Thanks, now I got loads and loads of debug output, so I'm still confused, albeit on a higher level... :)

I have added /opt/jakarta/ant/lib/ant.jar to the CLASSPATH, but that didn't help either. I don't know what to make of these "Could not load class (org.apache.tools.ant.*" messages...

Okay, so I guess if all else fails, I'll give up on building the driver myself and use the official pre-compiled one.

Thanks for your help!

Kind regards,
