Julien, I did few work around and able to do Page to page communication with few parameter as string. Here is the relative url i have put inside achor tag <a href="<%= childURL.toString()+"/DestinationPortletWindow?action=2&myparameter="naresh"%>"><%= childName %> if you see the href part of the above anchor tag childURL: is a PortalNodeUrl of the destination page(PageB). DestinationPortletWindow: is name of the window which doView() is going to execute. action: is parameter which diffrenciate between the RenderRequest or ActionRequest. if action =1 , this url is going to call processAction() if action =2, doView() is going to call. In this case it is going to call doView(). myparameter: is the parameter you want to send to the destination portlet. if you want more parameter , append parameter to end of the url. get the parameter in portlet as renderRequest.getParameter("myparameter")/actionRequest.getParameter("myparameter"); But still it has few limitation: 1. I can not pass the object other than the string in this way. 2. I have to get destination Page url on PageA.
