          Components: CMP service
    Affects Versions: JBossAS-4.0.5.GA
         Environment: Windows XP, JBoss 4.0.5GA, JBoss 4.0.4GA and JBoss 3.2.8.SP1

Hi all,

I'm having a similar problem with one to many relationship, CMP persistence and EJB 2
specification. I have tested the problem at versions 3.2.8.SP1, 4.0.4.GA and 4.0.5.GA, and
they all throws the same Exception. I have an ExperimentEJB that is related to many
ConfigurationEJB. When I try to add the ConfigurationEJB Collection to ExperimentEJB, the
system throws this exception:

11:07:01,323 ERROR [LogInterceptor] RuntimeException in method: public abstract void

periment.setConfiguration(java.util.Collection) throws java.rmi.RemoteException:

The code that add the data to the relationship is like this:

* This is part of the function that generates the collection for the relationship:

public static Vector generateConfiguration(long experimentId, ConfigurationHome
configurationHome,CouplingInfo coupling) throws RemoteException, CreateException{
			...
			while(it2.hasNext())
			{
				ParameterInfo parameter=(ParameterInfo)it2.next();
				ConfigurationInfo configurationInfo=parameter.getConfigurationInfo();
				Configuration config=configurationHome.create(new
Long(experimentId),coupling.getName(),module.getName(),parameter.getName());
				...
				configurations.add(config);
			}
			return configurations;
}

* This is part of the code that add the collection generated by the previous function:

  			Experiment exp=(Experiment)session.getAttribute("currentExperiment");
  			ConfigurationHome configurationHome=this.softIAMInit.getConfigurationHome();
                        // This is the setter for the relationship

			exp.setConfiguration((Collection)(ConfigurationControl.generateConfiguration(experimentId,configurationHome,coupling)));
