I forgot one piece of this. If the Enhancer classpath points to the lib with the jar files, this error will occur. I had to unpack all of the jars into a single directory and call that the classpath to get past this problem. -----Original Message----- From: Hornbeck, Neil Sent: Friday, August 11, 2006 7:56 AM To: 'open-jpa-dev@incubator.apache.org' Subject: RE: [jira] Commented: (OPENJPA-8) java.util.MissingResourceException: system is missing product derivations
Bryan, I am not so sure that I have a fix. I was using the ant task, and when I fixed this, other issues popped up. I am hesitant to publish a fix since I still don't know what the root cause was, and the fact that new problems popped up makes me doubt its value, but here it is. The 'fix' was to add the classpath to both the taskdef and the target: <taskdef name="openjpac" classname="org.apache.openjpa.ant.PCEnhancerTask" classpathref="ojpa.cp"/> <target name="enhance"> <openjpac> <fileset dir="."> <include name="./src/mymoney/**/*.java" /> </fileset> <classpath refid="ojpa.cp"/> </openjpac> </target> opja.cp referrences both the openjpa code and my code, it may be cleaner to create one classpath to the Enhancer code for the taskdef, and another classpath for source code that the target uses. I haven't tried this yet.
