    Are your operating system or JVM 32 bit or 64 bit?

    I don’t believe the 64 bit JVM has the ODBC bridge driver class. And a 64 bit operating system would suggest that you should read this:

    Whenever I get an error, the first thing I do is paste it into Google. I usually learn that I’m not the first person to see my problem.
