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 V188.8.131.52 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.
