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.

		channelSet : ChannelSet Provides access to the ChannelSet used by the service.	AbstractService
		concurrency : String Value that indicates how to handle multiple calls to the same service.	WebService
		convertParametersHandler : Function An optional function, primarily intended for framework developers who need to install a function to get called with the parameters passed to each webservice operation invocation.	AbstractWebService
		convertResultHandler : Function An optional function, primarily intended for framework developers who need to install a hook to process the results of an operation before notifying the result handlers.	AbstractWebService
		description : String The description of the service for the currently active port.	AbstractWebService
		destination : String [override] The destination of the service.	AbstractWebService
		endpointURI : String The location of the WebService.	AbstractWebService
		headers : Array [read-only] Returns the array of SOAPHeaders registered for the WebService.	AbstractWebService
		httpHeaders : Object Custom HTTP headers to be sent to the SOAP endpoint.	AbstractWebService
		makeObjectsBindable : Boolean When this value is true, anonymous objects returned are forced to bindable objects.	AbstractWebService
		managers : Array The managers property stores a list of data managers which modify the behavior of this service.	AbstractService
		operations : Object The Operations array is usually only set by the MXML compiler if you create a service using an MXML tag.	AbstractService
		port : String Specifies the port within the WSDL document that this WebService should use.	AbstractWebService
		protocol : String Deprecated: Please Use channelSet [write-only] Deprecated, use the appropriate destination instead, or if using a url, use DefaultHTTP or DefaultHTTPS.	WebService
		ready : Boolean [read-only] Specifies whether the WebService is ready to make requests.	AbstractWebService
		requestTimeout : int Provides access to the request timeout in seconds for sent messages.	AbstractService
		rootURL : String The URL that the WebService should use when computing relative URLs.	AbstractWebService
		service : String Specifies the service within the WSDL document that this WebService should use.	AbstractWebService
		serviceName : String Deprecated: Please Use destination	WebService
		showBusyCursor : Boolean If true, a busy cursor is displayed while a service is executing.	WebService
		useProxy : Boolean Specifies whether to use the Flex proxy service.	AbstractWebService
		wsdl : String The location of the WSDL document for this WebService.	WebService
