Hi Jeremy,
your suggestion is exactly what I do, but unfortunately since I have to specify
this in Eclipse in the 'installed JRE' default VM args, I can only change it
manually, so in one batch run, I can't stop OpenJPA modifying the entity beans
during a Hibernate or Toplink test.
Regards

Adam,
Provided you have your pu's defined separately, the agent allows you to
specify a particular persistence unit for enhancement. Example:
-javaagent:C:/eclipse.workspaces/3.2.2/openjpa-1.2.0/openjpa-all/target/openjpa-1.2.0.jar=pu=OpenJPAPU

Hi Kevin,
whilst on the subject, I'm using this in Eclipse too but there is one thing
that it appears cannot be done.
One of the projects I work on is a framework that is designed to be used
with any JPA provider, and the testing runs against OpenJPA as well as
Hibernate and Toplink Essentials.
Obviously I don't want the javaagent to act on my entity classes when I'm
running Hibernate or Toplink, but there appears to be no easy way to stop it
from one test to another in a batch run.
It would be interesting to know whether there are plans to abandon the byte
code rewriting, and what the history behind its adoption is. I would assume
that it's performance but I haven't had seen any comparative stats between
the different JPA providers.

Hi Gianny,
I use this all the time. On my Run configuration for the application that
I
am running I will put something like the following as a JVM argument...
-javaagent:C:/eclipse.workspaces/3.2.2/openjpa-1.2.0/openjpa-all/target/openjpa-1.2.0.jar
This should kick in the PCEnhancerAgent for the Entity classes that are
being loaded.

Hi,
I am unable to get javaagent based enhancement work within Eclipse.
Based on a cursory review of PCEnhancerAgent, I can see that no
ClassFileTransformer is installed when
List<String> anchors = Configurations.
getFullyQualifiedAnchorsInPropertiesLocation(opts);
returns an empty list, which it does in my case when I simply specify the
following JVM arg
-javaagent:<path to>/openjpa-1.2.0.jar
