Hi all! I use "jboss-4.0.5.GA" and EJB3.0. My client is standard alone. I use DatabaseLoginModule to authenticate a particular client. When the client login success, I can get some informations such as username and role. Can the server maintain connection between clients and server ? How server can recognize that a particular client has logout (disconnect). have some ideas ? Thank. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4098215#...
