Also append a hash tag of the unit name to persistence.xml.
i.e for a persistence unit named 'xyz'
$ java org.apache.openjpa.enhance.PCEnhancer -p persistence.xml#xyz
Ensure the following
a) persistence.xml declares all the classes to be enhanced in
clause
b) the classpath contains all the cl

Hi Bengt,
It is not obvious to me how DetachState related options will impact
in-transaction entities. But I am interested to know the result of your
experiment with the options Mark has suggested.
I will recommend you make sure the following
1. Enhance at build time
2. Set openjpa.Restor
Thanks Mark,
I'll give it a try. However, it seems a bit shaky if this is not officially
supported by OpenJPA. Do you know if this will clearly be supported in the
future?

First off, I'd be interested in hearing about the problems that you
encountered when trying to get PCEnhancer working in eclipse.
Secondly, try something like this : java -classpath
/home/luzer/zpd/zpd-ws/jpa_demo/JpaDemo/bin/resourceMgr/model:/home/luzer/tools/apache-openjpa-2.1.0/openjpa-all-2.1
I have a big entity with lots of data which I don't need to send to my
client. Only the primary key and a string should be delivered. All in all I
have to send 6 entities. Now I have two possibilities:
1) I create a simple DTO with just the two required fields and fill it up
with JPA's constru
Hi,
I'm trying to enhance my entities at build time. After failing to get the
ant script for eclipse working, I decided to run the PCEnhancer manually,
without luck though.
When I run PCEnhacer with the following cmd line:
[luzer@cipoc JpaDemo]$ java -classpath
