246 Use ColdFusion Event Gateway Adapter

Create the Flex application

The Flex application in this tutorial is a simple form in which you specify the elements of an

e-mail message, including the recipient, the sender, the subject, and the message body.

Create a new MXML file

In this section, you create an MXML file in which the layout of user interface elements is

exactly as you specify them, or absolute.

1. In an MXML editor, create a file that contains the following text:

<?xml version="1.0"?>

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

layout="absolute"

creationComplete="initApp()">

</mx:Application>

Save the file as flexemail2cf.mxml. in the

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

Create the user interface

In this section, you create the controls to enter information to send an e-mail message:

1. Add the following MXML code after the <mx:Application> tag:

<mx:Consumer id="consumer" destination="ColdFusionGateway"

message="messageHandler(event)"/>

<mx:TextInput x="103" y="13" width="291" id="emailto" editable="true"/>

<mx:TextInput x="103" y="43" width="291" id="emailfrom" editable="true"/

<mx:TextInput x="103" y="73" width="291" id="emailsubject"

editable="true"/>

<mx:TextArea x="103" y="102" width="291" height="236" id="emailmessage"

editable="true"/>

<mx:Label x="63" y="15" text="To:" textAlign="right"/>

<mx:Label x="37" y="103" text="Message:" textAlign="right"/>

<mx:Label x="52" y="45" text="From:"/>

<mx:Label x="37" y="75" text="Subject:"/>

<mx:Button x="402" y="13" label="Send" id="emailsend"

click="sendMessage();"/>

<mx:Label id="messagestatus" x="103" y="350" width="291" text="message

not sent yet"/>

Save the file.
