<%
int pageSize = 5;//No of Records Shown in a Page
int pageCount=0; // Total No of Pages
int recordCount=0; // Total No of Records in the DataBase
int startNo=0; // Starting Record to be displayed.
int endNo=0; // End No to be displayed
int pageNo=0; // Page No
int i=0; // Used in forLoop
int count = 0;//to count record number
if(request.getParameter("Page")!=null)
session.setAttribute("Page",request.getParameter("Page"));
if(session.getAttribute("Page") == null)
pageNo=1;
else
pageNo=Integer.parseInt(session.getAttribute("Page").toString().trim());
sql = "Select * from threadeddiscussion b where b.tdIdSystem='"+id+"' and b.tdStatus=0 and b.userID='"+username+"' and TO_DAYS(NOW())-TO_DAYS(b.tdDate)<=90 order by b.tdID desc";
rs = stmt.executeQuery(sql);
while(rs.next())
count++;
recordCount = count;
if (pageNo>1 && recordCount<=pageSize*(pageNo-1))
pageNo=pageNo-1;
session.setAttribute("Page",Integer.toString(pageNo));
if (recordCount!=0)
pageCount = recordCount/pageSize;
if(recordCount%pageSize!=0) pageCount++;
startNo = ((pageNo-1) * pageSize) + 1;
endNo = (pageNo==pageCount) ? recordCount : (pageNo * pageSize);
rs = stmt.executeQuery(sql);
if (recordCount!=0){
for(i=1; i<startNo; i++)
rs.next();
while((rs.next()) && (startNo<=endNo)){
startNo++;
rs.getString();
