mgr The QAManagerBase to use.
Sets the QAManagerBase that is used by this web service client to do web service requests.
Note: If you use an EXPLICIT_ACKNOWLEDGEMENT QAManager, you can acknowledge the result of an asynchronous web service request by calling the acknowledge() method of WSResult. The result of a synchronous web service request is automatically acknowledged, even in the case of an EXPLICIT_ACKNOWLEDGEMENT QAManager. If you use an IMPLICIT_ACKNOWLEDGEMENT QAManager, the result of any web service request is acknowledged automatically.
