To create a dynamic web project, you can read the following tutorial

Create a bean


Create Employee.java file inside the in.bushansirgur.jsf.beans package and add the following content

package in.bushansirgur.jsf.beans;

import javax.faces.bean.ManagedBean;

@ManagedBean
public class Employee {
	
	private String name;
	
	private String department;
	
	private String email;
	
	public Employee() {
	
	}
	
	public Employee(String name, String department, String email) {
		this.name = name;
		this.department = department;
		this.email = email;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getDepartment() {
		return department;
	}

	public void setDepartment(String department) {
		this.department = department;
	}

	public String getEmail() {
		return email;
	}

	public void setEmail(String email) {
		this.email = email;
	}
}

Create a Util class


Create EmployeeDataUtil.java file inside the in.bushansirgur.jsf.util package and add the following content

package in.bushansirgur.jsf.util;

import java.util.ArrayList;
import java.util.List;

import javax.faces.bean.ApplicationScoped;
import javax.faces.bean.ManagedBean;

import in.bushansirgur.jsf.beans.Employee;

@ManagedBean
@ApplicationScoped
public class EmployeeDataUtil {
	
	private List<Employee> employees;
	
	public EmployeeDataUtil() {
		loadSampleData();
	}
	
	public void loadSampleData() {
		employees = new ArrayList<>();
		
		employees.add(new Employee("Bushan", "IT", "[email protected]"));
		employees.add(new Employee("Bharatrh", "IT", "[email protected]"));
		employees.add(new Employee("Chaitra", "Sales", "[email protected]"));
	}
	
	public List<Employee> getEmployees() {
		return employees;
	}	
}

Note that we have added the @ApplicationScoped annotation to the class and this class shares the same data across the application

Create a Response page


Create dashboard.xhtml file inside the WebContent and add the following content

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
		xmlns:h="http://xmlns.jcp.org/jsf/html"
		xmlns:ui="http://xmlns.jcp.org/jsf/facelets">

	<h:head>
		<title>Dashboard</title>
	</h:head>
	
	<h:body>
		
		<h2>Employees List</h2>
		<hr/>
		<ul>
			<ui:repeat var="employee" value="#{employeeDataUtil.employees}">
				<li>#{employee.name} - #{employee.department} - #{employee.email}</li>
			</ui:repeat>
		</ul>
		
	</h:body>

</html>

Run the app


To run the application, right click on the project, select Run As -> choose Run on Server
