Oracle ADF Code Corner

product logo

Oracle ADF Code Corner
The Oracle ADF Code Corner is a weekly blog-style column from the source that helps Oracle ADF developers to go beyond drag and drop in their Oracle ADF web application development. The idea is to provide code examples to real-world coding challenges that developers can use and integrate in their projects.

Most of the code examples below are inspired by frequently asked questions posted on the OTN JDeveloper forum [JDeveloper] [JDeveloper 11].

All samples are provided as they are with no guarantee for future upgrades or error corrections. No support can be given through Oracle customer support. Please post questions or problems related to the samples on this page to one of the OTN JDeveloper forums referenced above.

Oracle ADF and Oracle JDeveloper 11g

Application Development becomes Easier !

Two new books published by Oracle Press help application developers to get started and become professional in building Rich Internet Applications (RIA) with Oracle JDeveloper and the Oracle ADF and Fusion development platform. Both books are written by members of the Oracle JDeveloper and ADF product management team and provide a wealth of information, as well as hints and tips that compliment the Oracle product documentation.

The "Oracle JDeveloper 11g Handbook" by Duncan Mills, Peter Koletzke and Avrom Faderman provides an entry to Fusion development for developers that are new to Oracle JDeveloper and the ADF platform, or who have a background in 4GL tools, like Oracle Forms.

The "Oracle Fusion Developer Guide" by Frank Nimphius and Lynn Munsinger, assumes some understanding of basic ADF and Java EE development principles and takes you to the next level. It is considered an advanced book that provides a fast track to application development with Oracle ADF and goes beyond the dominant drag and drop development gesture in Oracle JDeveloper and ADF.

Though not a requirment, adding both books to your bookshelf equips you with a throughout understanding and skill set to become professional in Oracle ADF application design and development.

Oracle JDeveloper 11g Handbook

A Guide to Oracle Fusion Web Development

By Duncan Mills, Peter Koletzke , Avrom Roy-Faderman
ISBN 0071602380
Released in October 2009

This Oracle Press guide shows how to build Web applications using the Fusion Middleware development tool, Oracle JDeveloper. The book discusses the latest technologies and explains how to develop code using multiple techniques.

Oracle JDeveloper 11g Handbook: A Guide to Fusion Web Development covers the Oracle Application Development Framework and JavaServer Faces. Hands-on practice examples walk you through the creation of a complete sample application that employs highly-interactive user interface components and declarative development methods. You will learn the techniques required to implement Fusion-oriented software solutions in JDeveloper

Oracle Fusion Developer Guide

Building Rich Internet Applications with Oracle ADF Business Components and ADF Faces

By Frank Nimphius, Lynn Munsinger ISBN 0071622543 Release in January 2010 (pre-orderable)

In the thoroughly explained examples throughout this Oracle Press guide, you will find the shortest path to success in developing for the Oracle Fusion environment. Oracle Fusion Developer Guide covers common problems and use-cases, providing code and explanations that ultimately make you more productive from the start. The book delivers the vital knowledge necessary to become a skilled ADF and ADF Faces Rich Client application developer.

Oracle JDeveloper 11g and ADF

The ADF Faces Rich Client component set is a collection of Ajax enabled JavaServer Faces components that make development of interactive web applications as easy as drag and drop. Though as much as we want it and as much as it is our mission to make development easy, not everything can be exposed to developers in a drag and drop gesture. Sometimes a bit of Java programming and know how is required to unleash the real power of ADF Faces RC components, and this is what this section of the ADF Code Corner is about. The primary focus for the examples is set to the Fusion Development platform that includes ADF Business components as the persistence layer, ADF for the binding, ADFc as the controller and ADF Faces RC as the view layer.

In addition to the technologies just mentioned, service integration with SOA services also falls within this scope. As much as possible though We will try to simplify the demonstrated testcase and reduce calls to web services to POJO equivalents to ensure that the provided sample workspaces run in a stand alone environment with no strings attached that would require a bigger installation of the Fusion Middleware software.

This section complements the written how-to documents on ADF Code Corner. Though a written how-to seem to be preferrable, some samples are easier to record than to write up. Samples that appear in this section will either be too short for a written version or too long. The individual recording length is limited to a minimum so it can be watched while enjoying a small cup of coffee during a mini break.

	A Rough Guide to using WLS 10.3 with ADF Duncan Mills' blog entry about setting up WLS 10.3 for ADF in JDeveloper 11g (Boxer)

	Oracle JDeveloper documentation on OTN The official Oracle JDeveloper and ADF documentation consists of two books written for the ADF developer and the ADF Faces web developer. Improving our product documentation has been a mission since 10.1.3 and its over now. Though we easilly could call it a day, there is always room to improve, which is what the doc writers do with each iteration of the doc.
	Skin Selectors Skinning has been greatly improved in JDeveloper 11. Have a look at the skin selector documentation to leran about the options available to skin individual UI components.
	ADF Faces RC tag documentation ADF Faces RC provides a wealth of Ajax enabled JavaServer Faces components. This page, which is maintained by the development team itself, provides you best of breed information about how to use the individual tag elements.
