Class StubLocator


public class StubLocator
extends Object

Finds a stub class like "_HelloStub" that can be instantiated from IOR reference. The returned object can be casted to the used type like "Hello" without using the helper .narrow method, and the object is not unnsecessarily re - instantiated if the .narrow method is used anyway. If no stub, matching the naming conventions, is available, the returned stub replacement can still be used to get the valid request, add parameter and invoke the method by name.
