That's odd, because the only place that
string occurs in the code you posted is here:
And the getInitParameter() method of ServletConfig won't throw any exceptions, it just returns null if there's no such parameter configured. Also, usually there's a lot more to a stack trace than that. It would help if you posted the rest of it. And if you could scan your code for the string "jdbcDriver" to see what else might be printing that string which you didn't post here.
