    Hi Kai,

    Your problem indeed points to an inconsistency in Cayenne in using
    bootstrapped ClassLoader - DataContext uses it, while ObjectId does
    not. I just fixed this and uploaded a patched 1.0.* version to
    preview.tar.gz . Let me know if this works for you.

    Still there is something strange with your environment, and I can't
    really tell what it is without having access to it. So is this a
    standalone app, or a J2EE container?

    This part is likely not related to the problems above.

    Your code for changing connection info look OK too me. It will work as
    long as you know the implications - namely, that the DataSource you are
    configuring in the code is *shared* by all users who obtain their
    DataContexts via the same instance of DataDomain.
