Chapter 17 ❑ ❑ The port name (port_name) The location of the service (webservice_url) To understand how to find this information, it’s best to look at a real WSDL file. The Temperature Service is a Web service provided by XMethods (http://www.xmethods.net), a public Web service publisher as well as a directory of publicly accessible Web services. This service accepts a five-digit U.S. zip code and then returns the current temperature for that area. The WSDL file for the Temperature Service looks like this: Returns current temperature in a given U.S. zipcode 512
Web Services The pertinent information (highlighted previously) from this file is the following: ❑ ❑ ❑ ❑ ❑ The only operation is called getTemp. The SOAP action for getTemp is “” (an empty string). The target namespace for the input to getTemp is urn:xmethods-Temperature. The name of the port is TemperaturePort. The service location is http://services.xmethods.net:80/soap/servlet/rpcrouter. Depending on the type of consumer used to access Web services, you may need to know some or all the previous information. Web Services in Internet Explorer The folks over at Microsoft were kind enough to create an HTML component (also called a behavior) that hides a lot of the ugly details from developers who wish to consume Web services. An HTML component is essentially a COM component defined using XML and JavaScript. HTML components can have properties, methods, and support custom events, making them ideal for creating functionality that doesn’t exist in the browser by default. The downside is that only Internet Explorer supports HTML components, and thus Microsoft’s WebService component does not work in other browsers. The WebService component is available for free from Microsoft’s Web site (http://msdn.microsoft.com/ library/default.asp?url=/workshop/author/webservice/webservice.asp). Using the WebService component After the webservice.htc file is downloaded, place it in the directory with your JavaScript files. You can then access the functionality by applying it to an HTML element. To do this, use the style attribute and the custom behavior CSS attribute: After doing this, the HTML element takes on all the properties, methods, and events of the WebService component. To use the component as a JavaScript object, just assign an ID to the element: Then use the document.getElementById() method to retrieve a reference: var oService = document.getElementById(“service”); Next, you need to specify a Web service to use by calling useService(). The useService() method accepts two parameters: the WSDL file describing the service and a friendly name for the service. A typical call looks like this: oService.useService(sUrl, “FriendlyName”); 513
