JSF - Using DataModel in a DataTable

In this section, we'll showcase the use of datamodel in a dataTable.

Example Application

Let us create a test JSF application to test the above functionality.

Step Description
1 Create a project with a name helloworld under a package com.tutorialspoint.test as explained in the JSF - Display DataTable subchapter of JSF - DataTables chapter.
2 Modify UserData.java as explained below.
3 Modify home.xhtml as explained below. Keep the rest of the files unchanged.
4 Compile and run the application to make sure the business logic is working as per the requirements.
5 Finally, build the application in the form of war file and deploy it in Apache Tomcat Webserver.
6 Launch your web application using appropriate URL as explained below in the last step.


package com.tutorialspoint.test;

import java.io.Serializable;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.model.ArrayDataModel;
import javax.faces.model.DataModel;

@ManagedBean(name = "userData", eager = true)
public class UserData implements Serializable {
   private static final long serialVersionUID = 1L;

   private static final Employee[] employees =  new Employee[] {
      new Employee("John", "Marketing", 30,2000.00),
      new Employee("Robert", "Marketing", 35,3000.00),
      new Employee("Mark", "Sales", 25,2500.00),
      new Employee("Chris", "Marketing", 33,2500.00),
      new Employee("Peter", "Customer Care", 20,1500.00)

   private DataModel<Employee> employeeDataModel 
      = new ArrayDataModel<Employee>(employees);

   public DataModel<Employee> getEmployees() { 
      return employeeDataModel;

      <h2>DataTable Example</h2>
         <h:dataTable value = "#{userData.employees}" var = "employee"
            styleClass = "employeeTable"
            headerClass = "employeeTableHeader"
            rowClasses = "employeeTableOddRow,employeeTableEvenRow">
               <f:facet name = "header">Sr. No</f:facet>
               #{userData.employees.rowIndex + 1}
               <f:facet name = "header">Name</f:facet>    				
               <f:facet name = "header">Department</f:facet>
               <f:facet name = "header">Age</f:facet>
               <f:facet name = "header">Salary</f:facet>

Once you are ready with all the changes done, let us compile and run the application as we did in JSF - First Application chapter. If everything is fine with your application, this will produce the following result.
