 Post subject: Target hbm2hbmxml does not work + HQL client

Hi!

I want to generate hibernate mapping files from annotated entity classes. Unfortunately the use of the target hbm2hbmxml , which is supposed to be able to do this task, throws an exception when I use it. Does anyone know how I can get it to work?

I need to generate the mapping files because I want to use the Hibernate Tools Suite (https://hts.dev.java.net/) which can show the result of HQL Statements. Unfortunately this tool only supports hibernate mapping files and not annotations. The Hibernate-Tools plugin for Eclipse on the other hand supports hibernate annotations but we can't use it because my colleges in the support should use the tool too - and they want a simple HQL client not a complete development environment. So if anyone knows an other little, easy to use HQL client which knows how to parse annotated entites this would solve my problems too.

Hibernate version:
hibernare-3.2.2.ga
hibernate-annotations-3.3.0.GA
hibernate-entitymanager-3.3.1.GA
HibernateTools-3.2.0.beta9a

Ant target
Code:
<target name="createHibernateMappingFiles">
      <hibernatetool destdir="${build.dir}/hbm">
         <jpaconfiguration persistenceunit="${persistence_unit}" />

         <classpath>
            <!-- it is in this classpath you put your classes dir,
            and/or jpa persistence compliant jar -->
            <path location="${bin.dir}" />
         </classpath>

         <hbm2hbmxml />
      </hibernatetool>
   </target>


Full stack trace of any exception that occurs:

1) hts.dev.java.net is in Netbeans - why is that not considered a complete environment ?

2) hibernate tools just require JDT for its code completion and reflection on java info. You don't have to use all the buttons ;)

3) relying on hbm2hbmxml is not healthy, it doesn't not convert everything 100%
