Look at:
http://www.technobuff.net/javatips/kits/startkit/classes_ifs_pkgs.shtml
and
http://cs.stmarys.ca/~porter/csc/465/notes/javapl_packages.html

then check out
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/appdev/deployment.html

This should explain a few things.

Hi,

      Thanks for the help,The HelloServlet.java file is as follows

/*****************HelloServlet.java*******************/
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

/** Simple servlet used to test server.
 *  <P>
 *  Taken from Core Servlets and JavaServer Pages 2nd Edition
 *  from Prentice Hall and Sun Microsystems Press,
 *  http://www.coreservlets.com/.
 *  &copy; 2003 Marty Hall; may be freely used or adapted.
 */

public class HelloServlet extends HttpServlet {
  public void doGet(HttpServletRequest request,
                    HttpServletResponse response)
      throws ServletException, IOException {
    response.setContentType("text/html");
    PrintWriter out = response.getWriter();
    String docType =
      "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 " +
      "Transitional//EN\">\n";

    out.println(docType +
                "<HTML>\n" +
                "<HEAD><TITLE>Hello</TITLE></HEAD>\n" +
                "<BODY BGCOLOR=\"#FDF5E6\">\n" +
                "<H1>Hello</H1>\n" +
                "</BODY></HTML>");
  }
}


/*****************HelloServlet.java*******************/

Hoping to get going with it.

Thanks
AS
