My application use DatabaseLoginModule and JAAS. I write a login form (standalone application) to client can enter userName and passWord. And after client login successful, he can call some methods on beans. Example: LoginContext lc = new LoginContext("client", loginForm); | lc.login(); | ...My works here... ---> call some methods on beans | lc.logout(); My mind is if he login successful, and he do nothing and 10 minutes later, he will logout automatically (same as window system). I thanks for some your relplies, it's very usefull ! Sorry, my E is not good. Expect some guides from you ! catania.
