Well, in fact there are three ways to use getSession(), a 'default' one plus a method that takes a boolean as input indicating whether to explicitly create a Session or not. Normally, one would use the default implementation (getSession()). This will either return a reference to the Session if one already exists, _or_ create a new one and return a reference to that (lic: Singleton pattern). In both cases, after calling getSession(), a valid Session instance should exist. If you pass an additional boolean parameter to this (overloaded) method, you can control session creation behavior on your own. So if you just want to check if a request already belongs to a Session, you pass 'false' and then check for null being returned (or the other way round). If you want a new Session to be explicitly created each time, you pass 'true'. You can easily get these details from the API docs, just to note.
HTH, -- Chris (SCPJ2) NB. I said I never tried, but looking for JSESSIONID (still wonder if this is correct, could be some '_' goes some- where; but then, I might be mixing this up with form-based login) would be my first approach for session-enabling the GUI thing. Thought I made that somewhat clear before.
