Thanks, Paul. I was just going to pipe in. I had the same problem
previously so I wrote a ParameterParser class where you can call just
int pos = parser.getIntParameter("Position");
It will throw an exception in case the param can't be converted to an
int, so you may want to simplify the code with
int pos = parser.getIntParameter("Position", DEFAULT_POSITION);
Paul gave the URL already. There's other goodies there, all covered in
the book. I'm working on enhancements for rev2 of the book, so if you
have suggestions...
