Re: Sharing session between portlet and servlet

The key of your question is "in a other context"

Portlets and Servlets in the same webapp can share session attributes placed in the session by the portlet in the APPLICATION_SCOPE. There is no provision in the portlet API for sharing session attributes between webapps.

Hey, I've a problem to share session data from a portlet with an servlet (in a other context).

An example, in portlet1 i put (or try to put) an attribute into the httpsession:

		PortletSession ps = PortletActionContext.getRequest().getPortletSession(true);
		String poco = (String)ctx.getAttribute("poco");
		if (poco == null) {
			System.out.println("poco == null!");
			ps.setAttribute("poco", ""+1);
		} else {
			int newLoco = Integer.parseInt(loco);		
			newLoco++;
			ps.setAttribute("poco", ""+newLoco);
			System.out.println("poco rules: "+newLoco);
		}
I also tried to use the overloaded method of setAttribute (ps.setAttribute("poco", ""+1, PortletSession.APPLICATION_SCOPE) and ps.setAttribute("poco", ""+1, PortletSession.PORTLET_SCOPE)) without success.

In a servlet, i try to read out my http session (HttpSession sess = request.getSession(true) ...) but I never find my variable poco in the http session. The only thing that worked was using the portletcontext:

		PortletContext ctx = PortletActionContext.getPortletContext();
		String poco ...

But in this case, the scope of the session variable was just portlet-wide (portlet wide=all portlets, which are in the same .war file / defined in portlet.xml).

Some more information about my env.:

I'm using:
- springframework 2.0.8
- struts 2.0.11.2
- pluto 1.1.6
- hibernate 3.2.1.ga

Tomcat v6.0.14

Server.xml
    <Connector port="500" maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" redirectPort="14443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true" emptySessionPath="true" />

    <Context path="/customer"
               docBase="c:/whatever/blah/"
               crossContext="true" />
