Auditing Unique Oracle Users

We are using WebSphere for the application server and Hibernate for connection pooling. The applications are written in java.

One of the problems with this configuration is that the users authenticate to the application and are then connected to the database from an application account.  Auditing this database is useless because we really have know idea who is doing what. It is all through the application.

Has anyone had any success auditing unique user IDs when the user actually logs in through an application?
