Lucas Jellema has written an article called "Getting Started with EJB
3.0 Persistence out-of-container using the Reference Implementation
(GlassFish) <
http://technology.amis.nl/blog/?p=962>," which shows
step-by-step how you can use the reference implementation to persist
data with EJB3.0 persistence, including a service class and a data model.
It's good to see people documenting their experiences with the various
containers; now we need to start seeing use cases and things that
/don't/ work with EJB3, so we can start building guidelines for when it
should or shouldn't be used.
Merry Christmas
