As far as I understand, you would have to compile MM.Mysql with 
different Java environments for different subdirectories, as e.g. the 
JDBC-1-parts do only compile with JDBC-1-libraries, and those are only 
part of Java 1.1. Newer Java versions contain JDBC-2 or even JDBC-3, and 
while those are (more or less) API-compatible with earlier versions, 
they are not compatible in the internals. So, the compiler is stumbling 
over incompatible interface definitions, missing declarations, wrong 
parameters and all this sort of things.

I have never compiled the driver myself due to this reason - I was just 
too lazy to figure out. I simply take the precompiled thing and 
repackage it (read: attach signature) to fit my needs.

Perhaps someone can give advise which directory to compile with what? 
There must be a way... ;-)

Best regards,
Dirk
