This is my workaround for JPA 2.1 on Resin. We've had to put that
upgrade aside for a while now so it hasn't been thoroughly tested and
there may be bumps down the road, but at least this allowed us to boot :-/
/** Remove Caucho's JPA implementation Amber - included in Resin -
from the list of registered persistence providers. */
public static void removeAmberPersistenceProvider() {
final PersistenceProviderResolver persistenceProviderResolver =
PersistenceProviderResolverHolder.getPersistenceProviderResolver();
persistenceProviderResolver.getPersistenceProviders(); // Make sure
the persistence provider cache has been initialized
final Map<ClassLoader, PersistenceProviderResolver> resolvers =
(Map<ClassLoader, PersistenceProviderResolver>)
ReflectionUtils.getPrivateField(persistenceProviderResolver, "resolvers");
PersistenceProviderResolver clPersistenceProviderResolver =
resolvers.get(Thread.currentThread().getContextClassLoader());
final List<WeakReference<Class<? extends PersistenceProvider>>>
resolverClasses = (List<WeakReference<Class<? extends
PersistenceProvider>>>)
ReflectionUtils.getPrivateField(clPersistenceProviderResolver,
"resolverClasses");
Iterator<WeakReference<Class<? extends PersistenceProvider>>> iter
= resolverClasses.iterator();
while(iter.hasNext()) {
WeakReference<Class<? extends PersistenceProvider>> ref =
iter.next();
if(ref.get() != null &&
"com.caucho.amber.manager.AmberPersistenceProvider".equals(ref.get().getName()))
{
iter.remove();
}
}
}

I'm basically having the same problem that is outlined in the previous
resin-interest pose (
https://www.mail-archive.com/[email protected]/msg06062.html) and
on Stack Overflow (
http://stackoverflow.com/questions/26352912/jpa-2-1-not-loaded-in-resin-3-1-9),
but I'm using the latest Resin (4.0.43). I've tried following the
instructions in the sited caucho bug report (
http://bugs.caucho.com/view.php?id=5678), but I still get the same
exception. Any pointers would definitely be appreciated.
