ORM Frameworks

I do not have any experience with any OR mapping libraries, so I plan
on learning some. (My company is not exactly cutting edge.)

What is the status of OR mapping tool utilization in the Chicago
market? I assume Hibernate is used a lot. What about iBatis or JPOX?
Or can I just stick with Hibernate and leave it at that?

I work for Red Hat and JBoss. I see a lot of
Hibernate...very little iBatis and no JPOX...in the
year I have been talking to customers. 200+ different
data points.

Thank You

Hibernate is probably the most popular. We use only JPOX since we
also work with object databases when possible.

I work for a manufacturing company where we have several Java apps ranging in small-medium-high complexities in nature. We have hibernate as O/R mapping as the standard.&nbsp;Looks so far so good ..

Exactly what to use might depend on your motivation for moving to an ORM framework, which you did not say.

That aside, your best bet is to develop against an implementation-independent persistent API, such as the JPA, or JDO, which Hibernate (for example) implements. That way, in the future you can move to a better implementation without rewriting your application.

Obviously it depends on your needs.&nbsp; Hibernate is very complete, very abstract, you can generally keep your code completely at the object layer and never need to worry about the database or SQL.  iBATIS takes a different approach, by giving you direct, fine-grained control over the SQL queries sitting behind your objects.&nbsp; I've heard very positive feedback about it from developers who are using it; they like how light-weight and straightforward it is.

It&#39;s also worth considering what your integration needs are.  If you're going to do JPA stuff, those specs were pretty much written by the Hibernate, err, I mean EJB3 expert group so Hibernate would be the path to take. ; If you're using Spring, there is good integration with Hibernate, iBATIS, JDBC, and lots more.

I think this is a good point. You may not be able to do everything with
the standard API(such as JPA annotations) that you can do with the
vendor's native API(such as Hibernate annotations), but if you avoid
using the vendor API wherever possible, you keep your porting options
more realistic.
