Inter-portlet communication using PortletSession

[louise_za]

Hello

I am trying to get IPC working between 2 portlets. So far I have the following:

In the processAction methos of portletA I have:

PortletSession ps = aRequest.getPortletSession();
ps.setAttribute("id", id, PortletSession.APPLICATION_SCOPE);

In the doView method of portletB I have:

PortletSession ps = rRequest.getPortletSession();
String object = (String)ps.getAttribute("id", PortletSession.APPLICATION_SCOPE);

I can access the 'id' variable here. I would like to access the id from the jsp that is associated with portletB but have not been able to get that right. I have tried:

In jspForPortletB:

String object_id = (String)request.getAttribute("id");

but I get a null value back. Does anyone have a suggestion as to how I can get the id value in the jsp? I have read in the Portlet Spec that a value stored in the PortletSession should be available in the HttpSesssion.

Shouldn't you be doing getSession().getXx on the request in the jsp instead of looking at the request attributes?

Thank you thomasra! That solved the problem.

Solution code:

String test = (String)request.getSession().getAttribute("id");
