To make sure I'm not missing something with the 3.x Tools. If I want to author my POJO's, and then generate mappings and ddl, XDoclet annotations will have to be what I use, correct?

I see Hibernate Tools that support the other direction (author the ddl, generate the mappings and POJO's), but I don't see a Hibernate Tool to go from POJO's to mappings and ddl.

Makes sense for Hibernate not to spend time providing that if XDoclet works well. I just wanted to make sure that that people weren't migrating away from that like they are for Middlegen since Hibernate Tools now does that stuff for you.

Thanks.

You basically have two options when starting from POJOs;
1) XDoclet - I use it for a reasonably large application that I have been building. There are two versions to choose from; XDoclet 1.3.x and XDoclet 2. Both have good support for H2 and reasonable support for H3.

2) Use annotations - This works very well, requires H3 and Java 5. You can choose to restrict yourself to JSR 220 markup and thus be portable (not that you would want to move from HIbernate :-)).

Thank you sir. If I go the EJB3 Annotations route, what's the documentation like? I saw the simple example on the Hibernate site (http://www.hibernate.org/247.html), but is there comprehensive documentation out there describing the things I'm used to working with in terms of XDoclet (one-to-many, many-to-many, lazy loading, yada, yada, yada)?


Thanks again.

HIbernates implementation is under the EntityManager sub-project
http://www.hibernate.org/299.html

This is tracking the standards. If you goto the documentation you will see an annotations section and a EntityManager section both have the information necessary to move forward, eg, for associations, see
http://www.hibernate.org/hib_docs/annotations/reference/en/html/entity.html#entity-mapping-association

There are links to samples, eg, JBoss Trailblaser tutorials and demos.

Hope you find this is a good start.

Again...thank you very much for the prompt response. You have been very helpful.
