DEVELOPING COLDFUSION 9 APPLICATIONS 656 Flex and AIR Integration in ColdFusion serviceObject.execute() 5 If the action succeeds, the server returns the result. If there is an exception, it returns the fault. Handle the ResultEvent and FaultEvent objects in the service-specific result handler and fault handler that you specify in the service tag, or in global handlers that you specify in the . The ResultEvent object contains the URL of the File on which the operations have been performed. Users can save this file by downloading it on their machine or rendering it in the application. The FaultEvent object contains the exception details that occurred on the server while performing the operation. For granular control over proxy classes, you can get hold of the underlying RemotObject by using getRemoteObject() method on the proxy class object. For example, for , you can get it using the following code in ActionScript. var mailobject:RemoteObject = mailId.getRemoteObject(); Using the Mail class The Mail class is the proxy for the ColdFusion Mail service, which provides the functionality of the cfmail tag. You specify the required cfmail and child tag attributes for the action as Mail tag attributes. The default Mail action on this tag is send. The following AIR application uses the Mail Service and file upload functionality. It refers to the CFCredentials.mxml file to reference the credentials of the user for authentication. Following is the CFCredentials.mxml file being used for the example:

serviceObject.execute()

If the action succeeds, the server returns the result. If there is an exception, it returns the fault. Handle the

ResultEvent

and

FaultEvent

objects in the service-specific result handler and fault handler that you specify in

the service tag, or in global handlers that you specify in the <cf:config>. The ResultEvent object contains the URL

of the File on which the operations have been performed. Users can save this file by downloading it on their

machine or rendering it in the application. The FaultEvent object contains the exception details that occurred on

the server while performing the operation.

For granular control over proxy classes, you can get hold of the underlying RemotObject by using getRemoteObject()

method on the proxy class object. For example, for <cf:Mail id=”mailId”>, you can get it using the following code in

ActionScript.

var mailobject:RemoteObject = mailId.getRemoteObject();

Using the Mail class

The Mail class is the proxy for the ColdFusion Mail service, which provides the functionality of the cfmail tag. You

specify the required cfmail and child tag attributes for the action as Mail tag attributes. The default Mail action on this

tag is

send

The following AIR application uses the Mail Service and file upload functionality. It refers to the CFCredentials.mxml

file to reference the credentials of the user for authentication.

Following is the CFCredentials.mxml file being used for the example:

<?xml version="1.0" encoding="utf-8"?>

<mx:Panel xmlns:mx="http://www.adobe.com/2006/mxml" currentState="collapsed" toolTip="Double

Click to Collapse/Expand" creationComplete="retrieveCredential()" headerHeight="5"

layout="vertical" mouseDown="check Collapse(event )" resizeEffect="Resize">
