Java EE is a big hammer, it's got everything you could possibly ask for. You used to pay for this by requiring huge config files. Ejbs for example allow access from remote servers to objects as if they were local Objects. This can be used to separate out general application logic from the web, native application, web service interfaces which can be run on there own dedicated servers all communicating with the backend transparently via ejb. Any operations in a ejb are automatically transaction with the database. Ejbs used to be a configuration nightmare though, but not anymore. Java play is the get it done platform. They both have their uses.
