Radio Buttons Example with JSF 2.0

So today, we ‘re gonna talk about radiobuttons’ integration together with JSF 2.0 and Eclipse IDE. In JSF, we can use the h:selectOneRadio tag, in order to create a radiobutton like input element.

For example, assume the following JSF code:

<h:selectOneRadio value="#{user.favoriteBMW}">
   	<f:selectItem itemValue="335" itemLabel="BMW 335" />
   	<f:selectItem itemValue="316" itemLabel=" BMW 316" />
   	<f:selectItem itemValue="M3 SMG" itemLabel="BMW M3 SMG" />

The afore-mentioned code is somehow translated to our familiar HTML format, with JSF to autoembedding the whole selectOneRadio‘s structure into a proper HTML table. Indeed, JSF cares about style. One more thing, before getting into code: There are 3 possible ways that let us render radiobuttons, according to h:selectOneRadio:

  1. By hardcoding the values into f:selectItem tag.
  2. By generating values (using a Java Map) and putting them into f:selectItem tag.
  3. By generating values (using an Object array) and putting the into f:selectItem tags; then, we have to represent the value with a var attribute.

1. Backing Bean

Here is our Backing Bean that holds the submitted data:


package com.javacodegeeks.enterprise.jsf.radiobuttons;

import java.io.Serializable;
import java.util.Map;
import java.util.LinkedHashMap;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;

public class UserBean implements Serializable{

	private static final long serialVersionUID = 7134492943336358840L;

	String favoriteCar1, favoriteCar2, favoriteCar3;

	public String getFavoriteCar1() {
		return favoriteCar1;

	public void setFavoriteCar1(String favoriteCar1) {
		this.favoriteCar1 = favoriteCar1;

	public String getFavoriteCar2() {
		return favoriteCar2;

	public void setFavoriteCar2(String favoriteCar2) {
		this.favoriteCar2 = favoriteCar2;

	public String getFavoriteCar3() {
		return favoriteCar3;

	public void setFavoriteCar3(String favoriteCar3) {
		this.favoriteCar3 = favoriteCar3;

	//generated by Map
	private static Map<String, Object> car2Value;
		car2Value = new LinkedHashMap<String, Object>();

		car2Value.put("BMW 335", "335"); //label, value
		car2Value.put("BMW 316", "316");
		car2Value.put("BMW M3 SMG", "M3 SMG");

	public Map<String, Object> getFavoriteCar2Value()
		return car2Value;

	//generated by Object array
	public static class Car
		public String carLabel;
		public String carValue;

		public Car(String carLabel, String carValue)
			this.carLabel = carLabel;
			this.carValue = carValue;

		public String getCarLabel(){
			return carLabel;

		public String getCarValue(){
			return carValue;


	public Car[] car3List;
	public Car[] getFavoriteCar3Value()
		car3List = new Car[3];

		car3List[0] = new Car("BMW 335", "335");
		car3List[1] = new Car("BMW 316", "316");
		car3List[2] = new Car("BMW M3 SMG", "M3 SMG");

		return car3List;

2. JSF Pages

The first page will display the three fore-mentioned JSF radiobutton techniques:


 <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
<html xmlns="http://www.w3.org/1999/xhtml"    
      xmlns:f="http://java.sun.com/jsf/core" >

    	<title>JSF RadioButtons Example</title>

    	<h1>JSF 2 RadioButtons Example</h1>

    		1. Hardcoded with "f:selectItem" :
    		<h:selectOneRadio value="#{user.favoriteCar1}">
    			<f:selectItem itemValue="335" itemLabel="BMW 335" />
    			<f:selectItem itemValue="316" itemLabel="BMW 316" />
    			<f:selectItem itemValue="M3 SMG" itemLabel="BMW M3 SMG" />


    		2. Generated by Map:
    		<h:selectOneRadio value="#{user.favoriteCar2}">
    			<f:selectItems value="#{user.favoriteCar2Value}" />


    		3. Generated by Object Array; access with "var"
    		<h:selectOneRadio value="#{user.favoriteCar3}">
    			<f:selectItems value="#{user.favoriteCar3Value}" var="c"
    				itemLabel="#{c.carLabel}" itemValue="#{c.carValue}"	/>


    		<h:commandButton value="Submit" action="response"/>
    		<h:commandButton value="Reset" type="reset"/>

And the second one, will return the submitted data:


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
<html xmlns="http://www.w3.org/1999/xhtml"    

    	<h1>JSF 2.0 RadioButton Example - Response Page</h1>

    		<li>user.favoriteCar1 : #{user.favoriteCar1}</li>
    		<li>user.favoriteCar2 : #{user.favoriteCar2}</li>
    		<li>user.favoriteCar3 : #{user.favoriteCar3}</li>
