Hi guys, I'm looking for an O/R mapping free solution. I know so far about Castor JDO and Hibernate. If you have any info on this subject and maybe some reasons why one should be used please share it with me. Thanks a lot, Sergiu.
Hibernate is by far the more popular of the two. Besides, Castor JDO is not really JDO-compliant so you're not gaining anything by that. I would make the decision between Hibernate and some JDO-compliant product (such as the open source TJDO) instead.
