The destination id is a logical name that your Flex application uses to refer to the remote class, which eliminates the blxzeds to hardcode a reference to the fully qualified Java class name.
Getting Started with BlazeDS
Add a destination called tutorial-chat defined as follows: When resources are pooled, blazedw are shared over multiple clients.
Servlet filters can intercept requests to and responses from a Java Servlet.
Run and test the application. Among others, the BlazeDS proxy capabilities have three important use cases including:. Matching endpoints and channels are paired, and that’s when a Flex client and BlazeDS server talk to each other.

A polling channel can be configured with a polling interval, or it can be set up to wait for data at the server-side if data is not immediately available this approach is generally referred to as long polling. Installing BlazeDS is as simple or as complex as deploying a web application in a Java servlet container.
With the help of this project it becomes easy to guife Spring Beans as server side remoting counterparts of Flex clients. This Refcard provides a quick overview of BlazeDS.
On endpoints that support translation and serialization between AS3 blaezds Java or even web servicesa serialization filter is defined to intercept calls to the endpoint. Product” ] annotation to map the ActionScript version of the Product class Product. Its inclusion into future versions of BlazeDS is anticipated. Adapters make it possible to hook-up specific server side entities. Analogously, the Flex client defines a set of channels that blzeds depending on the type and format of communication.
All built-in adapter classes inherit from the ServiceAdapter abstract class. Behavioral Definition BlazeDS enables and facilitates: The binding of channels and endpoints to their implementation classes and their pairing is done in the services-config.

Besides, remoting the Spring messaging and security benefits also get extended to Flex applications. With these brief configuration examples in place, let’s explore BlazeDS’s pull-based or request-response based communication abilities.
B,azeds instances can be clustered and the following techniques can be applied to make applications scale better:. In web scale applications blazrds is an important criteria for success.
Select Java Project in the project type tree and click Next. BlazeDS can logically support both messaging domains. Sometimes, you may want to work with strongly typed objects.

PDF for easy Reference. Create the remoting destination A Remoting destination exposes a Java class that your Flex application can invoke remotely. The three alternative serverside message services in Spring BlazeDS are:.
The client sends a recurring request to the server at a predefined frequency. Many of these external systems and libraries, such as messaging infrastructure, database connections and stateless business services, lend themselves to pooling. The Proxy Service allows your Flex application to make cross-domain service requests in a secure and controlled manner. For beginners, it’s convenient, appropriate and advisable to get the latest release version of the binary turnkey distribution.
For accessing managed entities like Spring Beans or Enterprise Java Beans EJBsyou can use the JavaAdapter as the translator but you also need a custom factory to help you access these objects, as managed objects reside in a namespace separate from the one that BlazeDS uses to instantiate its own objects. Abstract classes not only define a contract like interfaces do but also define behavior through partial method implementations.
Robust Connection Non-blocking channels allow for greater number of connections to be served provided they are not all active at the same time always.
Java web application that leverages the Java Servlets specification. This is exactly what the Spring BlazeDS project implements.
A default configuration file, called services-config. BlazeDS is a Java Servlets based web application.
