                 Key: OPENJPA-468
                 URL: https://issues.apache.org/jira/browse/OPENJPA-468
             Project: OpenJPA
          Issue Type: Bug
         Environment: Windows
            Reporter: Sebastian Souza
             Fix For: 1.1.0


 I had well defined my classes in the orm.xml but the enhancer at build time cant find them in the metadata

this is part of the trace :

    [openjpac] java.io.FileNotFoundException: file:C:\Users\Seba\workspace\Persistence\persistence_entities.jar!\itsm\framework\persistence\entities\PersistentObject.class (The filename, directory name, or volume label syntax is incorrect)

this is my build.xml
