Web Services in Flash :

To use a web services in flash, we must use WebService connector component. The WebServiceConnector component lets you introspect, access, and bind data between a remote web service and your Flash application. A single instance of a WebServiceConnector component can be used to make multiple calls to the same operation. To call more than one operation, use a different instance of a WebServiceConnector component for each operation.
To use the WebServiceConnector component, you need to load the web service's schema into the WebServiceConnector component. A web service's schema is defined by a Web Service Description Language (WSDL) file. The WSDL file, which is accessible through a URL, specifies a list of operations, parameters, and results that are exposed by the web service. Once the schema is loaded, you can proceed to add data bindings.
This example requires an active Internet connection because it uses a public web service. If you use a web service in your application, the web service must be located in the same domain as the SWF file for your application so the application can work in a web browser.

1. Drag a WebServiceConnector component to the Stage and name it tipsWSC.
2. In the Component inspector, click the Parameters tab, if not already selected.
3. Select the WSDLURL parameter, and type the following URL:

http://www.webservicex.net/ValidateEmail.asmx?WSDL

When you specify a web service for a WebServiceConnector component in this way, it is automatically added to the Web Services panel and is available to any application you create.
4. Select Operation, and select the IsValidEmail method.
5. Open the Components Inspecter panel.
6. Click the Schema tab and view the auto-generated schema for the web service.

The Schema tab displays a schematic representation of the service that you are calling. The parameters and results structure are defined within the schema. The Tips schema states that the service expects one String parameter, Email, when it is called; this is the write-only input, as indicated by the right-pointing arrow. The service returns a string as the result of the call; this is the read-only output, as indicated by the left-pointing arrow.

Once the web service's schema is brought into the Schema tab, the items identified within the schema can now be bound, using the Bindings tab, to a variety of UI controls to let users input values for the parameters and to get back and display the results of the web service.
