I have been happily using Derby for two years within IntelliJ Idea, but have now hit a wall trying to deploy the application I developed. I have tried setting the path to derby.jar on the command line and/or in the CLASSPATH environment variable to no avail. The embedded driver doesn't load; the error message is, "No suitable driver found for jdbc:derby:EMDatabase;create=true". I'm under Windows XP Pro. Any help would be appreciated.
