Java Database Connectivity (JDBC)

I'm writing an app that connects to an Oracle database. Everything works fine when in the IDE (NetBeans by the way) but when I attempt to launch the jar file from the command-line I get the following error:

java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

From reading the other posts it seems like ojdbc14.jar is not in the classpath. But I've included ojdbc14.jar in the compile-time libraries in NetBeans. I've also tried to run the app like so:

java -classpath C:\ojdbc14.jar -jar PMA.jar

...but I still get the same error message. What's the way I need to do this so it'll work? Thanks!
