According to my understanding the hbm2java-tools from hibernate-tools are made to generate Pojos on the basis of a jdbcconfiguration, that is reverse enginereering database-metadata. This is what I read from the tools-docs.
Or is this wrong?

What I need is a "real" hbm2java: generate java-Pojos from a set of hbm-files. Additionally I need to specify a "strategy" and custom templates to render the java-code. Either from Eclipse console OR as ant task.

Can someone advise me if this is possible and where appropriate docs are located.

Thanks.

Yes, it's possible, both from Ant and from the Eclipse plugins. http://www.hibernate.org/hib_docs/tools/

this is what I referred to, of course.

Ok, but it says I need to pass a hibernate.cfg.xml.
Is it possible to specify there a set of hbm-files which will be rendered to Java-Pojos? Or how else do I pass the hbm-files as a resource?

eh - what is wrong with listing the mappings in your cfg.xml or simply use ant and use a fileset ?

And yes, hbm2java can generate code from a JDBCConfiguration but it can do the same for a normal Configuraiton and a AnnotationConfiguration....polymorphism you know ;)

well, I tried to pass the hbm like this

<mapping resource="Aufbau.hbm.xml"/>

but then I ran into trouble with the path. It can't find the file
What is the reference directory that is used to find the resource?

a resource is not a file - they are looked up via the classpath
