primark key for entity bean through ejbdoclet

[mridul das]

We aare using ejbdoclet to generate remote, local, home interfaaces and descriptors for our ejbs. For the entity bean however the primary class is not getting generated and also the <prim-key-class>int</prim-key-class> in the ejb-jar.xml shows int instead of the expected class .
this is the ejbDoclet task.
<target name="ejbDoclet">
<mkdir dir="${ejbDoclet}"/>
<mkdir dir="${services.build}" />
<ejbdoclet destdir="${ejbDoclet}" excludedtags="@version,@author" addedtags="@xdoclet-generated at ${TODAY}" ejbspec="2.0">
<fileset dir="${ejbApp}">
<include name="com/ads/app/property/entity/DataBean.java" />
</fileset>
<entitypk/>
<remoteinterface pattern="{0}"/>
<homeinterface/>
<localinterface pattern="{0}Local" />
<localhomeinterface />
<deploymentdescriptor destdir="${oms.services.build}/META-INF" mergeDir="${descriptorsOMS}" />
<weblogic version="7.0" datasource="XYZ" xmlencoding="UTF-8" destdir="${services.build}/META-INF" />
</ejbdoclet>
</target>

I am not sure what is missing or what else needs to be done.
Thanks.
