    Hi Florijan,

    I was involved with a Swing client/server project a while back that utilised
    the Remote Object Persistence part of Cayenne. We used ROP at its very early
    stage so we had a few niggling issues but overall I have to say I was/am very
    impressed with the speed at which one can setup the object model and get
    solid results.

    We were able to develop MVC patterns that allowed us to build custom widgets
    which were "wired" into Cayenne. Once we devised an event driven mechanism
    for exchanging data, all one would need to do is set a Cayenne object within
    the controller and staticly tell the widgets which properties they represent.
    Data input/output and validation is sent using events.

    I know that the team has since done a lot more work, especially with
    the 'trigger-like' functionality of Cayenne's ROP.

    The project took a fair amount of work but keep in mind that for most of the
    participants it was the first real Swing application and an extremely
    ambitious one at that. Cayenne integration took a fair bit of the development
    time but mostly because it was in its early stages and because we were (and
    the team still is) pushing the framework to its limits.

    I very strongly recommend Cayenne and ROP.

    Cheers,

    Marek Wawrzyczny
