Hi, so far, I just worked with one binary folder and did not create jars from the project, too. I checked the whole workspace and the eclipse classpath but did not find any double classes or imports. I even removed all classes from the binary folder and rebuilt them.
I debugged my application and had a look at the entity classes. They contain an pcDetachedState and a pcStateManager field. Is this a sign that the classes have been enhanced or do these fields also occur in unenhanced classes? -Naomi -------- Original-Nachricht -------- > Datum: Mon, 18 May 2009 09:17:33 -0700 > Von: Craig L Russell <craig.russ...@sun.com> > An: users@openjpa.apache.org > Betreff: Re: Runtime Enhancement: Problems with Ant Task in Eclipse > Hi Naomi, > > On May 18, 2009, at 8:34 AM, naomi-...@gmx.de wrote: > > > Hey David, > > > > thank you for the tip! > > > > I checked one of my entities with javap: > > > > 1.
