problem with dynamic weaving and class hierarchy [message #658531] Tue, 08 March 2011 20:52 Go to next message

Hello everybody,

first my setup:
- Equinox Runtime
- EclipseLink 2.1.2

I have a datamodel, which includes a class hierarchy like (getter and setters left out):

public abstract class Identifiable {

	private long jpaId = 0;

	private int jpaVersion = 0;
}



public abstract class ObjectWithUrn extends Identifiable {

	private String urn = null;
}


and several subclasses of it (but also some classes only subclassing Identifiable). They are mapped with a orm.xml like:

<?xml version="1.0" encoding="ASCII"?>
<orm:entity-mappings xmlns:orm="http://www.eclipse.org/eclipselink/xsds/persistence/orm" version="2.1">
  <orm:access>METHOD</orm:access>
  <orm:mapped-superclass class="Identifiable">
    <orm:attributes>
      <orm:id name="jpaId">
        <orm:generated-value strategy="SEQUENCE"/>
      </orm:id>
      <orm:version name="jpaVersion"/>
    </orm:attributes>
  </orm:mapped-superclass>
  <orm:mapped-superclass class="ObjectWithUrn" name="ObjectWithUrn">
    <orm:attributes>
      <orm:basic name="urn" optional="true"/>
    </orm:attributes>
  </orm:mapped-superclass>
<!-- .... -->
</orm:entity-mappings>


Bundle start order is like:
1 javax.persistence
2 org.eclipse.persistence.jpa
3 my.bundle

Dynamic Weaving is enabled in the persistence.xml. When creating an EntityManager I get an exception:

If I use static weaving it works without problems. I get no log messages that the both classes are registered to be processed by weaver.

I would really appreciate any help, if you need more information, I'll provide it.
Thanks in advance!

Hello,

There is a note on using Equinox OSGI with weaving here:
http://wiki.eclipse.org/EclipseLink/Examples/OSGi/Equinox_By te_Code_Weaving

It looks like a classloading issue, are you passing in the classloader to the createEntityManagerFactory call?

Best Regards,
Chris
