Annotation support in Hibernate3.0a

jgongo · **Joined:** Wed Oct 08, 2003 6:34 am **Posts:** 29

In the roadmap they mention support for JSR-175, and I have found some mails in the dev list talking about Java annotations support in Hibernate as an alternative for mapping files. Is this support available in Hibernate3.0a? Is there any way to test/use this functionality right now?

Best regards
Jose

Where can I find it? I have checked the web, , the hibernate3.0 jar and files in sourceforge...

Thanks, regards
Jose

As far as I know it isn't supported, in the 3.0 alpha version anyway. Or, if it is, it isn't documented yet.

You might want to take a look at the EJB 3.0 preview that is available on JBoss's Web site. Their implementation of EJB 3.0 entitiy beans is based on Hibernate and uses annotations.

I know the risks of making such a question, but...

any planned release date?

I don't see annotations mentioned in the docs in the latest CVS version, so, I'm guessing that now is a little too early to try to get that working...

The next H3 release will be beta 1 and there will be a alpha release of annotations. Very soon - see development list for discussions.

Actually, it's already usable. I'm only working on minor better support of the EJB3 spec.

So, are the annotations Hibernate specific annotations, or, are they just the EJB 3 annotations? I still don't see any documentation for them. Am I missing something, or, is that going to be in a different download?

Right now I covered EJB3 annotations only, since EJB3 match 95% of real life cases. The goal is to be EJB3 compliant and add specific ones for uncovered features.

It will be in the HibernateExt download, I think.
For now just take HibernatExt from CVS and check the metadata package
The early doc is here http://cvs.sourceforge.net/viewcvs.py/hibernate/HibernateExt/metadata/doc/tutorial/

Thanks for the info, much appreciated. Does this mean that you can use EJB 3 Entity Beans without an application server? i.e. I can use it in a standalone application and I don't need JBoss?

emmanuel · **Posted:** Fri Dec 24, 2004 12:34 pm

Yes. You can use the ORM related annotation and API outside of a container.

Awesome, looking forward to it's release...

I want to make sure I understand this. EJB 3.0 support has been added to Hibernate (IE the JBoss implemention and standalone) but not to the Extension correct? In other words is it possible to automatically generate EJB 3.0 code with hbm2java ?

Thank you.
