Messaging and Streaming > RTMP Messaging

A messaging application is a logical unit combining the following elements:

1.	Custom application code - this is the code working with client connections, processing server-side and client-side events and enforcing business logic.

2.	Video streams - WebORB automatically supports live or recorded stream broadcast, it can provide server-initiated streaming and record streams published by clients. Streams created and managed within application scope.

3.	Remote Shared objects - WebORB supports Remote Shared Object (RSO) API enabling clients exchange data with each other or with the server. RSOs created and managed within the application scope.

Real-time messaging applications must be identified by a directory under the /Applications folder located in the root of a WebORB-enabled ASP.NET application. For example, the following structure creates two applications MyVideoApp and SharedObjectsApp:

WebORB version 3:

Inetpub
+-wwwroot
+-weborb30
+-Applications
+-MyVideoApp
+-SharedObjectsApp

WebORB version 4:

Program Files
+-Weborb for .NET
+-[WEBORB VERSION FOLDER]
+-Applications
+-MyVideoApp
+-SharedObjectsApp

To connect to a messaging application from a Flash/Flex client, use the application name in the NetConnection.connect method call as shown below:

private var nc:NetConnection;

public function establishConnection():void
{
nc = new NetConnection();
nc.objectEncoding = ObjectEncoding.AMF0;
var uri:String = "rtmp://localhost:2037/SharedObjectsApp";
nc.connect( uri );
}

Flex clients can dynamically determine the base URL (hostname and port) using the following API:

var uri:String = ServerConfig.getChannel( "weborb-rtmp" ).endpoint;
