Java Servlet class can not find the bean class

Question

I have created a servlet file 'LoginServlet.java' and a bean file 'SimpleBean.java' and placed them in a same folder.When i compiled the bean file it compiled successfully but when i compile the servlet file i get error 'cannot find symbol' and it indicates the bean class which i instantiated inside the servlet class.

LoginServlet.java

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.RequestDispatcher;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServlet;
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.*;
import java.util.*;

public class LoginServlet extends HttpServlet {

    public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
        response.setContentType("text/writer");
        PrintWriter pw = response.getWriter();
        String name = request.getParameter("username");
        String password = request.getParameter("password");
        String code = request.getParameter("code");
        SimpleBean bean = new SimpleBean();
        //admin login
        if (name.equals("admin") && password.equals("admin")) {
            RequestDispatcher rd = request.getRequestDispatcher("adminservlet");
            rd.forward(request, response);
        } else { //general login
            try {
                Class.forName("com.mysql.jdbc.Driver");
                Connection con = DriverManager.getConnection("jdbc:mysql://localhost/" + code, "root", "");
                PreparedStatement pst = con.prepareStatement("SELECT * FROM demo_teacher WHERE name = ?");
                pst.setString(1, name);
                ResultSet rs = pst.executeQuery();
                if (rs.next()) {
                    HttpSession session = request.getSession(true);
                    session.setAttribute("user", name);
                    ArrayList rows = new ArrayList();
                    do {
                        List row = new ArrayList();
                        row.add(rs.getString("name"));
                        row.add(rs.getString("login_time"));
                        row.add(rs.getString("logout_time"));
                        rows.add(row);
                    } while (rs.next());
                    request.setAttribute("resultSet", rows);
                    RequestDispatcher rd = request.getRequestDispatcher("profile.jsp");
                    rd.forward(request, response);
                } else {
                    RequestDispatcher rd = request.getRequestDispatcher("index.jsp");
                    rd.forward(request, response);
                }
            } catch (Exception ex) {
                ex.printStackTrace();
            }
        }
    }
}

    public void setName(String n) {
        name = n;

Since you are compiling from the command line, review your classpath. Ensure it contains the directory where the .class files are being stored (in this case, it is the current directory):

set CLASSPATH=.;%CLASSPATH%
