Here is the Add Web service in action:

Enter First Number:
Enter Second Number:
 The function addNumbers() is invoked when the Add button is clicked. It calls the webservice behavior's callService() method. The parameters are: (i) the function that handles the result display, (ii) the Web service command, add, (iii) the first number, and (iv) the second number:

function addNumbers(a, b) {
  myWebService.simpleCalcWebService.callService(addResult, 
    "add", first.value, second.value);
}
These Web service examples work properly in Internet Explorer 5.5 or later browsers. If you are using Internet Explorer 5.5+ and receiving errors with the examples, you need to enable the access data sources across domains option. See Column 105 for details.
