Hi Hez,
It looks like the entities haven't been enhanced. The ant script does this
by specifying a javaagent when it runs hellojpa.Main. I'm not familiar with
the maven exec plugin but it looks like adding the -javaagent argument is
what you need :
<argument>-javaagent:${path.to.openjpa.jar}</argument>
FWIW the ant script obtains the path to openjpa.jar like this :
<path id="javaagent">
<fileset dir="${root}">
<include name="openjpa-*.jar"/>
</fileset>
</path>
<pathconvert property="javaagent" refid="javaagent"/>
hth,
