Sure.  Good goal, just not what I thought JDOM's goal was (somewhere on
the web pages or in the book, it gets billed as a "pure java" XML
implementation, with the implications that DOM ain't, and that it
should scale from small to large).

JNDI isn't actually hard to use (LDAP is a little painful).  I've spent
the last three weeks building a custom provider (for yet-another
enterprise API, JMS).  There's not much chance, in the environments in
which I work, that JSR-10 would be chosen over JNDI; the choice is
always likely to be JNDI with a custom provider (for standalone
deployment), able to use existing naming/directory installations.

[aside: normal usage of JNDI is on the order of Context context = new
InitialContext(); Preference preference =
(Preference)context.lookup("name");  But it scales mightily, with
increased need, including not only factories, but factories for
factories (at which the mind boggles) ... all optional]

So if JDOM is planning on being the lightweight alternative (don't use
for heavy lifting), then I'm prolly not in the right place.
