Application Server Connectivity 87

2 Create the event handler for the Run_btn button. Notice the call to runTests. This invokes

the function you’ll define later in the server-side code. The second parameter,

new Result(),

provides the functionality for receiving the results of the call to runTests.

// Run the simple remoting tests.

function runTests() {

// Get the return value from the Flash Communication Server and

// display it in the ResultBox. In this sample, the server

// is returning the string "Ran the service on the server".

function Result() {

this.onResult = function(str) {

_root.ResultBox.text = str;

}

// Call the "runTests" function on the Flash Communication Server,

// and pass in an instance of the Result function to receive

// the return value from the server.

main_nc.call("runTests", new Result());

}

Create a new network connection and connect to the application.

// Create a new connection and connect to the application

// instance on the Flash Communication Server.

main_nc = new NetConnection();

main_nc.connect("rtmp:/doc_remoting/room_01");

Provide a handler function that the Flash Communication Server can call to return the results

of the tests.

// Handle the server’s update of ResultBox with

// the result of each test.

NetConnection.prototype.postResults = function(result) {

_root.ResultBox.text += "\n" + result;

}

To write the server-side ActionScript for this sample:

1 Create a new file using your server-side ActionScript editor, and load the netservices.asc file to

enable Flash Remoting through the Flash Communication Server.

load("netservices.asc");

In the onAppStart function, define the location of the Flash Remoting service, and connect to

it.

application.onAppStart = function() {

trace("***** on app start");

// Set the default gateway URL

NetServices.setDefaultGatewayUrl("http://localhost:8500/flashservices/

gateway");

// Connect to the gateway

this.gatewayConnnection = NetServices.createGatewayConnection();

}
