I am new in developing portlet application. i want to prepare a demo for inter portlet communication in which when we click a link in first portlet its effect should be shown in second portlets.But does not have any idea how to implement this, can any one help me to solve this issue or provide me any working example to overcome this issue.
Well, with JSR168, we don't really have inter-portlet communication. If portlets are in a common war file, you can share information through the application scope of the PortletSession, but that's about it.
Remember, portlets are intended to be isolated little content spots. They're not really supposed to depend upon each other for communication. For what you're doing, you might just want to have one portlet instead.
