JBossDeveloper

Clebert, all your investigations are highly appreciated!

I suggest you check the classpath. In particular take a look at the ejb3 installation guide:

Because you patched 4.0.3SP1, the client jars in the jboss-4.0.3SP1/client directory will be invalid. Build your client classpath from:

1. jboss-4.0.3SP1/lib
2. jboss-4.0.3SP1/server/all/lib
3. jboss-4.0.3SP1/server/all/deploy/ejb3.deployer
4. jboss-4.0.3SP1/server/all/deploy/jboss-aop-jdk50.deployer

I am doing that as you can see in the test case attached to http://jira.jboss.com/jira/browse/EJBTHREE-440

phon, the "classpath" you pass to JWS may be the same. But the classloader structure in JWS is inherently different from a standalone application.

Maybe take a look at :

http://www.jboss.com/index.html?module=bb&op=viewtopic&t=76791

Could you please post some of you code which shows the relationship mapping.
Alex

I think the problem is with how exceptions are handled on the remote client side which originate form the server. Maybe somebody better suited could shed some light on this issue. Something since RC4 has changed in the way exceptions are passed.

Alex

I just upgraded to 4.0.4RC1 and EJB3 RC5 and have a very similar problem although with different stack trace. After tracing through some code it seems to fail on the HibernateProxy and is fixed by changing lazy relationships to eager. It seems to occur on certain ManyToOne relationships and only on a particular module of mine that has a more complicated relationship structure.

Little by little I am switching relationships from Lazy to Eager to solve the EnhancerByCGLib probs as I see them and I'm worried pretty soon I'll have to load the entire relationship structure every time.

The actual line the failure occurs on is in org.jboss.serial.persister.ClassReferencePersister and it is as follows:

Class clazz = (Class)obj;

I believe the last post refers to me. Here is the root entity bean that is having the various problems. Every other bean that has a relationship to it seems to inherit its problems.

I was hoping for the implementation of the findDevicePoliciesByDevice method. In particular the remote interface would also be good to take a look at.

Below is the method. The actual query will resolve to:

"FROM DevicePolicy devicePolicy WHERE devicePolicy.device = :device"

 public Collection<DevicePolicy> findDevicePoliciesByDevice(Device device, boolean includeDeleted, EagerOnDemand onDemand) throws LocalizableException {
 String alias = DevicePolicy.ROOT.getAlias();
