To display the html report in New Window, I have set the attribute in a servlet. I am using the following command to open the New Window:

Applet.getAppletContext().showDocument(new URL(UrlAddress), "_blank");

In another servlet, I like to retrieve the attribute value to display it.

HttpSession session = request.getSession(true);

String htmlReport = (String)session.getAttribute("REPORT");

I cannot get the attribute value since session always returns the new session id.

Here is Context.xml:
<!-- The contents of this file will be loaded for each web application -->
<Context cookies="true" crossContext="true">
   <!-- Session persistence is disable by default. To enable for all web
   apps set the pathname to a non-empty value:
   <Manager pathname="SESSIONS.ser" />

   To enable session persistence for a single web app, add a
   WEB-INF/context.xml
   -->
   <Manager pathname="" />

   <!-- Install an InstanceListener to handle the establishment of the run-as
   role for servlet init/destroy events.
   -->
   <InstanceListener>org.jboss.web.tomcat.security.RunAsListener</InstanceListener>
    <SessionCookie path="/" />
</Context>

How can I retrieve the old session id?

Thanks
