    Yes.

    #1 is created implicitly when you call
    DataContext.createDataContext(). That's the one returned from
    Configuration.getSharedConfiguration().

    #2 you will have to create yourself and store somewhere. E.g. in a
    ServletContext attribute.

    DefaultConfiguration conf = new DefaultConfiguration("my-cayenne.xml");
    // store it for the app duration soemwhere
    ...

    // later when you need a new context:
    Configuration conf = .. // get it from ServletContext or from where
    you put it
    return conf.getDomain().createDataContext();
