Logging for one session

Question

I'm using java.util.Logging mechanism for logging in my web application. I always use logger via class name - e.g. Logger.getLogger(MyClass.class.getName()).log(....)Now, I wonder if there is a technique or best practice to show only log records for one user session.
For example.. I have a servlet that after receiving request creates one thread, which creates n-threads to get some data from different web services. Naturally there can be many concurrent users using this servlet. I would like to use logging mechanism to show log records only for particular user (session).
The only solution that came on my mind is to put sessionId into all threads names, create custom Logging handler that puts thread name as record parameter and then filter out records that contain parameter with chosen sessionId.
Is there a better solution?
Thanks.

Hi Gus,
One of the things getting logged is the session id.Do you mean the database session id or the Apex session? The database session id changes when a different session is used in the pool. The Apex session doesn't change until the user logs out.
So we set an application item to the value of the session id during authentication.You don't need to do this. The database session can be found in the user context using SYS_CONTEXT('USERENV', 'SESSIONID'). The Apex session is available using V('SESSION'), it is also can be found in the user context, together with the Apex username using SYS_CONTEXT('USERENV', 'CLIENT_IDENTIFIER'). So you can get the session ids from the context when you log information.
