Creates and instantiate a new remote object. This method performs the following tasks:

• Finds and loads (if not already loaded) the class of the object being instantiated
• Creates an instance of the object using its special two parameter activation constructor, the first parameter being the ActivationID and the second the MarshalledObject.

Parameters:

id - the id of the object being instantiated

desc - the activation descriptor being instantiated

Returns:

the MarshalledObject, containing the stub to the newly created object.

Throws:

ActivationException - if the activation fails

java.rmi.RemoteException - if the remote call fails
