portletRequest.getPortletSession() returns null

[9年前 に Rafael Rodrigues によって更新されました。]

In my project, I want to use Liferay Login to autenticate the users, for that, I developed a hook that adds functionalities to the liferay login, the rest of the project is adapted from a one previously developed for IBM websphere and its located in another war file.

I guess there is no problem, but this project requires some login information saved in PortletSession, like the userName, sessionUuid...

I tried this:

	PortletRequest portletRequest = (PortletRequest) request.getAttribute(JavaConstants.JAVAX_PORTLET_REQUEST);
	PortletSession session = portletRequest.getPortletSession();
	session.setAttribute("TEST_PORTLET_SESSION", "GOT_THERE", PortletSession.APPLICATION_SCOPE);
	session.setAttribute("webtoolPortlets."+"sessionUuid", session.getId(), PortletSession.APPLICATION_SCOPE);

but it returns null for the PortletSession.

So my question is: How do I transfer this information from the plugin to the application PortletSession?

Thanks in advance!

First, this thread has nothing to do with your request, you should have started a new thread...

That said, application scope only works between portlets in the same war file. if you are in different wars, then you need a completely different mechanism. I'd suggest cookies for client side or database for server side.

you can try the following -

PortletSession portletSession = renderRequest.getPortletSession();  
portletSession.getAttribute("param1" ,PortletSession.APPLICATION_SCOPE);

I think David already explained that APPLICATION_SCOPE only works when plugins are in the SAME war file. The original post states that he has more than one war file, so APPLICATION_SCOPE won't help here.

i think, you can try for IPC mechanism
