This excerpt describes the process of creating a complete Flex-Java distributed application. Upgrading Flex applications to Java Enterprise Edition applications is done with Flex Data Services. FDS provides transparent access to POJO, EJBs, and JMS and comes with adapters for frameworks like Spring and Hibernate. These powerful capabilities come free for a single-CPU server, otherwise see your local Adobe dealer. Flex can also invoke any SOAP Web Service or send an HTTP request to any URL via Web Services and HTTPService components. Here we will illustrate Flex controls, HTTPService, RemoteObject, and Consumer via two versions of a stock portfolio application. The first version will show communications between Flash and a plain old Java object (POJO) using Flex remoting. We'll also explain how to use the HTTPService to read the RSS news feed. In the other version w... (more)

Introducing Enhanced Flex Components from Clear Toolkit Framework

The goal of this article is to give you a brief overview of some of the objects from clear.swc, which is a part of the open source Clear Toolkit framework available at https://sourceforge.net/projects/cleartoolkit. Component library clear.swc includes a number of enhanced Flex components that software engineers of Farata Systems have been developing and using during the last three years in many enterprise projects. To better understand brief explanations given in this document, we strongly recommend to check out the source code from Sourceforge CVS repository and examine the sourc... (more)

Developing Intelligent Web Applications With AJAX (Part 2)

The publicity that AJAX grabbed over the last half a year is based on closing the gap between the Web applications and the desktop applications, combining the "reach" and "rich." At the same time, the gap between the technological level of AJAX and what corporate developers expect in their modern arsenal is really astonishing. After all, AJAX is neither a tool nor a platform. There is no AJAX standards committee or community process in place. While software vendors are crafting proprietary development platforms on top of AJAX (which pretty much means "from scratch"), early adopte... (more)

SOA and RIA Together: Developing with Adobe Flex and Java

Rich Internet Applications are perfect for consuming enterprise services. As SOA evolves toward reusable components that can be accessed inside and outside of the corporate intranets, they need to provide outside developers with customizable pre-built components that can be easily integrated in composite applications. Adobe's Flex/Flash platform offers unique opportunities in both richness of the environment and global deployment accessibility. In this session we will uncover all the layers of successful SOA integration for RIA applications - including communication, customizatio... (more)

Flex Best Practices: DTO is the Horseshoe of your Flex Application

Remember this old little rhyme? For want of a nail, the shoe was lost; For want of the shoe, the horse was lost; For want of the horse, the rider was lost; For want of the rider, the battle was lost; For want of the battle, the kingdom was lost; And all for the want of a horseshoe nail. This little poem often comes to my mind as a see increasing number of amateurs perceiving Flex as yet another "library of controls".  The fact is, it is very easy to start coding in Flex. So much that hot-heads get on the coding spree before noticing that Flex is a beautifully crafted framework with pro... (more)
