Hi,

I'm having an error when I tried to use the tool hbm2java.
I've created a target in ant and here's the result :

The target :

<path id="hibernate.tools.classpath">
 <pathelement path="${hibernate.tools.dir}/hibernate-tools.jar"/>
 <pathelement path="${hibernate.tools.dir}/lib/jdom.jar"/>
 <pathelement path="${hibernate.tools.dir}/lib/velocity-1.3.1.jar"/>
 <fileset dir="${hibernate.dir}/lib">
   <include name="**/*.jar"/>
 </fileset>
</path>

<target name="hbm2java"
    description="Generate .java from .hbm files.">
 <taskdef name="hbm2java"
    classname="net.sf.hibernate.tool.hbm2java.Hbm2JavaTask"
    classpathref="hibernate.tools.classpath"/>
 <hbm2java config="${config.dir}/hibernate/hbm2java.xml"
    output="${javasource.dir}/java">
    <fileset dir="${javasource.dir}">
      <include name="**/*.hbm.xml"/>
    </fileset>
 </hbm2java>
</target>

The error :
