Here is the problem I've been experiencing while trying to run the OpenTrade
sample application. I've been trying to isolate the problem by creating a
simple gwt application and the trying to persist a simple entity but the
problem is the same.
I'd done a little research and I got this annoying problem related to the
enhance process with the entity classes. It suppose to be contemplated by
the persistence unit properties:
<property name="openjpa.DynamicEnhancementAgent" value="false"/>
<property name="openjpa.RuntimeUnenhancedClasses"
value="unsupported"/>
Nonetheless, this not seem to be working. I just don't want that OpenJPA try
to modify my classes through reflection, but it seems not to be solution to
that. This issue is very annoying and is getting me out of the real problem.
I hope you can help me with this.
Please, do not hesitate in contact me for asking. This is really important
to me.
Looking forward to hearing from you.
Kind regards,
Andres
