Daniel Pocock commented on HBX-713:
-----------------------------------

I've written a patch for this, but unable to compile Hibernate tools:

a) build.sh mentions ../hibernate-3.1, should be ../hibernate-3.2

b) The following errors are reported by the compiler, using version 10233 from SVN:

   [javac] /home/daniel/ws/hibernate/HibernateExt/ejb/src/java/org/hibernate/ejb/AbstractEntityManagerImpl.java:584: cannot find symbol
    [javac] symbol  : constructor OptimisticLockException(<nulltype>,org.hibernate.HibernateException,java.lang.Object)
    [javac] location: class javax.persistence.OptimisticLockException
    [javac]                             throwPersistenceException( new OptimisticLockException( null, e, entity ) );
    [javac]                                                            ^
    [javac] /home/daniel/ws/hibernate/HibernateExt/ejb/src/java/org/hibernate/ejb/instrument/InterceptFieldClassFileTransformer.java:23: cannot find symbol

    [javac] 2 errors

> We use hbm2java to create EJB3 entity beans from hbm files.  It would be really useful to use the `meta' element to insert additional class level annotations.  Is someone already working on such a feature, or should I submit a patch?
> Here is an example of what I would like to do:
> <meta attribute="extra-import">org.jboss.seam.annotations.Name</meta>
> <meta attributre="class-annotation">@Name("myObject")</meta>
> such that the following code would be generated:
> import javax.ejb.Entity;
> import org.jboss.seam.annotations.Name;
> @Entity
> @Name("myObject")
> public class MyObject ....
