I suspect it is much faster than XML Net, PHP, Ruby or any number of other server-side technologies.
BlazeDS – Wikipedia
You need to be careful about performance of AMF Being open source, BlazeDS is freely available and can be downloaded from http: Add event handlers to improve the application RemoteObject calls are asynchronous. For some time, Flash Player has supported a transport protocol that alleviates the unnecessary bottlenecks associated with text-based protocols and provides developers a simpler method of communicating with servers.
Simply put, at the heart of BlazeDS is a Servlet that bootstraps the infrastructure that intercepts all calls between a Flex client and the BlazeDS instance. Because, the message type is an AsyncMessage, that class must be imported. Data Format Optimization AMF3 facilitates a very efficient way of binary transmission of guid between the server and the client.
Getting Started with BlazeDS
This web application contains a number of preconfigured sample applications that can be accessed at http: One is needed for the streamed response from the server to the client that the channel hangs on to. Similarly, in the next step, the instance of the ActionScript Product class passed as an argument to the update method of the RemoteObject is deserialized into an instance of the Java version of the Product class at the server-side.
The reason for this special need arises because of the way BlazeDS serializes data across the wire.
Hi James, Well, my opinion is not neutral: The first announcement is that the specification for AMF is now publicly available. In addition, this data abstraction layer consumes resources on the server-side and client-side when the data is serialized and deserialized see Figure 1.

But differences in how data is passed over HTTP can dramatically reduce application performance as well as developer productivity. This is exactly what the Spring BlazeDS project implements. You will be sent an email to validate the new email address.
You can download Eclipse at: With the help of this project it becomes easy to configure Spring Beans as server side remoting counterparts developdr Flex clients. During serialization, the serializer eagerly fetches all the JPA and Hibernate persistent objects and sends them across the wire. The messaging service in Flex itself is agnostic to the messaging protocol used on the server side.
String; public var price: Among others, the BlazeDS proxy capabilities have three important use cases including:. Email me replies to any of my messages in this thread.
Building Web and Desktop Applications with BlazeDS and AMF
The settings should look similar to these you may need to adjust the exact folder based on your own settings: For example a service class configured as a Spring Bean as follows: Jimmy, can you elaborate on your comment please? A key element of a destination is the channel used to exchange data between the client and the server. Polling is very resource and network intensive.
Can easily be used as a remoting destination simply by specifying a configuration as follows:. A default configuration file, called services-config. Distributing work optimally between a client and its server is an important challenge when architecting RIA.
