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

You're right, RT/classForName doesn't do initialization.
Does this work for you?:
(Class/forName "com.mysql.jdbc

I see the same problem trying to connect using the mysql driver. I
wonder if it might be a classloader issue.

I just realized that when I explicitly register the driver, there are

FYI Hans uploaded a manual.pdf to the files section of this group,

Oups... I knew I was making some stupid mistake here...
I need to do this instead:
user=> (enumeration-seq (. java.sql.DriverManager getDrivers))
([EMAIL PROTECTED])
user=> (java.sql.DriverManager/registerDriver (new
com.mysql.jdbc.Driver))
nil
user=> (enumeration-seq (. java.sql.DriverManager

I found a workaround...
I was able to register the driver using
-Djdbc.drivers=com.mysql.jdbc.Driver on the java command line.

user=> (enumeration-seq (. java.sql.DriverManager getDrivers))

You are trying to use a class where an instance of the class is
expected. You will need to .newInstance or equivalent.

Hi everyone,
I may look stupid but how do you cast Java arguments ?
