    Hello all

    I am currently thinking about using Cayenne ROP with bleeding edge
    Cayenne 3. I like the idea to use the functionality of web services
    without the pain of web services. There is only one problem for which I
    hope somebody has an answer or solution (or idea).

    My application currently runs an embedded Derby database. The decision to
    use Derby as an embedded DB was because like that the user does not need
    to install and maintain a database server. I always had the idea that when
    running the tool in a multi user environment we could switch from the
    embedded database to a database server without any problem. Theoretically
    this is true. Practically JDBC is a problem in some environments.

    So here is my problem. While I would like to keep the embedded database
    for single user scenarios, I would also like to use ROP for multi user
    environments.

    Can I implement both and switch from one to the other mechanism with a
    simple (to be implemented) configuration switch? From what I read in the
    documentation Hessian uses a new ObjectContext? That is probably the easy
    part. But what about client and server code in the client? Can I mix this?
    Or is there some simple trick?

    Thanks for your help.

    Cheers,
    Adrian
