Optimize JPA Entity Definition

I need someone to redesign the JPA entity descriptions for a few classes I'm using with Google App Engine so they they use fewer writes, while still supporting the types of queries I need to be able to perform.

There are three basic classes:

- User (contains as uuid)

- Session (associated with user, contains a list of events)

- Event (associated with a user and session).

I've attached the classes as they are now. I suspect the Map are the issues.

Skills: Google App Engine, Java
