I've posted this in the beginner's forum, but maybe it better belongs here: I need to integrate my JBoss app's authentication with a separate Ruby on Rails server. I've setup a servlet that takes a jsessionid as a query parameter, and returns a message saying if that jsessionid is authenticated (logged in). But I'm stumped as to how to find the HttpSession object for a particular jsessionid. It seems like it was very easy to do in previous versions of JBoss: in any servlet obtain the session context, the get the session according to jsessionid: HttpSession s = request.getSession().getSessionContext().getSession(JSESSIONID); However, this has been 'deprecated with no replacement.', and getSession always returns null. I haven't yet found an explanation as to why this was deprecated. I've read people suggent implementing a SessionListener, then recording the information I need in some kind of global variable myself. However, since I'm working with a clustered JBoss, I'd then need to make a JBoss Cache instance to share it -- and then it seems like I'm just recreating what the JBoss session management does by itself! I know the information is there in JBoss -- I just need a way to get to it! Any help much appreciated. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4161623#...
