Web Services, Part IV: WebService Behavior's Objects, Properties, and Events

The WebService behavior, when assembling SOAP messages, uses a default value for almost every property that you don't care about. If you want to impact the way you call a remote Web service, you need to understand the behavior's objects, properties, and events. We'll show you how to set these properties in order to change the default set. For example, we'll explain how to make a synchronous call instead of an asynchronous call. When the message does not return successfully from the Web service, you need to provide a reasonable message to the user. There are several return codes and messages that you can parse and interpret to determine what happened. We'll show you how to utilize the behavior's objects and properties to figure this maze. We'll also show you how to use the two event handlers, onresult and onserviceavailable, to extract more information about the success or failure situation.

In this column you will learn:

• What are the call object's properties (1)
• What are the call object's properties (2)
• What are the result object properties
• How to use the result object
• How to use the onserviceavailable event handler
• How to use the onresult event handler
