Well the error reported is a NullPointerException in the
initializer for the driver you're trying to use. So clearly the driver
class is loaded (that is, you haven't put the JAR in the wrong place or
something). It's a little hard to say what is null in the initializer for
the driver (I think <clinit> means a static initializer, right?). But I
suspect this is a type 2 JDBC driver, meaning it requires some native
libraries which may not be available when you run it in jBoss. Can you
confirm that? If it is instead a type 3 or 4 JDBC driver, then perhaps
it's looking for configuration files or something? Too bad it's not open
source - you could just look up the line in the code... :)
