Sharing session attribute between servelt and portlet

[sbiwal]

Hi I am working with JBoss Portal 2.6.2, deployed with JBoss AS 4.2. I have the following situation -

A thirdparty class calls a servlet (myServlet). Now this servlet should update a portlet (myPortlet) based on the parameters sent by the thirdparty class.

In the doGet fucntion of myServlet I set the parameter received as a session attribute by -
request.getSession().setAttribute(param, value);

However when I get to the doView function of the portlet, this session attribute is lost.

If I try a vice-versa scenario (setting attribute in Portlet and then reading from servlet) it doesn't work either !!!

Please help !!

I read that you cannot share data in session between two different war files.

I don't know if this explained it - I never tried anyway.

Sharing session data indeed only works for portlets and servlets bundled in the same web application (war file).

I think the problem here is that the name of the param is namespaced for the portlet so if you set a param called "foo" in the portlet session, you cannot access it using just "foo" in the servlet. Please look at the servlet specification for the namespace format.

So, in short what is the name space chosen by jboss portal to register parameters in the global session?

Try using APPLICATION SCOPE to retrieve the session attribute in your portlet code.

request.getPortletSession().getAttribute("foo", PortletSession.APPLICATION_SCOPE);

Thanks. I had started using the APPLICATION_SCOPE and it worked.

Hello,

How I can access the session attribute value ( set using

renderRequest.setAttribute("MainCommand", renderRequest.getPortletSession().getAttribute("commandType", PortletSession.APPLICATION_SCOPE));) from jsp page
