Well, the class is there at *compile time*. What this is telling you is that
at *runtime* Class.forName() will fail with that exception if the class is
not available *at runtime*. You need to catch the exception, like so:

try {
  Class.forName( "org.postgresql.Driver" );
} catch ( ClassNotFoundException cnfe ) {
  System.err.println( "driver not found!" );
}


I would recommend an introductory Java text.
