Sure:
public void init(ServletConfig config)
throws ServletException {
// Always call super.init
super.init(config);
message = config.getInitParameter("message");
if (message == null) {
message = defaultMessage;
}
try {
String repeatString = config.getInitParameter("repeats");
repeats = Integer.parseInt(repeatString);
} catch(NumberFormatException nfe) {
// NumberFormatException handles case where repeatString
// is null *and* case where it is something in an
// illegal format. Either way, do nothing in catch,
// as the previous value (1) for the repeats field will
// remain valid because the Integer.parseInt throws
// the exception *before* the value gets assigned
// to repeats.
}
}
it's form the book "core Servlets..." by Marty Hall

Howdy,
Can you post your init() method?
Does getServletConfig().getInitParameter("message") return null?
What does getServletConfig().getInitParameterNames() return?
