- JSF Web Application
• JSP was great in its time. But as with everything, time
passed and other technologies were developed that
made it even easier to generate this same kind of
content, and on top of that, overcame many of the
limitations that were introduced with JSP.
• Enter JSF. It brings a graphical development mentality,
similar to Swing's, which relies on a set of reusable UI
components and event-driven approach.
• Instead of totally breaking away from its roots, JSF 2.0
can also be developed in the same way JSP is; in fact, a
JSF application is a JSP/servlets application.
• Typically, Web Applications are developed using the
MVC design pattern. This pattern works great with JSF
since, in a typical JSF application, the View is the page
we write, the Model is the data we wish to show, and the
Controller is the FacesServlet. Every request passes
through the FacesServlet. The configuration file for the
FacesServlet is faces-config.xml.

- What is Java EE?
• Java EE (Enterprise Edition) is a widely
used platform containing a set of
coordinated technologies that
significantly reduce the cost and
complexity of developing, deploying, and
managing multitier, server-centric
applications.
• Java EE builds upon the Java SE platform
and provides a set of APIs (application
programming interfaces) for developing
and running portable, robust, scalable,
reliable and secure server-side
applications. Đoàn Thiện Ngân Bài 6 - 5/22
- What is Java EE?
Fundamental components of Java EE include:
• Enterprise JavaBeans (EJB): a managed,
server-side component architecture used to
encapsulate the business logic of an
application. EJB technology enables rapid
and simplified development of distributed,
transactional, secure and portable
applications based on Java technology.
• Java Persistence API (JPA): a framework
that allows developers to manage data using
object-relational mapping (ORM) in
applications built on Đoàn
theThiện
Java Platform.

- JavaScript and Ajax Development
• JavaScript is an object-oriented scripting
language primarily used in client-side
interfaces for web applications.
• Ajax (Asynchronous JavaScript and XML)
is a Web 2.0 technique that allows
changes to occur in a web page without
the need to perform a page refresh.
• JavaScript toolkits can be leveraged to
implement Ajax-enabled components and
functionality in web pages.

- JavaServer Faces 2.1 CRUD
Application from a Database
http://netbeans.org/kb/docs/web/jsf20-crud.html
• View and modify data contained in the database -
otherwise referred to as CRUD (Create, Read,
Update, Delete) functionality. It relies on:
– JavaServer Faces (JSF) 2.0 for front-end web pages,
validation handling, and management of the
request-response cycle.
– Java Persistence API (JPA) 2.0 generates entity
classes from the database, and manage
transactions.
– Enterprise JavaBeans (EJB) 3.1, stateless EJBs that
access the entity classes, and contain the business
logic for the application.

- JavaServer Faces 2.1 CRUD
Application from a Database
• NetBeans IDE provides two wizards which
generate all of the code for the application.
– The first is the Entity Classes from
Database wizard which enables you to
generate entity classes from the provided
database.
– After creating entity classes, you use the
JSF Pages from Entity Classes wizard to
create JSF managed beans and EJBs for
the entity classes, as well as a set of
Facelets pages to handle the views for
entity class data.
