	Here we obtain a reference to the factory's portType. Notice how we only need the factory's URI to do this.
	Once we have the factory's portType, we use it to invoke the createResource operation. This operation returns an endpoint reference, 'boxed' inside a CreateResourceResponse object. This endpoint reference includes both the instance service's URI and the new resource's identifier. In the next client we will take a peek inside the endpoint reference.
	Using the instance EPR, we obtain a reference to the MathPortType in the instance service.
	We now use the MathPortType to invoke add, subtract, and getValueRP.
