Answer 1

i checked out all these things...the data is being retrieved from the database and the parameters being passed are also being assigned properly...the two values are not being compared properly and hence access is not allowed...the same code worked on a different system..here is the code....
the following is the servlet:
import java.io.IOException;
import java.io.PrintStream;
import java.sql.*;
import java.text.SimpleDateFormat;
import java.util.Date;
import javax.servlet.*;
import javax.servlet.http.*;
public class ELogin extends HttpServlet
    public ELogin()
    public void service(HttpServletRequest httpservletrequest, HttpServletResponse httpservletresponse)
        throws ServletException, IOException
        httpservletresponse.setContentType("text/html");
        java.io.PrintWriter printwriter = httpservletresponse.getWriter();
        String s  = httpservletrequest.getParameter("uid");
        String s1= httpservletrequest.getParameter("pw");
        String s2 = httpservletrequest.getParameter("dep");
        int i=1;       
        try
            HttpSession httpsession = httpservletrequest.getSession(true);
            Date date = new Date();
            SimpleDateFormat simpledateformat = new SimpleDateFormat("h:mm a");
            String s3 = simpledateformat.format(date);
            Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
            Connection connection = DriverManager.getConnection("jdbc:microsoft:sqlserver://localhost:3413;DatabaseName=Project", "Product", "product");
            Statement statement = connection.createStatement();
            ResultSet resultset1 = statement.executeQuery(" select * from emp_log ");
            boolean flag = false;
            do
                i++;
                if(!resultset1.next())
                    break;
                user1 = resultset1.getString(1);
                pass1 = resultset1.getString(2);
                Dep1  = resultset1.getString(3);
/* i think the problem is in the following part of the code*/
                if(s.equals(user1) && s1.equals(pass1) && s2.equals(Dep1))
                    javax.servlet.ServletConfig servletconfig = getServletConfig();
                    RequestDispatcher requestdispatcher = getServletContext().getRequestDispatcher("/Activity.jsp");
                    httpsession.setAttribute("Empname", s);
                    httpsession.setAttribute("Depname", s2);
                    httpsession.setAttribute("loginTime", s3);
                    httpsession.setMaxInactiveInterval(0x3938700);
                    requestdispatcher.forward(httpservletrequest, httpservletresponse);
                    flag = true;
            } while(true);
            if(!flag)
                String s4 = "Wrong Password,Please retype!!!";
                httpsession.setAttribute("DepError1", s4);
                httpsession.setMaxInactiveInterval(0x3938700);
                RequestDispatcher requestdispatcher2 = httpservletrequest.getRequestDispatcher("/ErrorPageForEmpLogin.jsp");
                requestdispatcher2.include(httpservletrequest, httpservletresponse);
        catch(Exception exception)
            System.out.println((new StringBuilder()).append("SQLException: ").append(exception).toString());
    static String user1;
    static String pass1;
    static String Dep1;
    static String DepErrorInEmp;
    static String DepErr;
    static String user2;
    static String pass2;
    static String Dep2;
    static String DepErrorInAdmin;
    static String DepErr1;
