Description

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
250 test TRACE [main] openjpa.MetaData - Finished parsing metadata resource "file:/C:/workspace/jpatest/TestOpenJPA/bin/ptp/test/issue5/orm.xml".
250 test TRACE [main] openjpa.MetaData - Parsing class "ptp.test.issue5.T5Entity".
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 - enhanced as persistence-aware.

modify the following method of the PCEnhancer to get it to work
