Starting the service

During server installation, you might have chosen to start the service automatically. If you did,

the service will be started whenever the server machine is started, and you don’t need to start it

manually. If you did not, you can start the server from the Windows Start menu: choose Programs

> Macromedia Flash Communication Server MX > Start Service. On Windows, to confirm that

the service is running, open the Task Manager and make sure both FlashCom.exe and

FlashComAdmin.e are listed in the Processes tab.

Opening a connection to the server

Open a new file in the Flash authoring environment, and then add the client-side ActionScript

commands to connect to the server.

To use ActionScript to connect to the server:

1 In a new Flash movie, begin opening a connection to the Flash Communication Server by

issuing the following command:

my_nc = new NetConnection();

Follow this command with a connect command:

my_nc.connect(targetURI);

In this basic syntax for NetConnection.connect (omitting optional parameters), targetURI

is the Uniform Resource Identifier (URI) of an application on the Flash Communication

Server that should run when the connection is made. To specify

targetURI, use one of the

following formats (items in brackets are optional):

rtmp:[port]/appName[/instanceName] (acceptable if the movie and the Flash

Communication Server are on the same computer)

rtmp://host[:port]/appName[/instanceName]

Note that in both syntax examples for targetURI, you must specify rtmp (the Real-Time

Messaging Protocol) as the protocol for the connection. If you omit it, the Flash Player

assumes you want to make an HTTP connection to an application server, and your connection

will fail.

If the server is running on your local machine, you can use

"localhost" as the host name in

the URI; this is often convenient during application development.

For example, the following code uses the

new NetConnection constructor to create a new

connection object. Then, the object is connected to the server with the call to

my_nc.connect.

// Makes a new connection object

my_nc = new NetConnection();

// Connects to the instance named appInstance

// of the application named appName

// located on the Flash Communication Server

// that is running on myServer.myDomain.com

my_nc.connect("rtmp://myServer.myDomain.com/appName/appInstance");
