How to monitor J2EE active user sessions?

Users login to a Java Web Dynpro application that requires explicit login.

How the system administrator can monitor the active users of a pure J2EE engine?

In ABAP this is available via transaction SM04.

It seems that Netweaver Administration ( /nwa ) does not provide the same.

Any idea? Thanks a lot.
