Hey folks!
I am working on a small JPA bundle which should make use of dynamic weaving in order to get lazy loading to work. Unfortunately, I couldn't get it to work and I have no idea what I am doing wrong.  Without dynamic weaving everything works fine.
I followed the offical tutorial ( http://wiki.eclipse.org/EclipseLink/Examples/OSGi/Equinox_By te_Code_Weaving), added the required bundles, added support for dynamic weaving in persistence.xml and started equinox with the parameter " -Dosgi.framework.extensions=org.eclipse.persistence.jpa.equi nox.weaving ".
However, when I try to start my weaving test bundle I get the following exception:
[EL Finer]: Thread(Thread[OSGi Console,5,main])--JavaSECMPInitializer - registering transformer for weaving.jpa.
org.osgi.framework.BundleException: Exception in weaving.test.Activator.start() of bundle weaving.test.

My Activator:
Map<String, Object> properties = new HashMap<String, Object>();
properties.put(PersistenceUnitProperties.CLASSLOADER, this.getClass().getClassLoader());
EntityManagerFactory entityManagerFactory = new PersistenceProvider("org.eclipse.persistence.internal.jpa.deployment.osgi.equinox.EquinoxInitializer").createEntityManagerFactory("weaving.jpa", properties);
EntityManager em = entityManagerFactory.createEntityManager();
I couldn't find any bundle which exports the EquinoxWeaver class. Has anyone an idea what is going wrong with my bundle?
Many thanks in advance and best regards!
Andy
