Subject [jira] Created: (OPENJPA-96) Runtime Enhancement only processes first persistence unit defined in persistence.xml
Date Tue, 09 Jan 2007 16:41:27 GMT
Runtime Enhancement only processes first persistence unit defined in persistence.xml
------------------------------------------------------------------------------------

                 Key: OPENJPA-96
                 URL: https://issues.apache.org/jira/browse/OPENJPA-96
             Project: OpenJPA
          Issue Type: Bug
          Components: jpa
            Reporter: Kevin Sutter


(This Issue may be related to OPENJPA-9, but since that one was specific to static PCEnhancing,
I thought I would open a separate Issue.  Just in case the solutions are separate.)

I'm using dynamic runtime enhancement via the -javaagent parameter.  It seems that only the
first persistence-unit defined in the persistence.xml is being processed for the runtime enhancement.
 If the persistence.xml has only one entry, no problem.  But, if it has more than one entry,
then only the first persistence-unit definition is being processed for the dynamic enhancement.

When I turn trace on, I get the following message when the runtime enhancement works:

8312  my persistence unit  INFO   [main] openjpa.MetaData - Found 1 classes with metadata
in 0 milliseconds.
8943  my persistence unit  TRACE  [main] openjpa.Enhance - "com/ibm/ws/persistence/tests/simple/TestEntity"
requires runtime enhancement: true
9043  my persistence unit  TRACE  [main] openjpa.MetaData - Loading metadata for "class com.ibm.ws.persistence.tests.simple.TestEntity"
under mode "[META][QUERY]".

When this p-u definition is not first in my persistence.xml, the "8943" message is missing
and my test fails:

8512  my persistence unit  INFO   [main] openjpa.MetaData - Found 1 classes with metadata
in 0 milliseconds.
8522  my persistence unit  TRACE  [main] openjpa.MetaData - Using metadata factory "org.apache.openjpa.persistence.jdbc.PersistenceMappingFactory@37e837e8".
8522  my persistence unit  TRACE  [main] openjpa.MetaData - Loading metadata for "class com.ibm.ws.persistence.tests.simple.TestEntity"
under mode "[META][QUERY]".

I eventually get the following message when running the testcase:

<4|false|0.0.0> org.apache.openjpa.persistence.ArgumentException: Attempt to cast instance
"com.ibm.ws.persistence.tests.simple.TestEntity@60606060" to PersistenceCapable failed.  Ensure
that it has been enhanced.
