Servlet cannot invoke package classes

Question

I have two class which is authenticateController and userAuthentication store in authencation package with path WEB-INF/class/authentication/.
My jvm is unable compile authenticateController in authentication directory but it is not problem in path WEB-INF/class/.
authenticateController.java
package authentication;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
import authentication.*;
public class authenticateController extends HttpServlet {
     //Initialize global variables
     public void init() throws ServletException {
     public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          doPost(request,response);   
     public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          //RequestDispatcher dispatcher = request.getRequestDispatcher("userAuthentication");
          //dispatcher.forward(request,response);     
          String usrnme = request.getParameter("usrnme");
          String password = request.getParameter("password");
          userAuthentication obj = new userAuthentication(usrnme, password);
          if(obj.getResult()) {
               HttpSession session = request.getSession();
               session.setAttribute("authenticateUser",usrnme);
               response.sendRedirect("/developmentLine/userId/authentication/queryresult.jsp");
          else {
               response.sendRedirect("/developmentLine/userId/authentication/login.jsp");
     //Clean up resources
         public void destroy() {
}Any problem in my code?

ok, this is compile error msg. I am using notepad and window cmd to compile. I able compile in classes directory (/WEB-INF/classes/) but once i move it into authentication subdirectory (/WEB-INF/class/authentication/), the authenticateController occur error msg as below.
C:\WebJsp\servletlibrary\WEB-INF\classes\authentication>javac authenticateController.java
authenticateController.java:28: cannot find symbol
