I didn't mention that part :-)
Obviously, there's no point in tomcat calling the
doGet/doPost methods - they're meant to be
passed in data about the calling browser etc.,
and output an HTML page. That just doesn't
make sense in the "load-on-startup" situation.
You define (actually, over-ride) the init method of
the servlet instead, like this:
public void init(ServletConfig config) throws ServletException
{
super.init(config);
// put your startup code here, like creating java objects and
// putting them in the application context where all jsp pages
// and other servlets can get at them.
//
// eg
//
// ServletContext context = config.getServletContext();
// SystemState systemState = new SystemState();
// context.setAttribute("systemState", systemState);
}
This is all documented in the sun java servlet specifications...
