* this test handleMessage method is obviously not what a customer might write, but it does
* the trick for kicking the tires in the handler framework. The AddNumbers service takes two
* ints as incoming params, adds them, and returns the sum. This method subtracts 1 from the
* first int on the inbound request, and subtracts "deduction" from the int on the outbound
* response. So the client app should expect a sum 3 less than a sum with this handler
* manipulating the SOAP message.
