Hi Alex,
The following link explain the session handling,
http://wiki.orbeon.com/forms/doc/developer-guide/xforms-with-java-applications.
Where one of the statement says that,
Always create a session in your code, e.g. with request.getSession(), even if you're not going to store anything in that session.
I need the same way, I don't want to store any thing in the session. But I need to get the session default info.
How can I use request.getSession() method?
