Ouf ! I'm not insane, (at least regarding this bug :)))
I just realized that when I explicitly register the driver, there are
now two instances begin added:
Clojure
user= (println (enumeration-seq (. java.sql.DriverManager getDrivers)))
([EMAIL PROTECTED]) ;; No instance registered
nil
user=

You're right, RT/classForName doesn't do initialization.
Does this work for you?:

Yep, Class/forName does the job.
I like the consistency of the JVM implementations (glup !), I run on
Ubuntu wih:
java version 1.6.0_03
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Server VM (build 1.6.0_03-b05, mixed mode)
I do have the mysql jar file in my classpath

(defmacro with-connection
Evaluates body in the context of a new connection to a database then
closes it. db-spec is a map containing string values for these
required
keys:

FYI Hans uploaded a manual.pdf to the files section of this group,
which is great. Thanks Hans. Very useful.

The mysql jdbc driver code says that it registers itself (static block)
but something is wrong.
Eventually I will find why but now I have other pressing needs
