how can i put my hibernate.cfg.xml and other hbm.xml files in to jared file

I used zipfilesets to include the hibernate jar and associated jars in my application jar. Here's my build.xml that I run from within eclipse:

<?xml version="1.0" encoding="utf-8"?>

<property name="jarFile" location="${jarDir}/mainapp.jar" />

<!-- Set up the class path for compilation and execution -->
<path id="project.class.path">
<!-- Include our own classes, of course -->
<pathelement location="${classDir}" />
<!-- Include jars in the project library directory -->
<fileset dir="${libDir}">
<include name="**/*.jar" />
</fileset>
</path>
