets to exchange information (also called inter-portlet communication or cooperative portlets) is powered by the property broker in WebSphere Portal. The WebSphere Portal V18.104.22.168 property broker does not support inter-communication between IBM portlets and JSR 168 portlets because they run within separate portlet containers. This article shows you how to write a custom portlet service to enable legacy IBM portlets and JSR 168 portlets to share information as properties. You also see how to manage the life cycle of a shared information property in a distributed environment, using the dynamic WebSphere Application Server caching feature. To get the most out of this article, you should have a good understanding of Java portlet programming and a basic understanding of the WebSphere Portal portlet service feature. See Resources for links to information that can help you get this foundation.
