This is what i got from googling... FROM AN ARTICLE "TopLink is fast, nimbly maps complex relationships, and provides both EJB-like and nearly transparent Java models. But Oracle recently acquired TopLink, and Oracle is regrettably both a database vendor and an application server vendor. If you're a WebLogic customer or use a non-Oracle database, you're going to want to think long ...

30. Toplink vs. Hibernate thread on OTN    forum.hibernate.org

Heehee, the Ken Auer guy is amazing. He went and completely bastardized Hibernate 'cos he decided he needed process-scoped identity. Then he blames us 'cos his bastardized Hibernate doesn't work.
