Here is my ant task:

<target name="generate-mappings" depends="compile"\

<hibernatedoclet
destdir="${build.database.classes.dir.map}"
excludedtags="@version,@author,@todo,@desc"
addedtags="@xdoclet-generated at ${TODAY},@author"
force="true"
mergedir="${package.src.dir}"
verbose="true">
<fileset dir="${build.database.classes.dir.map}">
<include name="**/*.java"/>
<include name="exceptions/*.java"/>
<include name="dao/*.java"/>
</fileset>

<hibernate version="2.1"/>

<jbossservice ..../>
</hibernatedoclet>
</target>

This task runs, says it creates the mapping files, creates the jboss-service.xml and completes successfully. BUT, there are no mapping files in the build.database.classes.dir.map directory? What is going on? I have tried everything I can think of to include putting a . in front of the files in the include names. Changed the hibernate version to 2.0. My environment looks good. Any clues???????????

Maybe you environment is not setting the variables. Try hard coding the ${build.database.classes.dir.map} values rather than use the properties. In anycase, try find an example package from one of the number of tutorials or example applications around.
