This article is for Flex developers who want to integrate their applications with WebSphere Portal. It assumes that you are familiar with Flex at a basic programming level and that you are familiar with Java programming. It also assumes that you have administrative access to a working WebSphere Portal server for the relevant portions of the article. It does not, however, assume that you are familiar with programming or administering WebSphere Portal.

The top rectangle represents a Flex project as the presentation layer that is built by MXML and ActionScript, while the bottom rectangle represents a Java project as the business layer that is built by Java and JDBC. The Flex application calls a Java service through a RemoteObject that is one of the remote procedure call (RPC) components provided by Flex. In this sample application, we will import BlazeDS to implement the remote object.

Adobe Flex is a highly productive, free, open source framework for building and maintaining expressive Web applications that deploy consistently on all major browsers, desktops, and operating systems.
