Other groups are moving very fast too.
Hibernate supports JPA
and BEA's Kodo is also in good shape.
The Apache community is also moving in that direction;
they seem to be lagging a bit but I expect them to move quickly soon
The extra, and important, benefit of JPA is that it is possible to Mix and Match.
We have already started testing the GF RI with other containers, and other JPA implementations
All this creates an ideal situation for the customers, and
I expect a move towards replacing the Hibernate-specific dependencies
with standard-based, JPA, dependencies, as described in
Spring and JPA
Roller and Hibernate.
And new applications,
like NetBeans and CRUD,
are all written against JPA.
Interesting times ahead!
