This is the Title of the Book, eMatter Edition

Chapter 1: Introduction to Flash Remoting

SELECT username FROM Users

WHERE username = '#username#' and password = '#password#'

</cfquery>

</cfif>

<cfoutput>#returnXML#</cfoutput>

As you can see, the code is not intuitive—the XML is manually serialized into a

string on both client and server, and the string has to be deserialized and turned into

an XML object again on the Flash side. All of this code was created to send one sim-

ple XML object from the Flash movie to the server and back again. Imagine if this

were something more complex, such as a recordset with 10 or 15 fields and 1,000

rows.

The Flash Remoting version of the previous code might look like this:

var myURL = "http://127.0.0.1/flashservices/gateway";

var myServer = NetServices.createGatewayConnection(myURL);

var myService = myServer.getService("com.oreilly.frdg.authentication", this);

myService.getLogin(username, password);

// The result handler for the getLogin( ) method invocation

function getLogin_Result (result_rs) {

if (result_rs.getLength( ) < 1) {

greeting = "Login failed";

} else {

greeting = "Hello " + result_rs.getItemAt(0).username;

greeting += ". Login was successful";

}

And the server-side code might look like this:

SELECT username FROM Users

WHERE username = '#username#' and password = '#password#'

</cfquery>

</cffunction>

</cfcomponent>
