JQuery DataTables And Java Integration

  • 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:
  • http://www.datatables.net/download/

  • 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);
     }
    
    }
