It's a basic servlet...
Here is the code:

public class techSupportServlet extends HttpServlet {
  String driver;

  public void init() throws ServletException {
    driver = getServletConfig().getInitParameter("driver");

  }

  protected void doPost(HttpServletRequest req, HttpServletResponse res)
          throws ServletException, IOException {

Owdy,
If you have an invalid web.xml, tomcat will tell you on startup that it
can't parse it.  Otherwise, you should be able to retrieve init
parameters after the servlet is initialized.  Post your servlet's
relevant code.
