    EJB 3.0 integration in FDS, with Annotations

    busitech Level 1
      We have been working with the EJB 3.0 implementations and see a lot of synergy between the new approach to enterprise Java with this new specification, and would love to see FDS add an adaptor to support it.

      Our new entity/session beans have annotated relationships, primary key information, and security regarding access to the object and it's methods are specified already in the Java source. Centralized management of this information where it is closest to the source is highly productive.

      With so much of the FDS configuration still sitting in static XML files, we are required to maintain a redundant copy of all of the annotation information separately. This adds pure overhead to the development process, and it is challenging to keep the two in sync when applications are enhanced.

      We would like to see the FDS framework more tightly integrated with the rest of the J2EE world, and through Java introspection and annotations learn about the applications available on the server side without custom config files.

      The fill, assembler, and synchronization methods could simply be a standard class interface to be implemented with methods to override, or even annotated with flex annotations. Destinations would no longer need to be hand-configured. The meta-data about row identity would be read from the entity beans themselves. If a fill method has parameters, read them from the function prototypes.

      (The existing Flash remoting product seems to have the above features. We enjoy the integration of Flash Remoting, and the development workflow associated. The Flash client only needs the JNDI name of the services, and once authenticated, access to any function is possible without further action. FDS goes above and beyond to provide several very interesting features, but is not quite as intuitive when it comes to J2EE services.)

      To tie this meta-information on the server back to the IDE for visual design, using real server-side object properties and methods, and session bean functions would close the loop on the development cycle. This could also be accomplished within Eclipse since the server side Java classes could easily be in the classpath. The IDE could give the developer a hand in choosing and referencing valid return object properties. An actionscript object could even be generated if necessary from the entity bean's properties...

      Are any of these ideas in the works, or are there any exisiting methods for accomplishing these efficiencies?
