Jquery DataTables is a open source plugin for creating tables in browser.
It has many features like sorting,server side processing, JQUERY UI theme rolling.
The download link for this plugin:

In this demo we have shown integration of data table with java.The Data table will load the data by making an Ajax call to load all the data.
The response data must contain ‘aaData’ properties.
The main components in this demo are :

Project Structure:

Integration With Java :

The Static data StudentDataService.java ,

package com.sandeep.data.service;

import java.util.ArrayList;
import java.util.List;
import com.sandeep.data.object.Student;

public class StudentDataService {

 public static List<student> getStudentList() {

  List<student> listOfStudent = new ArrayList<student>();

  Student aStudent = new Student();

  for (int i = 1; i <= 200; i++) {

   aStudent = new Student();

   aStudent.setName('Sandeep' + i);

   aStudent.setMark('20' + i);

   listOfStudent.add(aStudent);
  }

  return listOfStudent;

 }
}

Data table object which will go as response in Servlet DataTableObject.java,

package com.sandeep.data.object;

import java.util.List;

public class DataTableObject {

 int  iTotalRecords;
 
 int  iTotalDisplayRecords;
 
 String  sEcho;
 
 String sColumns;
 
 List<student> aaData;

 public int getiTotalRecords() {
  return iTotalRecords;
 }

 public void setiTotalRecords(int iTotalRecords) {
  this.iTotalRecords = iTotalRecords;
 }

 public int getiTotalDisplayRecords() {
  return iTotalDisplayRecords;
 }

 public void setiTotalDisplayRecords(int iTotalDisplayRecords) {
  this.iTotalDisplayRecords = iTotalDisplayRecords;
 }

 public String getsEcho() {
  return sEcho;
 }

 public void setsEcho(String sEcho) {
  this.sEcho = sEcho;
 }

 public String getsColumns() {
  return sColumns;
 }

 public void setsColumns(String sColumns) {
  this.sColumns = sColumns;
 }

 public List<student> getAaData() {
  return aaData;
 }

 public void setAaData(List<student> aaData) {
  this.aaData = aaData;
 }
 
 
 
}

The Servlet which return JSON as String StudentDataServlet.java,

package com.sandeep.json.data.servlet;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import com.sandeep.data.object.DataTableObject;
import com.sandeep.data.object.Student;
import com.sandeep.data.service.StudentDataService;

public class StudentDataServlet extends HttpServlet {

 private static final long serialVersionUID = 1L;

 public StudentDataServlet() {
  super();
 }

 protected void doGet(HttpServletRequest request,
   HttpServletResponse response) throws ServletException, IOException {

  response.setContentType('application/json');
  PrintWriter out = response.getWriter();
  List<Student> lisOfStudent = StudentDataService.getStudentList();
  
  DataTableObject dataTableObject = new DataTableObject();
  dataTableObject.setAaData(lisOfStudent);
  
  Gson gson = new GsonBuilder().setPrettyPrinting().create();
  String json = gson.toJson(dataTableObject);
  out.print(json);

 }

 protected void doPost(HttpServletRequest request,
   HttpServletResponse response) throws ServletException, IOException {

  doGet(request, response);
 }

}

The html file with table element file ajaxDataTable.jsp,

Java Script code for initializing the data table my-demo-table-script.js,

$(document).ready(function() {

    $('.jqueryDataTable').dataTable( {
        'bProcessing': false,
        'bServerSide': false,
        'sAjaxSource': './StudentDataServlet',
        'bJQueryUI': true,
        'aoColumns': [
            { 'mData': 'name' },
            { 'mData': 'mark' }
            
        ]
    } ); 
} );
