PCEnhancer does not enhance classes specified in the mapping files declared in
the persistence xml
--------------------------------------------------------------------------------------------------
Key: OPENJPA-328
URL: https://issues.apache.org/jira/browse/OPENJPA-328
Project: OpenJPA
Issue Type: Bug
Components: build / infrastructure
Affects Versions: 1.0.0
Reporter: Henry Lai
Attachments: ptpissue5.zip
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.
