Usertracking

Hi,

is there a popular solution for usertracking in the J2EE context? I can implement my own filter, but i am sure that i am not the first one who want to track the users of the website. It will be great if somebody can tell me an open-source usertracking solution which implements a servlet filter.

Thanx for any reply,

Udo!
