Extend your Persistence Unit on the fly

Imagine a system that keeps track of player statistics in a sports league. Personal information such as name, height, weight and basic statistics such as the number of games played is stored for all players.

A persistence unit is deployed with all the mappings described above.

The system admin of a basketball league wants to use the system and add mappings for points scored and fouls. As the system is running they tell EcliseLink about mappings for those fields and the next EntityManager they get uses them.

Welcome to our new committer, Mitesh Meswani

I want to welcome Mitesh Meswani of Sun Microsystems who has just joined the EclipseLink project as a committer.

Mitesh has been working with us on the EclispeLink code base since the beginnings of the Java Persistence API. Most recently, he has been helping us get our distribution to a state where it is easier for people using maven to consume. In the past he wrote our Derby/JavaDB support, added code to allow us to automically detect what database is being used, and provided a number of complex bug fixes.

Welcome Mitesh, we are excited to have you on board, (more...)
