Java Development News:
Flex Integration with J2EE
By Steven Webster and Alistair McLeod
01 Apr 2004 | TheServerSide.com
In Chapter 20 of “Developing Rich Clients with Macromedia Flex”, attention is turned to the Data Service features of Macromedia Flex and the MXML markup language that allow business logic deployed within a J2EE application server to be integrated with a rich-client interface delivered to the browser using MXML markup.
In addition, Webster and McLeod discuss a number of design patterns and techniques that will be familiar to J2EE developers from the Core J2EE Pattern catalogue, showing how these patterns can be implemented using the ActionScript 2.0 programming language, allowing the development of Rich Internet Applications using techniques and methods that will be instantly familiar to the J2EE development community.
Developing Rich Clients with Macromedia Flex
It is widely accepted that the Internet has not yet delivered on the online promise; web applications have extended the reach of enterprises to customers, offering anywhere and anytime access. However, this has been at the expense of the overall user-experience, which is diminished by delivery through the web browser. Rich Internet Applications address this problem, by coupling the ubiquity, small-footprint and interactive capabilities of the Flash Player with server-side technologies such as J2EE and .NET, to deliver highly effective and intuitive applications. What has been missing so far is a way for traditional enterprise software developers to deliver these Rich Internet Applications using familiar technologies that fit within their existing development workflow.
Enter Macromedia Flex: a presentation server solution that provides an XML-based language MXML for describing rich-client interfaces, and integrating them with new and existing infrastructure deployed within a J2EE or .NET environment. If you have ever developed dynamic enterprise web application with technologies like JSP or ASP, you should have no problem transferring those skills to developing rich-client solutions with Flex.
By splitting the discussion of Flex into presentation, business and integration tiers, authors Steven Webster and Alistair McLeod explore the software feature by feature, building towards the development and deployment of a typical real-world Flex application. More than a reference manual, the book is full of worked examples, and aims to impart real-world development experience of building large-scale applications using Macromedia Flex, with discussion of topics including design patterns, strategies for technical architecture, and integrating Flex with your existing applications.
- Learn to develop rich-client interfaces using MXML and ActionScript 2.0
- Learn to build scalable, maintainable and performant Flex applications with a focus on design patterns and architectural strategies
- Deliver rich-client applications upon new and existing J2EE and .NET technical infrastructure
- Authors Steven Webster and Alistair McLeod are recognized leaders in the Rich Internet Application development community, for their frequent contributions to the software engineering of Enterprise RIAs, and have worked with the Flex product since its initial stages of development.
Combo tutorial and reference provides both the technological grounding and real-world know-how needed to deliver rich-client interfaces and interactive experiences with Flex.
