BlazeDS is a set of data services that significantly simplify the development of data-driven Rich Internet Applications, and dramatically improve the performance of their data access operations. In addition, BlazeDS enables the creation of a new breed of real-time data push and collaborative applications. BlazeDS is deployed as a set of JAR files as part of your Web application running in your Java EE application server or servlet container.

BlazeDS consists of three key services:

  • The Remoting Service allows your Flex application to directly invoke methods of Java objects deployed in your application server.
  • The Message Service provides a publish/subscribe infrastructure that allows your Flex application to publish messages and subscribe to a messaging destination, enabling the development of real-time data push and collaborative applications.
  • The Proxy Service allows your Flex application to make cross-domain service requests in a secure and controlled manner. In other words, it allows your Flex application to access a service available on a different domain than the domain from where the application was downloaded (without having to deploy a crossdomain.xml policy file on the target domain).

In this Getting Started tutorial, you will learn how to:

  • Set up your BlazeDS environment
  • Build a messaging application
  • Build a remoting application.
