Is it possible to track web services call ?

Question

Hi,
I have a Tomcat application server exposing web services; I have a client that accesses those web services using apache axis. More deeply, from client I do something like:
           Service  service = new Service();
           Call call = (Call) service.createCall();
           call.setTargetEndpointAddress(url);
           call.setOperationName(methodName);
           call.setUsername(userName);
           call.setPassword(password);
           Object o = call.invoke(args);I would like to log, for each call, some sort of "unique identifier of the call", both client side and server side.
How can I do this ?
Any help would be very appreciated!

I think one of the ways to implement such thing, is to add some identifier parameter to header of soap message. For example when client calls service you change that identifier on your server and store it somewhere for example in some static field. And you add this parameter to your response SOAP message header so client side can get it.
