The <mx:WebService> tag gives you access to the operations of SOAP-compliant web services.

MXML Syntax expanded

Hide MXML Syntax

The <mx:WebService> tag accepts the following tag attributes:

 <mx:WebService
   Properties
   concurrency="multiple|single|last"
   destination="No default."
   id="No default."
   serviceName="No default."
   showBusyCursor="false|true"
   makeObjectsBindable="false|true"
   useProxy="false|true"
   wsdl="No default."
 
   Events
   fault="No default."
   result="No default."
 />

An <mx:WebService> tag can have multiple <mx:operation> tags, which have the following tag attributes:

 <mx:operation
   Properties
   concurrency="multiple|single|last"
   name=No default, required.
   resultFormat="object|xml|e4x"
   makeObjectsBindable="false|true"
 
   
   Events
   fault=No default.
   result=No default.
 />

An <mx:Operation> tag contains an <mx:request> tag. To specify an XML structure in an <mx:request> tag, you must set the value of the tag's format attribute to "xml". Otherwise, the body is converted into Objects.

Property Detail

concurrency

property

concurrency:String

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Value that indicates how to handle multiple calls to the same service. The default value is multiple. The following values are permitted:

multiple - Existing requests are not cancelled, and the developer is responsible for ensuring the consistency of returned data by carefully managing the event stream. This is the default.
single - Making only one request at a time is allowed on the method; additional requests made while a request is outstanding are immediately faulted on the client and are not sent to the server.
last - Making a request causes the client to ignore a result or fault for any current outstanding request. Only the result or fault for the most recent request will be dispatched on the client. This may simplify event handling in the client application, but care should be taken to only use this mode when results or faults for requests may be safely ignored.

Implementation
public function get concurrency():String
public function set concurrency(value:String):void

protocol

property

protocol:String [write-only]

Deprecated: Please Use channelSet

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Deprecated, use the appropriate destination instead, or if using a url, use DefaultHTTP or DefaultHTTPS. The deprecated behavior will simply update the destination if the default is being used.

Implementation
public function set protocol(value:String):void

serviceName

property

serviceName:String

Deprecated: Please Use destination

Implementation
public function get serviceName():String
public function set serviceName(value:String):void

showBusyCursor

property

showBusyCursor:Boolean

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

If true, a busy cursor is displayed while a service is executing. The default value is false.

Implementation
public function get showBusyCursor():Boolean
public function set showBusyCursor(value:Boolean):void

Constructor Detail

WebService

()

Constructor

public function WebService(destination:String = null)

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Creates a new WebService component.

Parameters

destination:String (default = null) — The destination of the WebService, which should match a destination name in the services-config.xml file. If unspecified, the WebService component uses the DefaultHTTP destination.

Method Detail

getOperation

()

method

override public function getOperation(name:String):AbstractOperation

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Returns an Operation of the given name. If the Operation wasn't created beforehand, a new mx.rpc.soap.mxml.Operation is created during this call. Operations are usually accessible by simply naming them after the service variable (myService.someOperation), but if your Operation name happens to match a defined method on the service (like setCredentials), you can use this method to get the Operation instead.

Parameters

name:String — Name of the Operation.

Returns

AbstractOperation — Operation that executes for this name.

initialized

()

method

public function initialized(document:Object, id:String):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Called automatically by the MXML compiler if the WebService is setup using a tag. If you create the WebService through ActionScript you may want to call this method yourself as it is useful for validating any arguments.

Parameters

	`document:Object` — the MXML document on which this WebService lives

	`id:String` — the id of this WebService within the document
