I read it was not ready for prime time yet - though I was hoping that it
will soon be ...
(simple queries and inserts work just fine now). Im not using Oracle as db
(if I had I guess the project would consider a few thousand dollars for a
commercial JDO peanuts :)

Interesting point about JDBC2.0 drivers. That sort of make tomcats pooling
obsolete then ?
Im using MySQL type 4 driver, Id better check this out then... Do you know
if they support pooling ? Can you show a snippet of repository.xml showing
this ?

Thanks !
