hbm2java Nullpointer Exception

Hi,

it has taken me some time now to figure out why I was always getting a NullpointerException when starting the hibernatetool ant task (hbm2java).
The reason for the exception was simple, I had not provided a <configuration> element (as it is described as optional).
Can you just change the error message from a Nullpointer Exception to a more meaningful message (like "configurationfile parameter missing") , so that others do not need to search as long as I did?

thanks,
Stefan

i meant the latest *cvs/svn* version or nightly build if you don't want to do the build your self.

I tested it now with the latest nightly build, and the NullpointerException still occurs.

One more question: is it possible to run hbm2java without a hibernate.cfg.xml? In an earlier version of hbm2java, this was possible by just quoting a fileset dir where all hbm.xml files were situated:

Code:

      <hbm2java output="${dir.gensrc.base}">
         <fileset dir="${dir.gensrc.base}/${dir.gensrc.path}">
            <include name="**/*.hbm.xml" />
         </fileset>
      </hbm2java>

Now this does not seem to be possible anymore (unless I am missing something). The error message is:

"Class org.hibernate.tool.ant.Hbm2JavaExporterTask doesn't support the nested "fileset" element."

This is a bit of a nuisance because my hibernate.cfg.xml File is not in the same project as the *.hbm.xml Files.
