Hey folks,
I'm trying to give my application a big performance boost by making the lazy-loading work. Therefore I am trying to make use of dynamic weaving. As I couldn't get it to work within my Eclipse RCP application, I set up a minimalistic Equinox test environment (very similar to [1]) which can be run outside of the Eclipse IDE - it can be downloaded from [4], the complete test case including all third-party libs can be downloaded from [5].
I followed the bundle-start-level rules described in [1], weaving is enabled in persistence.xml, the weaving-hook-fragment is registered properly to the org.eclipse.osgi master bundle... I can't see what's going wrong with my test case.
Here is the code of my bundle's Activator:
public class Activator implements BundleActivator {
public void start(final BundleContext context) throws Exception {
if (createEntityManagerFactory()) {
if (Helper.classImplementsInterface(Foo.class, PersistenceWeaved.class)) {
System.out.println("Foo is woven");
} else {
System.err.println("Foo is not woven");
}
if (Helper.classImplementsInterface(Bar.class, PersistenceWeaved.class)) {
System.out.println("Bar is woven");
} else {
System.err.println("Bar is not woven");
}
}
}
public boolean createEntityManagerFactory() {
final Properties properties = new Properties();
properties.put(PersistenceUnitProperties.CLASSLOADER, this.getClass().getClassLoader());
final EntityManagerFactory emf = new PersistenceProvider().createEntityManagerFactory("default", properties);
if (null == emf) {
return false;
}
final EntityManager em = emf.createEntityManager();
if (null == em) {
emf.close();
return false;
}
em.close();
return true;
}
public void stop(final BundleContext context) throws Exception {
}
}
As you can imagine, the resulting output looks like this:
Foo is not woven
Bar is not woven
The short status of my bundles looks like this:
osgi> ss

</properties>
</persistence-unit>
</persistence>
Here are the versions I am currently using for this test:
- Equinox/Eclipse: 3.6M2
- Derby ([2]): 10.1.2
- EclipseLink ([3]): 1.2.0 OSGI bundles
Help is very appreciated!!! 
Thanks in advance,
