I'm new to the list ...

I'd like to know where can i found the source of the jdbc driver for
postgresql (the jdbc7.0-1.2.jar)

--hermann

PS : Is anyone here using postgres with jBoss (minerva as pool connection
manager)? I really have a strange problem : when i perform "update" query on
the base via a pooled connection from minerva, it is throwing exception,
while everything works fine with "insert" or "select". I wonder if something
in the driver (like auto-commit or anything else) may cause this problem. My
guess : Auto-commit is set to true in a "update" query, so that when minerva
tries to end the transaction by commiting it, exceptions get thrown.
