Hi Roger,
The entities are definitely not getting enhanced. Have you tried specifying
the .class files instead of the .java ones?
ie :
<openjpac>
<!-- classpath where the tool look for classes to
enhance. This is the default location in a NB project
directory layout where classes are built -->
<classpath>
<pathelement location="${basedir}/build/classes"/>
</classpath>
<!-- I put it in here. See below the persistence.xml file -->
<config propertiesFile="${basedir}/src/META-INF/persistence.xml"/>
* <fileset dir="${basedir}/build/classes">
<include name="**/entities/*.class"/>
</fileset>
* </openjpac>
