Hi All,

JPA.

OpenJPA is compliant with the latest Java EE specification, which
includes JPA, OJB is not.

Apache OBJ was last updated nearly 3 years ago. OpenJPA was last
updated nearly 3 months ago.

From what I remember of JDO, JPA is a much easier model to which to
program.

Did you look at the OpenJPA web site?

Hi Lew,
yes I gone through http://openjpa.apache.org/ but there I didn't found
any comparison there with OJB.
Could through some light or provide some link where I can found
comparison.

Thanks in advance

Fundamentally they're different. OJB implements the defunct JDO standard and
OpenJPA implements the current JPA standard.
