Java Forum / General / January 2008Hibernate or JPA?
Hi, I am working on a project that involves the use of a database. I would like to use ORM and my initial thought was to use Hibernate. Meanwhile I started looking at EJB3 and notices the Java Persistence API... I don't have much experience with Hibernate, and also didn't use the JPA before... I would like to get some oppinions on which one is better and why from people who have used Hibernate and/or JPA before. Thank you in advance!

Hibernate *is* an implementation of the JPA specification. However, it also pre-dates JPA, so there are other ways in which you can use it. OpenJPA (http://openjpa.apache.org/) is an alternative JPA implementation. Both have their quirks and bugs. I have mostly used Hibernate, but decided to go with OpenJPA on my most recent project. Hibernate's dependencies are a bit of mess - there are 3 separate downloads required to use JPA and you have to consult the matrix to determine which versions of each can be used together. OpenJPA is more focused since it doesn't support non-JPA modes of working (there is only one download and fewer library dependencies). Dan.

OTOH, if you use Hibernate's JPA implementation as part of a JEE container (e.g. JBoss) you usually do not need to worry about those issues because JBoss team has taken care of this already.
