Although not an in-depth report: I've used Hibernate, NHibernate, and OpenJPA. I found the Hibernates to be easier to use and less prone to errors. It also offers functionality that isn't offered in OpenJPA (such as an IsDirty method) and the CASCADE options are smarter in Hibernate. Also the portability to NHibernate makes it that much easier if you develop onm multiple platforms.
Personally I only use OpenJPA when I must (i.e., when it's been decreed or when maintaining an existing project). - Marc -----Original Message----- From: Rick Hightower [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 20, 2008 1:18 AM To: [email protected] Subject: Why would I choose OpenJPA over Hibernate? http://java.dzone.com/news/hibernate-best-choice Has anyone done a comparison of Hibernate versus OpenJPA that compares ease-of-use, caching, tool support, legacy integration, etc.? Perhaps such an internal report was used to decide which ORM tool to pick. If so, what were the results? http://java.dzone.com/news/hibernate-best-choice --------------------------------------------------------------------- This transmission (including any attachments) may contain confidential information, privileged material (including material protected by the solicitor-client or other applicable privileges), or constitute non-public information.
