> running
> org.apache.openjpa.enhance.PCEnhancer -p ptp/test/issue5/persistence.xml
> did not do the class file enhancement, result in The class does not have
> metadata - enhanced as persistence-aware.
> The message are

> resource "file:/C:/workspace/jpatest/TestOpenJPA/bin/ptp/test/issue5/orm.xml".
> 250 test TRACE [main] openjpa.MetaData - Parsing class

> 250 test TRACE [main] openjpa.Enhance - Enhancing type "class
> ptp.test.issue5.T5Entity".
> 250 test WARN [main] openjpa.Enhance - Type "class
> ptp.test.issue5.T5Entity" has no metadata; enhancing as persistence aware. If
> you intended for "class ptp.test.issue5.T5Entity" to be persistence-capable,
> then this means that OpenJPA could not find any metadata for "class
> ptp.test.issue5.T5Entity". This can happen if the directory containing your
> metadata is not in your CLASSPATH, or if your metadata files are not named
> properly. See the documentation on metadata placement for more information.
> 250 test TRACE [main] openjpa.Tool - The class does not have metadata -
