248 Use ColdFusion Event Gateway Adapter

Send a message to ColdFusion

In this section, you create a function to send a message through the Flex Messaging event

gateway to a ColdFusion application. You then create a structure, named msg, that contains

the gateway ID, and the information necessary to send an e-mail message. The gateway ID is

the ID you assign when you create the gateway instance in ColdFusion MX Administrator.

Finally, you send the message to ColdFusion.

1. Directly below the initApp method, add the following code:

public function sendMessage():void {

var msg:AsyncMessage = new AsyncMessage();

msg.headers.gatewayid = "Flex2CF2";

msg.body = new Object();

msg.body.emailto = emailto.text;

msg.body.emailfrom = emailfrom.text;

msg.body.emailsubject = emailsubject.text;

msg.body.emailmessage = emailmessage.text;

pro.send(msg);

messagestatus.text = "Message sent to ColdFusion.";

}

Save the file.

Receive a message from ColdFusion

In this section, you display a message sent from ColdFusion.

1. Add the following function after the sendMessage function:

private function messageHandler(event:MessageEvent):void {

messagestatus.text = "Message received from ColdFusion";

}

Save the file as flexemail2cf.mxml. in the

C:\fds2\jrun4\servers\default\samples\dataservice\maypp folder.

Verify that your code is correct

Your code should match the following code example. Verify that the content is correct.

<?xml version="1.0"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"

layout="absolute"

creationComplete="initApp()">
