Sets the properties of an object given the command line args. if args contains: --ack-mode=AUTO --url=tcp://localhost:61616 --persistent then it will try to call the following setters on the target object. target.setAckMode("AUTO"); target.setURL(new URI("tcp://localhost:61616") ); target.setPersistent(true); Notice the the proper conversion for the argument is determined by examining the setter arguement type.
