Sample text

On selection, I move forward to the screen shown in Figure 1-26. On this screen, titled Specify WSDL to Introspect, I specify the address of the WSDL and then let Flash Builder introspect the endpoint definitions. Figure 1-26 You will see all endpoint options come up on the next screen. 1. For this example, I pick up a free public web service that allows looking up weather information by zip code and place name. Figure 1-27 shows a snapshot of the SOAP endpoint definitions for this service, which are presented after introspection.

MXML is an XML-based declarative language, which makes programming intuitive and easy. All MXML code is translated automatically to AS3 before it’s compiled. This intermediate AS3 representation of the MXML code is often deleted unless a developer Chapter 1: Flex for Java Developers specifies that that it be saved. Generated AS3 representations of MXML can be saved by explicitly specifying the ‘‘-keep’’ option to the Flex compiler. AS3 compiles to a byte code format called ‘‘swf,’’ that runs within the Flash Player virtual machine.

The load event is dispatched on the WebService component when a WSDL is loaded. This is when you are ready to initialize and make the remote web service procedure calls. Each remote call either 30 Chapter 1: Flex for Java Developers succeeds or fails. As with the HTTPService, a result or a fault event is activated, depending on whether the response was a success or failure. A single web service endpoint can define multiple methods or operations. It’s possible to define different or the same result and fault handlers for these operations.
