How to retrieve records from a database and display it in a jsp page.Help!!

Question

Hello everyone ! im very new to this forum.Please help me to solve my problem
First i ll explain what is my requirement or needed.
Actually in my web page i have text box to enter start date and end date
and one list box to select the month .If user select or enter the dates in text box
accordingly the data from ms access database has to display in a jsp page.
Im using jsp and beans.
I tried returning ResultSet from bean but i get nothing display in my web page
instead it goes to error page (ErrorPage.jsp) which i handle in the jsp.
I tried many things but nothing work out please help me to attain a perfect
solution. I tried with my bean individually to check whether the result set has
values but i got NullPointerException . But the values which i passed or
available in the database.
I dint get any reply for my last post please reply atleast to this.
i get the date in the jsp page is by this way
int Year=Integer.parseInt(request.getParameter("year"));
int Month=Integer.parseInt(request.getParameter("month"));
int Day=Integer.parseInt(request.getParameter("day"));
String startdate=Day+"/"+Month+"/"+Year;
int Year1=Integer.parseInt(request.getParameter("year1"));
int Month1=Integer.parseInt(request.getParameter("month1"));
int Day1=Integer.parseInt(request.getParameter("day1"));
String enddate=Day1+"/"+Month1+"/"+Year1;But this to check my bean whether it return any result!
public void databaseConnection(String MTName,String startDate,String endDate)
try
         java.text.SimpleDateFormat dateFormat=new java.text.SimpleDateFormat("dd/MM/yyyy");
         java.util.Date fromDate=dateFormat.parse(startDate);
        java.util.Date tillDate=dateFormat.parse(endDate);          
        java.sql.Date sqlFromDate=new java.sql.Date(fromDate.getTime());
        java.sql.Date sqlTillDate=new java.sql.Date(tillDate.getTime());
          String query1="select MTName,Date,MTLineCount from Main where MTName='"+MTName+"'  and Date between '"+sqlFromDate+"' and '"+sqlTillDate+"' " ;
        System.out.println(query1);
          Class.forName(driver);
         DriverManager.getConnection(url);
         preparedStatement=connection.prepareStatement(query1);
         preparedStatement.setString(1,"MTName");
          preparedStatement.setDate(2,sqlFromDate);
          preparedStatement.setDate(3,sqlTillDate);
          resultSet=preparedStatement.executeQuery();           
           while(resultSet.next())
                    System.out.println(resultSet.getString(1));
                    System.out.println(resultSet.getDate(2));
                    System.out.println(resultSet.getInt(3));
        catch (Exception e)
         e.printStackTrace();
I Passed value from my main method is like thisl
databaseConnection("prasu","1/12/2005","31/12/2005");Please provide solutions or provide some sample codes!

java.text.SimpleDateFormat dateFormat=new java.text.SimpleDateFormat("dd/MM/yyyy");
         java.util.Date fromDate=dateFormat.parse(startDate);
        java.util.Date tillDate=dateFormat.parse(endDate);          
          String query1="select MTName,Date,MTLineCount from linecountdetails where mtname='"+MTName+"'  and Date >='"+fromDate+"' and Date <='"+tillDate+"' " ;
        System.out.println(query1);
//From main method
databaseConnection("prasu","1/12/2005","31/12/2005");I got the output as
