CHAPTER 5

Application Server Connectivity

This chapter explains how to use Macromedia Flash Remoting services to add application server

connectivity to your Macromedia Flash Communication Server MX application. Macromedia

Flash Remoting is a gateway that connects your communication application to J2EE application

servers and Microsoft Windows .NET servers. Flash Remoting relies on its own client-side

ActionScript library, called NetServices, to link Macromedia Flash MX movies to a server-side

gateway.

The samples in this chapter illustrate how you can make Flash Remoting calls in your server-side

ActionScript to access NetServices. In the context, the Flash Communication Server acts as a

client to Flash Remoting. These samples work with Macromedia ColdFusion MX, which

includes Flash Remoting. To use Flash Remoting with other application servers, see the Flash

Remoting site (http://www.macromedia.com/go/flashremoting).

Connecting through Flash Remoting

“Common client-server workflows” on page 23 describes the different ways you can use Flash

Communication Server to connect clients and servers. The subsection “Connecting to external

sources” shows the Flash Communication Server connecting to other services. The client invokes

a method on the Flash Communication Server, which in turn invokes a method on additional

servers. The results move from the application server to the Flash Communication Server, and

finally back to the client.

Using the Flash Communication Server together with the Flash Remoting NetServices library,

you’ll invoke a Flash Communication Server method from the client, passing some parameters.

The Flash Communication Server will then invoke a NetServices method. When the NetServices

method passes the result to the Flash Communication Server, the server returns it to the client.

Re-creating the samples

The samples assume you’re using the Flash MX authoring environment on the same local host

that is running the Flash Communication Server and ColdFusion MX. Files associated with the

samples (FLA, SWF, HTML, and ASC) are located in subdirectories of the \Macromedia\Flash

MX\flashcom_help\help_collateral directory.

As with the samples in earlier chapters, you’ll create the user interface in a FLA file using the

client-side ActionScript. The client-side ActionScript in the FLA file will invoke a method in the

server-side ASC file that you will also create.

To add Flash Remoting services to your application, you’ll use server-side ActionScript in an ASC

file that you will create. This server-side code will act as a client to the Flash Remoting service by

invoking methods in the ColdFusion CFC file, which you will also create.
