JSF 2.0 Tutorial

jsf2-tutorials

JavaServer Faces (JSF) 2.0, is an MVC web framework which focus on simplifies building user interfaces (comes with 100+ ready UI tags) for Java web application and make reusable UI component easy to implement. Unlike JSF 1.x, almost everything is declared in faces-config.xml, with JSF 2.0, you are allowed to use annotation to declare navigating, managed bean or CDI bean, which make your development easier and faster.

In this tutorial, it provides many step by step examples and explanations on using JavaServer Faces (JSF) 2.0 framework.

Happy learning JSF 2.0 šŸ™‚

Quick Start

Some quick start examples for JSF 2.0

  • JSF 2.0 hello world example
    A JavaServer Faces (JSF) 2.0 hello world example, shows the JSF 2.0 dependencies, basic annotations and configurations. Let you have a quick idea about how JSF 2.0 look like, and also how it differs from JSF 1.x.
  • JSF 2.0 + Ajax hello world example
    In JSF 2.0, coding Ajax has been just like coding a normal HTML tag, itā€™s extremely easy. In this tutorial, you will restructure the last JSF 2.0 hello world example, so that, when the button is clicked, it will make an Ajax request instead of submitting the whole form.
  • How to make Eclipse IDE supports JSF 2.0
    Here’s a quick guide to show how to enable the JSF 2.0 features in Eclipse projects.
  • Resources (library) in JSF 2.0
    In JSF 2.0, all your resources files like css, images or JavaScript, should put into a ā€œresourcesā€ folder in the root of your web application. In JSF 2.0 terminology, all the sub-folder name of the ā€œresourcesā€ folder is considered as a ā€œlibraryā€ in JSF 2.0 web application. Later, you can reference this ā€œlibraryā€ with JSF tagā€™s library attribute.

Managed Bean

About managed bean configuration and injection in JSF 2.0

  • Configure Managed Beans in JSF 2.0
    In JSF 2.0, Java bean that can be accessed from JSF page is called Managed Bean. The managed bean can be a normal Java bean, which contains the getter and setter methods, business logic or even a backing bean (a bean contains all the HTML form value).
  • Injecting Managed beans in JSF 2.0
    In JSF 2.0, a new @ManagedProperty annotation is used to dependency injection (DI) a managed bean into the property of another managed bean.

Navigation

How the navigation works in JSF 2.0

  • Implicit Navigation in JSF 2.0
    Now, JSF 2 come out a new ā€œauto view page resolverā€ mechanism named ā€œimplicit navigationā€œ, where you donā€™t need to declare the above navigation rule, instead, just put the ā€œview nameā€ in the action attribute and JSF will find the correct ā€œview pageā€ automatically.
  • Conditional Navigation Rule in JSF 2.0
    JSF 2 comes with a very flexible conditional navigation rule to solve the complex page navigation flow.
  • JSF “form-action” navigation rule example
    In JSF navigation rule, you may encounter a situation where two separate actions return a same “outcome” in a page. In this case, you can use “form-action” element to differentiate the two navigation cases.
  • JSF : Page Forward vs Page Redirect
    By default, JSF performs a server page forward while navigating to another page. See following example to differentiate between the page forward and page redirect.

Resource Bundles

JSF’s message manipulation and Internationalization.

  • JSF 2.0 and Resource Bundles example
    In this tutorial, we show you the use of resource bundle to display the messages in the JSF 2.0. For maintainability concern, it’s recommended to put all the messages in the properties file, instead of hard-code the message in the page directly.
  • JSF 2 Internationalization example
    JSF 2.0 Internationalization or multiple language example.

JSF Tag Library

Standard JSF 2 form’s tag component.

Table Manipulation

Add, update, delete and sorting data in via JSF’s dataTable.

Facelets Tags

Doing layout template with JSF 2.0 facelets tags.

Converters & Validation

Standard Convertors and validator tags in JSF 2.0

Composite Components

Reusable components in JSF 2.0

Event Handler

JSF 2 comes with many event handler to hijack the JSF’s life cycle.

Integrate with Other Frameworks

  7. Will you people PLEASE quit using annotation beans in JSF. It is the worst of all bad ideas. It is hardcoding config data inside java source. Nothing could be worse.

    If you have only a few years experience in programming, PLEASE do not write these blogs.

  9. Hello, I have a quick question about icefaces tag outputResource. I am trying to remove icefaces completely out of my projects and use myfaces instead, can you give me an equivalent implementation of ice:outputResource in myfaces, it could be a myface tag or equivalent implementation using html and js that i could use. Also checked tomahawk, trinidad component libraries for this.

    Reply

  10. Hello, Just my personal preference but I have a strong negative thinking about annotations. To me this is what we call “hard-coding” which I believe should be avoided at all cost. Using xml configuration the server doesnt have to be restarted.

    All configuration should be table/xml driven. Other wise you have to re-generate the war file and re-install it for the smallest of changes. Not practical, and goes against the entire principal of JSF.

  18. Can u please tell me the difference between Backing Bean and Manged Bean ?
    Is both are same ..?
    Can you explain with an example.
    Please replay ..

    Reply

    2. Both are used interchangeably usually. But as such managed beans contain data for the screen, while backing beans hold references of components of the screen. You may not need to hold the references of components on the screen in a backing bean if you don’t plan to add components dynamically. If it all sounds too complicated then you can simply assume that both are same.

  20. Hi, Please consider me as your new fan. I am starting a new J2EE financial project which will also have lots of menus, graphs, charts. I was thinking using JSF2 with PrimeFaces, do you think that is a good approach or is any other MVC a preferred framework of choice (Spring MVC or something else). Many thanks in advance.

  53. I just started reading, I found many grammatical errors which make me wonder if I should go on. Simple reasons like this tells me if sample codes provided are in fact accurate as well or will just confuse me.

    Reply

    1. I am not too concerned about grammar issues on a site like this. I am assuming that those that you found were there not because the lack of education, but because English is not the first language learned. I know several brilliant people that still struggle with a few of the English grammer. I am also glad to be recieving help from people around the world.

      I am looking more at the comments listed earlier for determining the relavance of this site. Read on within the comment list if you want to determine if this site is worth going on. I am looking more at this.

    Hi Mr. Yong,

    I am fully impressed by your passion and expertise in the areas you (or you guys) are providing the professional tutorials.

    Could you provide me the experience to create and maintain such a kind of website ? Don’t worry, my area is dealing in the area of science and Christian, such as 3+1 space and time, uncertainly in quantum mechanics, DNA innovation, math and science (theoretical physics, more specifically).

    Are u using JSF+Spring+Hibernate + MySQL integration or some more efficient way ?

        Problem:
        I had try to put a function or validator at the end of bean class used by the faces-config.xml. In place of authentication failed it should come back to jsf page but it’s currently going to spring section

  72. Hi
    I’m desperately looking for help because to my knowledge I’m out of options.. I tried searching forums, google my problems with jsf2 but nothing fits to what I’m facing šŸ™‚
    I found Your blog very, if not the most inspiring during my search for tutorials with jsf2. From this place I’ve learned about configuration specifics necessary to set up development environment, which in my case is eclipse + tomcat 7. I managed to get some of Your code and made a few simple classes just to make myself understand this part of java world better… but here I ran into a problem, which made me stuck in one place.
    Here’s what I have:
    -Simple class in which arraylist of strings is initialized and filled with some static values.
    -Xhtml page, in which I have one column dataTable with a header.

    What I want is:
    -Make the mentioned class a managed bean, returning an arraylist.
    -Have the xhtml page with a dataTable filled with a content of an arraylist from managed bean.

    I know it sounds crazy to ask for such basics, but I had to cut down all my previous work to an atomic level, just to see where the problem lies.

    I made a class in a package called demo. The code of the class looks like below(it’s a simplified version of one oh Your examples):

    package demo;

import java.util.ArrayList;
import java.io.Serializable;

import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;

@ManagedBean(name="userList")
@ViewScoped
public class UserList implements Serializable {
	private static final long serialVersionUID = 1L;
	private ArrayList<String> users;

	@PostConstruct
	public void create() {
		users = new ArrayList<String>();
		users.add("John");
		users.add("Charley");
		users.add("Priscila");
		users.add("Kate");
		users.add("Emily");
		users.add("Barack");
		users.add("Mia");
		users.add("Arthur");
	}

	public ArrayList<String> getUsers() {
		return users;
	}
}

    and the code of the xhtml file looks like this:

    <?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:f="http://java.sun.com/jsf/core"
	xmlns:h="http://java.sun.com/jsf/html"
	xmlns:p="http://primefaces.prime.com.tr/ui">
<f:view>
	<h:head>
		<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
		<title>User List 2</title>
	</h:head>
	<body>
		<h:form>
			<h:dataTable value="#{userList.getUsers}" var="user">
				<h:column>
					<f:facet name="header">User</f:facet>
				</h:column>
				<h:column>
					<h:outputText value="#{user}" />
				</h:column>
			</h:dataTable>
		</h:form>
	</body>
</f:view>
</html>

    The problem is ā€“ I don’t get any output from the bean. What I get is just a column name.
    To be clear, I stayed away from touching faces-config.xml ā€“ this file has no entries besides it’s default content.

    My configuratoin seems to be ok and tomcat does not generate any exceptions nor any extra output during page start/refresh.
    I have all libs in place eg WebContent/WEB-INF/jstl-api and jstl-impl. Project Facets in project properties is checked and MyFaces are selected to be included in the application.

    Can You please help me?

  75. …please, am having a challenge with how to upload a file; I tried the examples given in the PrimeFaces documentation, yet, ActionListener event wont fire. Please, help me out. Below is the code:

    	<p:fileUpload fileUploadListener="#{fileUploadController.handleFileUpload}" 
		allowTypes="*.jpg;*.png;*.gif;" description="Images"/>		

    public class FileUploadController {
	
	private Logger logger = LoggerFactory.getLogger(FileUploadController.class);

	public void handleFileUpload(FileUploadEvent event) {
		logger.info("Uploaded: {}", event.getFile().getFileName());

		FacesMessage msg = new FacesMessage("Succesful", event.getFile().getFileName() + " is uploaded.");
		FacesContext.getCurrentInstance().addMessage(null, msg);
	}
}

    1. Hi,

      I just found the solution for your problem. It took me days to found the solution because there isn’t any documentation :/

      You just need to include this in your web.xml:

      PrimeFaces FileUpload Filter
      org.primefaces.webapp.filter.FileUploadFilter

      PrimeFaces FileUpload Filter
      Faces Servlet

      Enjoy it! :p

      Reply

      1. sorry about xml lol

        <filter>
	<filter-name>PrimeFaces FileUpload Filter</filter-name>
	<filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
</filter>
<filter-mapping>
	<filter-name>PrimeFaces FileUpload Filter</filter-name>
	<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>

    2. hi i’m facing the primeface uploading problem.

  79. I am hoping with your vast knowledge of JSF 2.0, you will be able to help.

    I am looking for a link / site where I can find out which all tags can make up a particular tag.

    For example, we can include a graphicImage tag in a commandLink tag.

    Is there a place where ALL JSF 2.0 tags and what other tags they can contain has been listed?

    Thank You,
    A B

    1. “javax.el.ELException: /page1.xhtml @16,8 value=ā€#{customer.getCustomerList()}ā€:”

      i think u have to corrct this only

      plz change ‘#{customer.getCoustomerList()}’ to

      “#{customer.coustomerList}” if it is a private member or a public function in a customer bean class.

  85. Man, I would like to thank you for those amazing tutorials. I’ve been searching for this kind of information for a long time, but it doesn’t exists elsewhere, even in Mojarra or MyFaces sites. Most of information is not for newbies, they’re so technical…

    Thanks a lot, you have a new friend!
