The Networking Architecture of BlazeDS BlazeDS provides a clean separation of the Selection from Agile Enterprise Application Development with Flex [Book]. In this example I am going to use Spring+BlazeDS integration API for integrating backend Spring based J2EE layer into client layer Flex. So the User Interface is produced using Flex and to take care of the remoting we can use BlazeDS which is Open Source from Adobe. BlazeDS.

One way to do it to use Flex. This is exactly what the Spring BlazeDS project implements. In the flex folder, create blzzeds XML files named services-config. A default configuration file, called services-config.
To enable that I followed the instructions outlined by http: It enables remote procedure calls and message exchanges between the two platforms thereby helping couple together rich and engaging Flash platform based interfaces and robust enterprise servers.

Now I have created blazeds-servlet. This file is the WebLogic application deployment descriptor and contains the shared libraries references. Specifying the domain directory. The channel issues polls to the server to fetch data but if no data is available it waits until data arrives for the client or the configured server wait interval elapses.
