Do you mean this:
Hibernate Certification?
Note that this has nothing to do with people getting certified with Hibernate in the same way as
SCJP makes you a certified
Java programmer. Instead, it is about getting software certified - if a particular piece of software is certified for Hibernate, then that means there's a guarantee that it works well with Hibernate.
Because this does not have anything to do with SCJP, I am moving this
thread to the Object Relational Mapping forum, where Hibernate is one of the subjects.
