I had the same conclusions about these implementations. OpenJPA was/seemed buggy Hibernate had tons of libraries and seemed to have trouble with not lazy loading everything. Toplink ended up as my choice. It was not as flexible as Hibernate would have been but it works and I don’t have to install commons-logging. The one I … Read more
