JSF 2.0 Tutorial

Posted: May 7, 2012 in JSF + Hibernate

JavaServer Faces (JSF) 2.0, is a 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 are declared in faces-config.xml, with JSF 2.0, you are allowed to use annotation to declared navigation, managed bean or CDI bean, which make your development more easier and faster.

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

Happy learning JSF 2.0 🙂

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 different from JSF 1.x.
  • JSF 2.0 + Ajax hello world example
    In JSF 2.0, coding Ajax is just like coding a normal HTML tag, it’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 project.
  • Resources (library) in JSF 2.0
    In JSF 2.0, all your resources files like css, images or JavaScript, should put into a “resources” folder in the root of your web application. In JSF 2.0 terminology, all the sub-folder name of the “resources” folder is consider as a “library” in JSF 2.0 web application. Later, you can reference this “library” with JSF tag’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.


How navigation works in JSF 2.0

  • Implicit Navigation in JSF 2.0
    Now, JSF 2 come out a new “auto view page resolver” mechanism named “implicit navigation“, where you don’t need to declare the above navigation rule, instead, just put the “view name” in the action attribute and JSF will find the correct “view page” 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 is perform 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 properties file, instead of hard-code the message in the page directly.
  • JSF 2 internationalization example
    JSF 2.0 internationalization or multiple languages 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.

JSF, update hibernate

Posted: May 1, 2012 in JSF + Hibernate

I can’t update my entity. I am using Hibernate and JSF 1.2 with Eclipse. This is my DAO:

public void updateTimesheet(Timesheet timesheet) {

And this is the bean:

public String doUpdate() {
    SessionFactory factory=new Configuration().configure().buildSessionFactory();
    Session session2= factory.getCurrentSession();
    timesheet=(Timesheet) dataModel.getRowData();
    return "ok";

And this is my getDataModel() method:

public DataModel getDataModel() {
    Session session2 = UtilHibernate.getSession();
    dataModel.setWrappedData(session2.createQuery("from Timesheet").list());
    return dataModel;
