Actually that article just compares iBATIS and Hibernate,  and it
doesn't do a very good job.

Hibernate implements JPA.  I've maintained several different projects
that use it.  I've also tried to use it for some new projects,
without success yet.  I've never touched a project that used
Hibernate's JPA support;  they've all used the native Hibernate API.

TopLink and eclipseLink seem to be two different forks of the same
project,  both based on an old Oracle-specific "TopLink" product.
They both implement JPA.

If you can express everything you need to in JPA,  I imagine it would
be good to use that and then have the flexibility to switch between
Hibernate or TopLink depending on which performs better;  but I've
never written code that could do that.
