Displaying a resultset

Question

hey im new hear and fairly new to JSP. The thing is I want to display a list of records from a database in text boxes. When i open the JSP page the first record in the data base is displayed, when i press the "Last" button the last record in the database is displayed. Also when i press the "First" button the result set goes back to the first record. My problem is that the "Previous" and "Next" buttons dont work properly. The code in the JSP page is as:
<%@ page language = "java" contentType = "text/html"%>
<%@ page language = "java" import = "oracle.jdbc.driver.OracleDriver" %>
<%@ page language = "java" import = "java.sql.*" %>
<%@ page language = "java" import = "java.io.*" %>
<%@ page language = "java" import = "java.util.*" %>
<%@ page language = "java" import = "skip.*" %>
<%
     String Last = request.getParameter("Last");
     String First = request.getParameter("First");
     String Next = request.getParameter("Next");
     String Prev = request.getParameter("Previous");
     String l = (String)session.getAttribute("name");
     ResultSet rs = null;
     GetVenueDetails g = new GetVenueDetails();
     rs = g.getVenueDetails();
     String id = rs.getString("Venue_id");
     String venue = rs.getString("Venue_name");
     String addy = rs.getString("Address");
     String city = rs.getString("City");
     String country = rs.getString("Country");
     String cap = rs.getString("Capacity");
     if(First != null)
          rs.first();
          id = rs.getString("Venue_id");
          venue = rs.getString("Venue_name");
          addy = rs.getString("Address");
          city = rs.getString("City");
          country = rs.getString("Country");
          cap = rs.getString("Capacity");
     if(Last != null)
          rs.last();
          id = rs.getString("Venue_id");
          venue = rs.getString("Venue_name");
          addy = rs.getString("Address");
          city = rs.getString("City");
          country = rs.getString("Country");
          cap = rs.getString("Capacity");
     if(Next != null)
          rs.last();
          id = rs.getString("Venue_id");
          venue = rs.getString("Venue_name");
          addy = rs.getString("Address");
          city = rs.getString("City");
          country = rs.getString("Country");
          cap = rs.getString("Capacity");
     if(Prev != null)
          rs.previous();
          id = rs.getString("Venue_id");
          venue = rs.getString("Venue_name");
          addy = rs.getString("Address");
          city = rs.getString("City");
          country = rs.getString("Country");
          cap = rs.getString("Capacity");
%>
My java class is as follows:
package skip;
import java.sql.*;
import java.util.Properties;
public class GetVenueDetails
     static DBConnection DB = new DBConnection();
     Statement select;
     ResultSet result;
     Connection conn = DB.getConnection();
     public ResultSet getVenueDetails()
     Statement stmt = null;
          try
               stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
               result = stmt.executeQuery("select * from Venue");
               result.beforeFirst();
               result.next();
               System.out.println(result.getInt("Venue_id"));
          catch (SQLException e)
               System.out.print("SQL Exception " + e);
               System.exit(1);
     return result;
     public static void main(String args[])
          GetVenueDetails g = new GetVenueDetails();
          ResultSet rs;
          rs = g.getVenueDetails();
Ive seen a few similar questions on the site regarding such topics but i just cant make sence of them as i am new to JSP and only a college student. Any help would be appreciated.

Answer 1

hi paulPt,
firstly i would like to suggest dont write :--
String id = rs.getString("Venue_id");
String venue = rs.getString("Venue_name");
String addy = rs.getString("Address");
String city = rs.getString("City");
String country = rs.getString("Country");
String cap = rs.getString("Capacity");
and so on .... in each if block its doesnt looks good. use:-----
if(first!=null)
rs.first();
if(next!=null)
rs.next();
} and so on
and at the end write
String id = rs.getString("Venue_id");
String venue = rs.getString("Venue_name");
String addy = rs.getString("Address");
String city = rs.getString("City");
String country = rs.getString("Country");
String cap = rs.getString("Capacity");
Now Please tell me whats the ur problem is . Is it giving any error or throw any exception or it does not work at all . i will try my best
