I have a problem binding to a RMI registry on localhost. The problems appears to be when the driver tries to bind the server to the registry.
The following exception appears:
Server exception: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.lang.ClassNotFoundException: obli_opgave.CustomerContainer

and here is the code for server driver:

// Bind the remote object's stub in the registry
Registry registry = LocateRegistry.getRegistry();
registry.bind("cust_con", stub);
System.err.println("Server ready");
}
catch (Exception e)
{
System.err.println("Server exception: " + e.toString());
e.printStackTrace();

here is the server code:
