Because you will work on both the client side and the server side of the applications built in this tutorial, you need to use Flex Builder plug-in configuration and install Flex Builder 3 on top of Eclipse. Developers can use the messaging system to easily send messages from the client to the server or from the server to client. When the application has initialized, it subscribes to the message system.
Install the Flex Builder 3 plug-in. To work with typed objects in this application, first create the ActionScript version of the Product class created in step 1:
