Simone Tripodi commented on DBUTILS-96:
---------------------------------------
OK I figured out that {{DriverManager}} is not able to manage {{Driver}}
instances that were not loaded by the system {{ClassLoader}}, see [Pick your
JDBC driver at runtime |http://www.kfu.com/~nsayer/Java/dyn-jdbc.html].
If no objections, I could work on a patch to DbUtils to work around that
problem.
Bill, WDYT? TIA!
