Just to add some perspective (and hopefully not to confuse things
further), our direction in Cayenne 3.1 is towards scenario #2, and
getting rid of #1 completely. This way a user decides where his
Cayenne stack (or multiple Cayenne stacks) is stored and how it is
accessed.

Yes.
I am not sure how to initialize.
#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();
