Description copied from interface: ActivationInstantiator

The activator calls an instantiator's newInstance method in order to recreate in that group an object with the activation identifier, id, and descriptor, desc. The instantiator is responsible for:

• determining the class for the object using the descriptor's getClassName method,
• loading the class from the code location obtained from the descriptor (using the getLocation method),
• creating an instance of the class by invoking the special "activation" constructor of the object's class that takes two arguments: the object's ActivationID, and the MarshalledObject containing object specific initialization data, and
• returning a MarshalledObject containing the stub for the remote object it created

  Specified by:

  newInstance in interface ActivationInstantiator

  Parameters:

  - the object's activation identifier

  - the object's descriptor

  Returns:

  a marshalled object containing the serialized representation of remote object's stub

  Throws:

  ActivationException - if object activation fails

  RemoteException - if remote call fails
