Hello world,

I have a problem in using the RMI method "rebind" in the start method
of my bundle. I have this source code :

// ---------------------------------------------------------
IMyObject myObject = new MyObject();
SecurityManager securityManager = null;
securityManager = new RMISecurityManager();
System.setSecurityManager(securityManager);
LocateRegistry.createRegistry(9090);
Naming.rebind("rmi://localhost:9090/testMyObject", myObject);
// ----------------------------------------------------------

This code works well in a normal Java Project and I have configured the
java.policy file with :

grant {
permission java.security.AllPermission;
};

But in the equinox environment an Exception is thrown :

// -----------------------------------------------------------
java.security.PrivilegedActionException: java.rmi.ServerException:
RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested
exception is:
java.lang.ClassNotFoundException:
fr.itcs.exec.service.distinfra.rmi.IMyObject
// -----------------------------------------------------------

If anyone has encountered this problem, I will be pleased to hear his
solution. (May be a ClassLoader problem ?)

Mickael.

Hi Mickael,

I suffer the same problem than you.
If you have the chance, replace:

LocateRegistry.createRegistry(9090);
Naming.rebind("rmi://localhost:9090/testMyObject", myObject);

by:

Registry registry = LocateRegistry.createRegistry(9090);
registry.rebind("testMyObject", myObject);

You shouldn't have any problem with this code.

BR,
Jaime

Thank you,

It works. The problem is that the RMI Naming class is loaded by the
System Class Loader and not by my bundle class loader. For the Registry
class it is different because it is my bundle who creates it.

Thanks.

Mickael.

Hi,

I have a simillar Problem, but still didn't manage to get the RMI
running. How do you solve this class loader issue? Maybe you have a idea?

The server code:
public class RMITest{

public RMITest() throws RemoteException, MalformedURLException {
System.setSecurityManager(new RMISecurityManager());
LocateRegistry.createRegistry(Registry.REGISTRY_PORT);
RemoteServer.setLog(System.out);

FacadeTest stub = (FacadeTest) UnicastRemoteObject.exportObject(new
FacadeTestImpl(), 0);

Registry registry = LocateRegistry.getRegistry();
registry.rebind("FacadeTest", stub);
}
}

The Exception:
java.rmi.UnmarshalException: error unmarshalling arguments; nested
exception is:
java.lang.ClassNotFoundException: org.unicase.emfstore.rmi.FacadeTest
at sun.rmi.registry.RegistryImpl_Skel.dispatch(Unknown Source)
