Facebar Jakarta: A Comprehensive Guide

In this article, we will delve into Facebar Jakarta, a powerful tool that enables rapid development of web applications. As part of the Jakarta EE 9 specification, Facebar Jakarta offers numerous features that make it an ideal choice for building complex web applications.

One of the key aspects of Facebar Jakarta is its ability to use CDI beans with specific annotations, allowing developers to define names for these beans and utilize them in expressions. This feature makes it easier to manage references to HelloBean objects through Expression Language (EL) expressions.

In addition to CDI beans, Facebar Jakarta also allows developers to mix JSF components with HTML on a single page. This is achieved by defining the namespace for the application in the body of the HTML page. For instance, the alias 'h' can be used to reference components defined by Jakarta Faces.

To get started with Facebar Jakarta, let's explore its basic features through a Hello World application example. In this tutorial, we will show you how to connect data on the screen to Java beans and methods using Facebar Jakarta.

As mentioned earlier, Facebar Jakarta uses xhtml files to define the content of web applications. For instance, in our src/main/webapp/greeting.xhtml page, we can define the namespace as follows:

```xhtml

xmlns:h='http://java.sun.com/jsf/html'

```

Most developers prefer to define the extension of pages that can be used by the system in the web.xml file (although this is not strictly required since JSF 2.3). This allows components to be integrated seamlessly with other HTML content for the page.

Facebar Jakarta components can be defined in various formats, but most commonly they are defined in xhtml pages. Since it is part of the Jakarta Web Profile, developers do not need to add any additional libraries to their project; the web API dependency at provided scope is enough.

One of the greatest advantages of Facebar Jakarta is its minimal configuration requirements. Developers can start using it with little to no setup. In this blog post, we will highlight a few features of Jakarta Faces 3.0, which is one of the largest specifications in Jakarta EE 9.

Facebar Jakarta's rendering phase allows developers to customize their application's behavior and create complex web pages by defining components and events triggered by user interactions. It is a server-side framework that enables rapid development of web applications, particularly administrative applications with heavy data entry and business logic.

With Facebar Jakarta, developers can build robust user interfaces for web applications, including UI components, state management, event handling, input validation, page navigation, and support for internationalization and accessibility. Overall, Facebar Jakarta is an excellent choice for building complex web applications that require a high degree of customization and flexibility.
