Java Error can't find the symbol

Hi I am trying to get a login information through the JSP's. I got an error Can't find symbol : Login while compiling LoginServlet.java

Here is my code, can you please tell the solution of that problem?

Login.java

 public class Login
{
public static boolean validate(String name, String pass) 
{       
    boolean status = false;
    Connection conn = null;
    PreparedStatement pst = null;
    ResultSet rs = null;

    String url = "jdbc:oracle:thin:@localhost:1521:xe";
    String driver = "oracle.jdbc.driver.OracleDriver";
    String userName = "system";
    String password = "dad";
    try 
      {
        Class.forName(driver).newInstance();
        conn = DriverManager.getConnection(url,userName, password);

        pst = conn.prepareStatement("select * from login where user=? and password=?");
        pst.setString(1, name);
        pst.setString(2, pass);

        rs = pst.executeQuery();
        status = rs.next();

    } 
catch (Exception e) 
   {
        System.out.println(e);
    } 
    finally 
        {
        if (conn != null) {
            try {
                conn.close();
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
        if (pst != null) {
            try {
                pst.close();
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
        if (rs != null) {
            try {
                rs.close();
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
    }
    return status;
}
}

LoginServlet.java

public class LoginServlet extends HttpServlet
{
private static final long serialVersionUID = 1L;

public void do Post(HttpServletRequest request, HttpServletResponse response)throws      ServletException, IOException
    {  
    response.setContentType("text/html");  
    PrintWriter out = response.getWriter();  

    String n=request.getParameter("username");  
    String p=request.getParameter("userpass"); 

    HttpSession session = request.getSession(false);
    if(session!=null)
    session.setAttribute("name", n);
    session.setAttribute("pass", p);

    if(Login.validate(n,p))
    {  
        Request Dispatcher rd=request.getRequestDispatcher("welcome.jsp");  
        rd.forward(request,response);  
    }  
    else
    {  
        out.print("<p style=\"color:red\">Sorry username or password error</p>");  
        Request Dispatcher rd=request.getRequestDispatcher("index.jsp");  
        rd.include(request,response);  
    }  

    out.close();  
}

}

import the Login class in to the LoginServlet.java . If both are in same package then you have to add it into class path.

it may be helpful for you. thanks

You need to import you Login class in your Servlet.

It might be due to your Login class and LoginServlet both are in different packages. So you need to import Login class in your LoginServlet, before using it.

You need to add something like,

import yourpackage.Login; in the beginning of the LoginServlet
