Project: JBoss Application Server
Issue Type: Bug
Security Level: Public (Everyone can see)
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
AMD Sempron 3000+

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 softiam.services.ejbs.experiment.Ex
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)));
