One neat option with DB objects is to implement the design for a FilteredRowSet as specified by Sun's RowSet. It is/can be separated from the DB for caching in the application or session and it essentially acts like a mini-db in memory. One use would be to select * clients and then allow users to use 'range' or 'like' filters to control the cursor of the RowSet.
I tried going down the road of object caching but I cam to the conclusion that any data that required caching was better off just being cached at the view level or pre-view level as XML or as the static page content (OSCache). Retaining ACID properties of site when multiple applications were using the same DB wasn't worth the hassle. A good DBCP provides excellent speed anyways.

We implemented our own full object cache for an industrial control system that we are writing. I would be very interested to hear any experiences that folks have with the products mentioned here.
