Hi Friend

For pagination,try the following code:

<%@ page language="java" %>
<%@ page import="java.sql.*" %>
<%!
public int nullIntconvert(String str){
int num=0;
if(str==null) {
str="0";
}
else if((str.trim()).equals("null")) {
str="0";
}
else if(str.equals("")) {
str="0";
}
try{
num=Integer.parseInt(str);
}
catch(Exception e) { }
return num;
}
%>
<%
Connection conn = null;
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root";, "root");
ResultSet rs1 = null;
ResultSet rs2 = null;
PreparedStatement ps1=null;
PreparedStatement ps2=null;

int showRows=10;
int totalRecords=10;
int totalRows=nullIntconvert(request.getParameter("totalRows"));
int totalPages=nullIntconvert(request.getParameter("totalPages"));
int iPageNo=nullIntconvert(request.getParameter("iPageNo"));
int cPageNo=nullIntconvert(request.getParameter("cPageNo"));

int startResult=0;
int endResult=0;
if(iPageNo==0) {
iPageNo=0;
}
else{
iPageNo=Math.abs((iPageNo-1)*showRows);
}
String query1="SELECT SQL_CALC_FOUND_ROWS * FROM student limit "+iPageNo+","+showRows+"";
ps1=conn.prepareStatement(query1);
rs1=ps1.executeQuery();

String query2="SELECT FOUND_ROWS() as cnt";
ps2=conn.prepareStatement(query2);
rs2=ps2.executeQuery();
if(rs2.next()) {
totalRows=rs2.getInt("cnt");
}
%>
