Pagination in JSP

We can create pagination example in JSP easily. It is required if you have to display many records. Displaying many records in a single page may take time, so it is better to break the page into parts. To do so, we create pagination application.

In this pagination example, we are using MySQL database to fetch records.

We have created "emp" table in "test" database. The emp table has three fields: id, name and salary. Either create table and insert records manually or import our sql file.

index.jsp

view.jsp

<%@ page import="java.util.*,com.javatpoint.dao.*,com.javatpoint.beans.*" %>
<%
String spageid=request.getParameter("page");
int pageid=Integer.parseInt(spageid);
int total=5;
if(pageid==1){}
else{
	pageid=pageid-1;
	pageid=pageid*total+1;
}
List<Emp> list=EmpDao.getRecords(pageid,total);

out.print("<h1>Page No: "+spageid+"</h1>");
out.print("<table border='1' cellpadding='4' width='60%'>");
out.print("<tr><th>Id</th><th>Name</th><th>Salary</th>");
for(Emp e:list){
	out.print("<tr><td>"+e.getId()+"</td><td>"+e.getName()+"</td>
<td>"+e.getSalary()+"</td></tr>");
}
out.print("</table>");
%>
<a href="view.jsp?page=1">1</a>
<a href="view.jsp?page=2">2</a>
<a href="view.jsp?page=3">3</a>
