Since I don't use JBuilder myself, here are some general debugging tips.
- Check your CLASSPATH and make sure both the .jar files are visible.
- See if you have to configure JBuilder separately for using any binary/jar files( refer to JBuilder documentation ).
- Try using one of the sample programs that come with your download using command line compiling/running and see if that works.
Hope that helps!
