Hi All,

I am getting the a error while converting .hbm files to POJO using the following build.xml file.

<taskdef name="hbm2java"
classname="net.sf.hibernate.tool.hbm2java.Hbm2JavaTask"
classpathref="pojogen.classpath"/>
<hbm2java config="codegen.cfg.xml"
output="${build.gen-src.dir}">
<fileset dir="${hbm.xml.dir}">
<include name="**/*.hbm.xml"/>
</fileset>
</hbm2java>

Error :
