ServiceAdapter abstract class sits at the root of the hierarchy. To make the application more robust and better partitioned, modify the code as follows:. Only a couple of quick examples are vuide to give you a flavor the typical configuration elements. PDF for easy Reference. If you expand the zip file anywhere else make sure you adjust the path provided in these instructions accordingly.

Building a messaging application. Prior to the existence of this project developers relied on custom factories to integrate Spring and BlazeDS. The binding of channels and endpoints to their implementation classes and their pairing is guode in the services-config.

Getting started with BlazeDS

Channels themselves are configured in services-config. Integrating Adobe Flex and Java Learn about Adobe’s tool for guie together Flash platform-based interfaces with robust Java enterprise servers. Distributing work optimally between a client and its server is an important challenge when architecting RIA.

Management of the communication channels between Flex and Java. HTTP request-response Web services Gide procedure calls involving objects A possible demoting configuration could be as follows: Add event handlers guidd improve the application RemoteObject calls are asynchronous. Create the value object In the application so far, the list of products returned by the getProducts method is deserialized into dynamic objects.

BlazeDS’s demoting capabilities provide fast and efficient data transmission between a Flex client and a Java server with the help of the binary Action Message Format AMF protocol and the built-in endpoints, channels and adapters to support it. Although it’s mentioned upfront that BlazeDS helps connect Flash platform applications to Java, it’s important to define it a bit further.

BlazeDS – Wikipedia

When resources are pooled, they are shared over multiple clients. BlazeDS remoting services optimally combine a Flex client and a Java server and allow a developer to distribute workload across the wire in ways without necessarily glazeds the overheads that loose coupling like XML based interactions over HTTP and web services do.

Notice that there is no need to explicitly define a channel for the tutorial-chat destination. The Remoting Service allows your Flex application to directly invoke methods of Java objects deployed in your application server. The destination id is a logical name that your Flex application uses to refer to the remote class, which eliminates the need to hardcode a reference to the fully qualified Java class name.

Each endpoint defines a type and format of communication.

The other three are as follows: BlazeDS is a Java Servlets based web application. Therefore, multiple server-side messaging alternatives easily work with Flex messaging. In web scale applications scalability is an important criteria for success. Create the remoting destination A Remoting destination exposes a Java class that your Flex application can invoke remotely.

Ensure Use default location is selected. You cannot use the Flex Builder standalone configuration because it is built on top of a minimal version of Eclipse that does not include the Java development environment.

Set of services that can be managed using JMX agents. This section describes how to build a simple inventory management application that demonstrates the BlazeDS Remoting Service. Among others, the BlazeDS proxy capabilities have three important use cases including:. To work with typed objects in this application, first create the ActionScript version of the Product class created in step 1: The ProductDAO class provides the data access logic to retrieve and update products Products are transferred between the client and the server using Product objects value objects.

The goal of the turnkey server is to give developers an easy way to run samples out-of-the-box. They are the primary components that enable communication between these two entities. In this example, messages are published by Flex clients. Translation of Java objects returned from a server, in response to the remote method call, to corresponding AS3 objects. Besides, remoting the Spring messaging and security benefits also get extended to Flex applications.

Remoting-config, proxy-config and messaging-config contain configuration pertaining to remote procedure calls, proxy services and message services respectively. Flex clients use channels to connect to these endpoints.

To define the simple chat destination for this application:
