Hi Subrat,

To share session attribute between different portlets you can make use of following property

session.shared.attributes=COMPANY_,LIFERAY_SHARED_,org.apache.struts.action.LOCALE,PORTLET_RENDER_PARAMETERS_,PUBLIC_RENDER_PARAMETERS_POOL_,USER_

To set attribute -

actionRequest.getPortletSession().setAttribute("LIFERAY_SHARED_session_attr", "Value",	PortletSession.APPLICATION_SCOPE);

To get attribute -

actionRequest.getPortletSession().getAttribute("LIFERAY_SHARED_session_attr",PortletSession.APPLICATION_SCOPE)

HTH

I hope This code may help you to understand IPC pls Find the attachment.

Please do not refer to this as IPC, because it's not.

IPC, in the portlet world, has a specific meaning and is based upon events and listeners at the portlet level.

All you've done in this code is set a variable in the portlet session's application scope. This is nothing more than sharing data, and is very much bad practice (want to change the portlet key? Have to touch all of your code that's using it).

I agree with David. This is just session sharing.

Please refer this link

NOTE : In the given link also they are considering session sharing as IPC, which is not correct.
