JSF password example

A full JSF 2 example to render a password input field via <h:inputSecret /> tag.

1. Managed Bean

A simple managed bean, with a “password” property.

package com.mkyong.form;
 
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import java.io.Serializable;
 
@ManagedBean
@SessionScoped
public class UserBean implements Serializable {
 
	private String password;

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

}

2. View Page

Two pages for the demonstration.

demo.xhtml – render a password field via “h:inputSecret”, button via “h:commandButton”, if the button is clicked, password value will be submitted to the “userBean.password’ property via setPassword() method, and forward to “user.xhtml”.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"   
      xmlns:h="http://java.sun.com/jsf/html">

    		Password : <h:inputSecret value="#{userBean.password}" />
    		<h:commandButton value="Submit" action="user" />
    	  </h:form>
 
    </h:body>
</html>
