I am attempting to get JPA and OSGi working together for the first. I have managed to navigate many pitfalls until this one.
I can successfully connect to the DB and run a bogus query
package activator;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import org.osgi.util.tracker.ServiceTracker;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
public class JPABundleActivator implements BundleActivator {
// private BundleContext bundleContext;
// private ServiceTracker serviceTracker;
void log(String msg) {
System.out.println("===== " + msg);
}
@Override
public void start(final BundleContext bundleContext) throws Exception {
log("Starting bundle");
final ServiceTracker serviceTracker = new ServiceTracker(bundleContext, EntityManagerFactory.class.getName(), null);
serviceTracker.open();
new Thread(new Runnable() {
@Override
public void run() {
try {
serviceTracker.waitForService(0);
EntityManagerFactory entityManagerFactory = (EntityManagerFactory) serviceTracker.getService();
EntityManager entityManager = entityManagerFactory.createEntityManager();
System.out.println(entityManager.createNativeQuery("SELECT 'hello'").getSingleResult());
// entityManager.find(OrdHeader.class,1);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}).start();
// PcsDevice pcsDevice =entityManagerFactory.createEntityManager().find(PcsDevice.class,1);
// System.out.println(pcsDevice.getXref1Txt());
}
@Override
public void stop(BundleContext bundleContext) throws Exception {
log("Stopping bundle");
}
}
Results:
Created Framework: org.knopflerfish.framework, version=7.0.1.
Framework launched

===== Stopping bundle

hello
The minute I add an entity class to the persistence.xml however, I get :
