Caching is not a silver bullet. You need to analyse your application and your data access patterns and make sure you are applying caching where it can and will help. I have actually seen systems with so many layers of caching (DB, JDBC driver, ORM framework, application, front-end, etc etc) that removing a lot of the caching actually made things a lot faster. Especially with an ORM framework/JPA, you should look at the access patterns of your data. Caching may help overall performance with some entities, and not at all with others.
