I want to generate my persistence classes using Hibernate tools as EJB3 entities.

I tried using seam "generate_entities" to generate my persistence classes for Oracle 10g DB . I assume behind the scenes they use hibernate tools to do this.

Everything works fine, But I have a question here. Is there any way that the Table and Columns comments can be incorporated as Class and Attribute commments in the generated classes. I am seeing this Comments as part of generation in the console. Is there anyway these comments can be incorporated in the respective classes ?

Also is there is any ant task as part of seam that I can incorporate in my build.xml?

1) we don't put the comments from tables into the model since there isn't a one-to-one mapping...you can adjust the templates to do so if you wish.

2) ant tasks - read docs on tools.hibernate.org

Thanks max, Can you provide me any pointers/ideas to adjust the templates.

Look in the docs at tools.hibernate.org and look at the templates in hibernate-tools.jar is the best resource.
