There are cool software tools and there are practical tools. People who make their living by developing enterprise Web applications are very careful in selecting the language or technology for their needs. There is a huge difference in requirements for developing an application like Google maps and the enterprise-grade high availability business applications. Anatole Tartakovsky of Farata Systems (pictured) is one of these programmers who know pretty much everything. He lives and breathes programming. If he does not know the answer to your problem today, he'll know it tomorrow. Flex Developer's Journal have asked Anatole some tough questions that concern most of the enterprise developers who are considering Adobe Flex 2 as a tool for their next Web application.Q. How hard is it for typical Java EE developer with Struts and DAO skills to add Flex to their skill set?
A. I would say, the hard part is over. Flex allows seamlessly integrate your Web client with the Java server code of any flavor – POJO, Hibernate/Spring or JMS, so the server-side part remains relatively unchanged. Struts developers will find coding states in Flex a great simplification over Struts model – yet yielding fantastic user interface. Flex piggybacks on Java EE and browser technologies, so any experienced Java programmer will be able to correlate his current skills with the development process in Flex. Java and ActionScript 3 are very similar, Eclipse is a familiar environment for many developers. Tools, deployment techniques, security, performance tuning – everything can be reused.
Q. How Flex 2 technology addresses security issues?
A. The server-side security management is quite extensive, and it allows you to use either containers' offerings or custom security providers via declarative XML binding. There are couple of challenges as Flex supports multiple protocols, so Java EE security that relies only on the HTTP sessions has to be extended, but it is simple and well documented process. On the client side, it builds on Flash player security that is known for its lack of serious security flaws. You have a built-in security manager that has all standard protection for cross-domain and zone access. Corporations can further restrict code they receive from 3rd parties by wrapping the code loaders in additional security managers.
