help, i am just wondering why am i having an error with this program....
package hall;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
/** Simple servlet that reads three parameters from the form data.
* Part of tutorial on servlets and JSP that appears at
* http://www.apl.jhu.edu/~hall/java/Servlet-Tutorial/
* 1999 Marty Hall; may be freely used or adapted.
*/
public class ThreeParams extends HttpServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String title = "Reading Three Request Parameters";
out.println(ServletUtilities.headWithTitle(title) +
"<BODY>\n" +
"<H1 ALIGN=CENTER>" + title + "</H1>\n" +
"<UL>\n" +
" <LI>param1: "
+ request.getParameter("param1") + "\n" +
" <LI>param2: "
+ request.getParameter("param2") + "\n" +
" <LI>param3: "
+ request.getParameter("param3") + "\n" +
"</UL>\n" +
"</BODY></HTML>");
}
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}
the error is something like,
ThreeParams.java:20:cannot find symbol
symbol: variable ServletUtilities
location:class hall.ThreeParams
out.println(ServletUtilities.headWithTitile(title) +
^
something like that, i do know that the package hall could be the problem, but where can i find that package and where do i put it. thank you. and about this program(that i saw in http://www.apl.jhu.edu/~hall/java/Servlet-Tutorial/), well, i really need it as a reference, that is why i need to work on this one. once again, thank you...
