As far as I know, web services are not like the objects you have in java/c++. Web services are actually functions/methods that you expose over web. They are not mean to be used the way you are talking. Why don't you send all the values in one call to web services. AFAIK, web services don't maintain the conversation state (they are designed that way), and it is always a good practice to reduce number of remote calls otherwise you'll overload the network bandwidth.
