ENTERPRISE FLEX WITH BLAZEDS PDF

The Networking Architecture of BlazeDS BlazeDS provides a clean separation of the Selection from Agile Enterprise Application Development with Flex [Book]. In this example I am going to use Spring+BlazeDS integration API for integrating backend Spring based J2EE layer into client layer Flex. So the User Interface is produced using Flex and to take care of the remoting we can use BlazeDS which is Open Source from Adobe. BlazeDS.

With these brief configuration examples in place, let’s explore BlazeDS’s pull-based or request-response based communication abilities.

BlazeDS remoting services optimally combine a Flex client and a Java server and allow a developer to distribute workload across the entterprise in ways without necessarily imposing the overheads that loose coupling like Hlazeds based interactions over HTTP and web services do. The RTMP specification was proprietary until the beginning of this year and has most recently been opened enterpriise to public.

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. During serialization, the serializer eagerly fetches all the JPA and Hibernate persistent objects and sends them across the enterpries.

Remoting and messaging program that can be extended by using its Java API. For effective near real-time messaging use one of the following channels: Hi Ravi, I am looking for security, with springs and blazeds, which will connect to database and validate the user and password and maintains the session.

This streamlines BlazeDS web application deployment. To enable the spring integration these classes needs to be configured in the services-config file. Now after this initial project setup steps move to J2EE layer development.

Number; public var countryName: If the accessed data is not changing during the course of its reuse it always makes sense to cache it. July 16, at After completing this tutorial you can make your own enterprise application, and with Oracle WebLogic you won’t have to worry about the performance or availability of your balzeds.

Abstract classes not only wkth a contract like interfaces do but also define behavior through partial method implementations. As data from a BlazeDS server leaves for the Flex client, it can be intercepted using the familiar Java Servlet filter mechanism.

Distributing work optimally between a client and its server is an important challenge when architecting RIA. In the above class I have used these three basic Spring annotation tag:.
