AMF3 facilitates a very efficient way of binary transmission of data between the server and the client. There is plenty more, including use of annotations, possible for configuring Spring Beans as remoting destinations and you may want to learn more online from the Spring BlazeDS project site mentioned earlier in this paragraph.

This means you must have a way that all requests coming from the Flex client and intended to be handled by the BlazeDS instance are routed by the DispatcherServlet to the MessageBroker. Pushing data from the server to the client on the server’s initiative and not as a response to a request. Please take a moment to review and update.

To make the application more robust and better partitioned, modify the code as follows:. Building a messaging application. Look at the next two figures for some insight into the context. Make sure that you have the JDK 1. All built-in adapter classes inherit from the ServiceAdapter abstract class.

A second transient connection, drawn from the browser pool, is needed only when data is sent to the server. On endpoints that support translation and serialization between AS3 and Java or even web servicesa serialization filter is defined to intercept calls to the endpoint. Install the Flex Builder 3 plug-in. The settings should look similar to these you may need to adjust the exact folder name based on your own settings: During serialization, the serializer eagerly fetches all the JPA and Hibernate persistent objects and sends them across the wire.

A Remoting destination exposes a Java class that your Flex application can invoke remotely.

Off the shelf, the Flex framework includes three methods of pull-based communication and data interchange with external data sources:.

Long polling can provide near real-time data push by waiting till the response from the server is ready to be dispatched. Prior to the existence of guids project developers relied on custom factories to integrate Spring and BlazeDS. Subscribe to our newsletter?

BlazeDS includes a Java implementation of AMF which is used for remotely communicating with server-side Java objects as well as for passing messages between clients.

I suspect it is much faster than XML Integrating Adobe Blazsds and Java Learn about Adobe’s tool for coupling together Flash platform-based interfaces with robust Java enterprise servers.

Prior to working at Adobe, James built a rich marketing and customer service portal for Pillar Data Systems. Publishing the specification allows other projects to implement AMF based on the specification rather than reverse engineering the protocol. The ActionScriptAdapter helps route messages between Flex clients via the server.

This section describes how to build a simple inventory management application that demonstrates the BlazeDS Remoting Service.
