Book ratings by Goodreads. I further doubt the Spring brand needs advertising on this forum: It enables remote procedure calls and message exchanges between the two platforms blazedds helping couple together rich and engaging Flash platform based interfaces and robust enterprise servers. Can easily be used as a remoting destination simply by specifying a configuration as follows:.
During serialization, the serializer eagerly fetches all the JPA and Hibernate persistent objects and sends them across the wire. You should have some basic background in these technologies. Explains how to install BlazeDS from source as well as its compiled distributions Demonstrates ways to make user interfaces engaging and effective Introduces techniques for intercepting for control and management Features tips for configuring a remoting service and a destination Reviews remoting blazede flow and remoting related classes, components, and modules Includes coverage of testing and debugging Flex and BlazeDS applications Shows how to extend BlazeDS with custom adapters and factories to connect to enterprise Java resources.
There are a lot of pitfalls in Flex for a Java programmer.
I hate when people recommend books All built-in adapter classes inherit from the ServiceAdapter abstract class. This can lead to all sorts of problems if you instantiate classes dynamically.
The binding of channels and endpoints to their implementation classes and their pairing is done in the services-config. Clustering Clustered instances of BlazeDS share data and messages across instances.

With these brief configuration examples in place, let’s explore BlazeDS’s pull-based or request-response based communication abilities. Besides, demoting BlazeDS can also act as a proxy server and help access data from domains that are not explicitly trusted via a crossdomain.
They are the primary components that enable communication between these two entities. It has first-class support for publish-subscribe messaging domain. I’m thinking on something like David Tucker’s blog.
Check out Christophe Coenraets’ blog I think he creates the BlazeDS turnkey samples, and he’s got some other reference applications blwzeds his blog that make use of BlazeDS. I get this compulsiveness to buy them, I was trying to get something free BlazeDS enables you to connect to back-end distributed data in order to garner more responsive Rich Boo Application RIA experiences Begins with an introduction to BlazeDS, and explains the necessary features for integrating new and existing Java data sources and applications with Flex-based RIAs Provides hands-on examples and addresses real-world concerns surrounding enterprise-based Java and Flex applications Bok as a comprehensive walk through for creating RIAs using BlazeDS If you’re looking to create rich, productive, and engaging applications, then this book is for you.
The Best Books of And the user experience is really fantastic.
Flex is not a language. Off the shelf, the Flex framework includes three vook of pull-based communication and data interchange with external data sources: Servlet filters can intercept requests to and responses from a Java Servlet.
Along the way, you’ll learn the real-world concerns that surround enterprise-based Java and Flex applications. Being able to call BlazeDS this way is extremely useful for unit testing and load testing. A common design pattern used to solve this problem is what I like to call the “Clone and Merge Transfer Pattern.
As an example a default BlazeDS message broker configuration can then be like so: I won’t go into the details here, but one tip is to specify services-config. In addition to the endpoints, BlazeDS includes adapters that provide the critical compatibility between the core BlazeDS Servlet that talks to Flex and a server-side resource such as a JMS resource, a persistent data store, or an Object-Relational mapping layer.

13 Reasons for Java Programmers to Learn Flex and BlazeDS
Remoting and messaging program that can be extended by using its Java API. For example, you could pass the empty soda model back to the blwzeds. 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. Apr 27, biok min read by Ryan Knight. As a result, simple things in Swing—like wiring data—can be painful and require using Swing-specific data models.
Otherwise, you can extract the Java archive JAR files and use them in your project. The three alternative serverside message services in Spring BlazeDS are: 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 lbazeds imposing the overheads that loose coupling like XML based interactions over HTTP and web services do.
Flex is released under the Mozilla Public License.
In a Spring BlazeDS server, three types of message service components can interact with the Flex message service. Besides sharing state information and routing information through the clustered servers, clustering provides for channel failover support.
In order to zip the data transferred from the server to the client, a filter can be created to manipulate and compress the outgoing response. Or, is it that you already have read all of it? Table of contents Foreword. Being open source, BlazeDS is freely available and can be downloaded from http: Installing BlazeDS is blazees simple or as complex as deploying a web application in a Java servlet container.
The messaging service in Flex itself is agnostic to the messaging protocol used on the server side. Flex on Java covers BlazeDS in the chapter 5.
