Load JDBC Driver via URLClassLoader

Hi all,

I have a small problem with loading my JDBC driver. For a couple of reasons, I cannot put the jar(s) on the classpath, but in a configuration file. After reading this file, I create a URLClassLoader including all the jars that are listed in the config file. Then I call Class myDriverClass = Class.forName(<driverName>, true, myUrlClassLoader), which finds, loads and even instantiates the driver class trough the newInstance() method without the slightest problem. Only DriverManager.getConnection() keeps on throwing SQLExceptions telling me "No suitable driver" ...

Any ideas regarding how I can make the DriverManager know my driver?

Thanks for any advice,

Freddy Wong
