Hey there, I'm using the caching mechanism in jboss with persistent entities. If you have not already done so, it might be worth migrating your application to use ejb3's persistence. There are tools out there that will assist you with converting an existing db schema to ejb3/hibernate pojos. From here it is a matter of a few annotations and xml tags to utilize the L2 cache to stop your application making excessive duplicate sql queries.
