What exactly do you want to achieve?

There's a bit about session in the Book of Vaadin. Usually the developer doesn't have to ponder much about session, sessions timeouts are probably the biggest concern.

basically what i am trying to do is some permission checking, i want to be able to check the permissions of the user in the current session, etc

What you are looking for is the ThreadLocal pattern. Store your application's current user in a ThreadLocal variable.
