Class SessionData

java.lang.Object

org.openxava.util.SessionData

public class SessionData
extends java.lang.Object

To access session data without having access to HttpServletRequest or HttpSession.

It has to be used from inside an OpenXava request, though you can use it in any part of your application: JSPs, actions, calculators, validators, entities, etc.
If you want use it inside your own servlet you have to call first to SessionData.setCurrent(request), and SessionData.clean() at end.
An advantage of using this class over direct request.getSession() is that it abstracts your code from web technology, so that code could work in other contexts, as Swing for example.
