In this video I am going to show you the basics of starting your first Red5 java application and we will use Flex to talk to the server and the server will keep track of a list of users that are logged in to the application. As soon as a user closes there browser or leaves the applications page the user will be removed from the applications list of users. This is really helpful for building applications where users are interacting with other users. This could be a Chat or Video application or even an online game where users can play against each other.
Before you can start you will need a couple of things installed. Eclipse with Flex Builder plugin, The Java EE development environment, and finally the Red5 Server Plugin for Eclipse. In the video I will explain a little bit about why you need this setup and where to go to get it but I will not cover installation at all.
I hope you guys enjoy and let me know if you have any questions.
