Oracle Fusion Middleware &

ADF

Agenda

Firstly What is Java ? Application Developer Framework (ADF) intro. Java Server Faces (JSF) intro. Short on ADF Faces. Using JSF/ADF Faces in a development . Q/A.

Who am I ?

Mohamed Shahpoup has my B.Sc. from FCI Mansoura Majored in computer science ,

Java Developer, Linux Admin, and JDeveloper/Java Instructor, that is besides my career as an java developer and freelancer. I have delivered large number of projects to many reputational companies like Vodafone, Etisalat, Nawras, AsiaCell, and Some international ministries. I worked as Java Instructor in many training centers since 2008.

Challenges Faced when Building J2EE Applications

Building J2EE applications can be complex. Development time can be extensive. Choosing and implementing appropriate design

patterns can be overwhelming. “Do it yourself” applications often repeat existing

application code. A large portion of “do it yourself” code is dedicated to

common tasks. The more code you write, the greater the chance of

errors. An application framework is needed.

Oracle Application Development Framework

Reduces the complexity of J2EE development by providing visual and declarative development

Increases development productivity– Less coding, more reuse– Focus on the application, not the “plumbing”

Provides a flexible and extensible environment by allowing multiple technology choices and development styles

Encourages J2EE best practices by implementing standard J2EE design patterns

Oracle ADFEnd-to-end J2EE Framework

Implements standard J2EE best practices Model-View-Controller (MVC) design pattern

Focus on the application, not the “plumbing” Consolidation and evolution of previous frameworks

Bindings: define how UI components use the values and actions in the data model

ADF Model Architecture

Decouples client and business service layers Client code contains no references to the

business service– Better design practice– Code is more maintainable

Architecture can be extended to add more types of business services

JavaServer Faces (JSF)Overview

Developed through Java Community Process as JSR 127

Nickname : Faces

Goal: Simplify creation of Java Server GUIs

Started: May 2001 First relase: March 2004 Oracle is a primary contributor

JavaServer Faces (JSF)Overview - Here is why!

JSF brings backing of a standard specification – JSR 127

JavaServer Faces (JSF)Overview

JSF is a natural evolution of J2EE Web development

Servlet API

JavaServer Pages

Custom Tag Libraries

JSTL

Too low level…

Easier but…scriptlets

Not standard…

Again, too low level…

JavaServer Faces

Finally, a comprehensive, standard API for J2EE Web applications!

JSF Architecture

UIComponent is rendered through Renderer class

Expression Language Value Binding is used to access managed bean also know as a "backing bean"

Managed bean accesses J2EE persistence layer

JavaServer Faces (JSF)Oracle ADF Faces

Built on top of JSF APIs A large component set >100 different components Far more advanced and interesting components

– Partial-page rendering, etc.

ADF model support out-of-the-box ADF Faces skins (Look and Feel)

ADF Databinding (JSR 227) Open Source per January 2006

ADF Faces also includes many of the framework features most needed by JSF developers today:

– File upload support is integrated at a component level

– Client-side validation is automatically derived from Validators and Converters for an improved user experience

– A pageFlow scope makes it easier to pass values from one page to another

– A new hybrid state saving strategy gives developers the best of both client and server-side state saving

JSF Architecture with ADF

EL accesses “bindings” object to value bind UI components

ADF “bindings” object is set through ADF Filter in web.xml

Bindings object accesses ADF Binding container, which then accesses DataControl

Business Services provide access to various data sources

Oracle Web-Logic Server

Oracle WebLogic Server is Oracle's preferred platform to provide both a standard Java EE environment and an environment specifically tailored to Oracle Fusion Middleware providing:

 Complete Java EE 5 compatibility   Complete Java SE 6 compatibility Web Services support Integration with Oracle's Fusion Middleware tools

Oracle Fusion MiddleWare

Oracle Fusion Middleware (OFM, also known as Fusion Middleware) consists of several software products from Oracle Corporation. OFM spans multiple services, including Java EE and developer tools, integration services, business intelligence, collaboration, and content management. OFM depends on open standards such as BPEL, SOAP, XML and JMS.Oracle Fusion Middleware provides software for the development, deployment, and management of service-oriented architecture (SOA). It includes what Oracle calls "hot-pluggable" architecture, designed to facilitate integration with existing applications and systems from other software vendors such as IBM, Microsoft.
