ADF Architecture TV Do you want to learn the "big picture" of ADF development? Interested in design, architecture, development & deployment best practices and more? Then subscribe to the ADF Architecture TV channel where over 100 episodes delivered weekly by key Oracle ADF staff will discuss what you need to know to build a successful ADF application.
ADF Architecture Square When developing with a new technology, one of the challenges for technical staff is to both learn the features of the technology and how to implement them, and also consider the broader concepts of design, engineering and architecture. Many an IT project has come undone because IT staff have been focused on the nitty gritty details of writing software, rather than looking at the "bigger picture" of how it will all go together.

The Oracle ADF Architecture Square is designed to address this issue by focusing on architectural issues and developer guidelines for writing ADF software solutions. The goal, to give ADF developers an understanding of the decisions you need to build a successful ADF application, potential architectural blueprints to choose from when putting the ADF application together, and potential best practices to take back to your development team.

March/April 2015 -- Design Responsively

User interfaces (UIs) in smartphones and tablets are constrained by the device display size, lack of a physical keyboard, and use of finger gestures instead of mouse pointers. For these reasons, native mobile UIs are usually designed more simply and cleanly, and with more visuals, than equivalent desktop UIs. Mobile UIs tend to focus more on the display of information that is derived from data than on the data itself—the opposite of what most desktop UIs provide.

With the release of Oracle JDeveloper 12.1.3, Oracle Alta UI is now available. Oracle Alta UI is a design system and set of guidelines that promote a mobile-first design for Oracle Application Development Framework (Oracle ADF) web applications. Oracle Alta UI helps you build simpler UIs that enable application users to scan information quickly and perform work actions more easily.

This column provides an overview of Oracle Alta UI for the Oracle ADF Faces feature of Oracle ADF and gives you hands-on experience with building Oracle Alta UI–designed UIs with Oracle ADF.

November/December 2014 -- Thanks for Sharing

This article steps you through one way to perform a common developer task in Oracle Mobile Application Framework: sharing information among Application Mobile XML (AMX) features.

A feature in Oracle Mobile Application Framework is a unit of work—a single piece of application functionality that users can access from the mobile application springboard. An example of a feature is a product catalog in which users can query and select items to buy. AMX is one of three technologies that you can use to develop features in Oracle Mobile Application Framework.

Oracle Mobile Application Framework mobile applications can be developed in Oracle JDeveloper with the Oracle Mobile Application Framework extension, or in Eclipse with Oracle Enterprise Pack for Eclipse. In this article’s hands-on exercise, you’ll use Oracle JDeveloper and Oracle Mobile Application Framework to implement a customers feature that shares information about the selected customer with an orders feature.

July/August 2014 -- Region Extreme - Multi Task Flow Binding

Oracle Application Development Framework (Oracle ADF) regions display the contents of bounded task flows in designated areas on a page. Each region uses a special binding configuration—the task flow binding—in the Executables section of the parent page’s PageDef.xml file to populate the region content with data from the Oracle ADF binding layer.

In use cases such as analytic dashboards, the contents of an unknown number of task flows must be displayed as regions at runtime. However, Oracle ADF regions cannot be created at runtime. Multi-task-flow binding in Oracle JDeveloper 11g Release 2 and Oracle JDeveloper 12c addresses this limitation. Using a hands-on exercise, this article shows developers how to use multi-task-flow binding in Oracle ADF applications. Parts of the sample application have been prebuilt to give you a head start. In addition to performing the hands-on steps, you can learn more by examining the source files.

March/April 2014 -- JDeveloper 12c : REST for Everyone

Addressing the popularity of RESTful web services in application development, the new Oracle JDeveloper 12c integrated development environment (IDE) provides declarative support for building and consuming Representational State Transfer (REST) services in Java.

In addition, the new Oracle Application Development Framework (Oracle ADF) release includes a new data control for REST services that are to be used as business services for Oracle ADF web applications.

This article provides an overview of REST service development in Oracle JDeveloper 12c and, in its hands-on instructions, steps you through building and consuming a database-bound REST service in Oracle ADF.

November/December 2013 -- Mobile: The Next Big Wave

In his article “The Latest Infographics: Mobile Business Statistics for 2012,” Mark Fidelman, a contributing writer to the Forbes website, presents several interesting facts and statistics about the current and predicted future usage of mobile devices. A clear trend in this article is that business is “going” mobile and that in only a few years, the number of mobile devices will significantly outnumber that of wired devices and PCs used at work and at home. One message to extrapolate from this is that mobile application development is the next big wave in enterprise application development.

For enterprise application developers, a promising strategy for conquering the “go mobile” challenge is to embark on a hybrid mobile development approach that replaces the burden of device-specific native programming with a consistent development model that uses standard technologies such as HTML, CSS, JavaScript, and Java and can be run across multiple platforms.

This article introduces Oracle ADF Mobile and presents a hands-on mobile development and deployment exercise.

July/August 2013 -- Build Your Own

Declarative components in Oracle Application Development Framework (Oracle ADF) enable application developers to build custom JavaServer Faces (JSF) components from existing Oracle ADF Faces components (Oracle ADF Faces is a feature of Oracle ADF) and deploy them as reusable Oracle ADF libraries. Developers who want extra functionality with existing Oracle ADF Faces components or who are building a composite component such as an address field can use the declarative component feature to ensure layout consistency as they reuse components throughout Oracle ADF applications.

This article provides an overview of declarative components in Oracle ADF and provides a hands-on guide that walks through the declarative build process.

May/June 2013 -- Calling Home

One of the core architecture patterns in Oracle Application Development Framework (Oracle ADF) that promotes modular software design is the ability to expose bounded task flows in regions on a page. For a region to make callbacks to the owning page or view at runtime, developers typically use one of the following techniques:

  • Contextual events, the messaging channel of the Oracle ADF binding layer, which enables Oracle ADF regions to establish bidirectional communication with other regions as well as the owning page or view.
  • The task flow parent action activity, which can be used to invoke a navigation case on a parent page or view. It’s a declarative option, however, that allows only navigation.
  • Bean reference, a technique in which a managed bean of the parent page task flow is passed as reference to a bounded task flow exposed in a region. The bounded task flow uses this reference to invoke a method on the managed bean, thus calling back into the parent task flow.

Using contextual events, covered in two previous Oracle Magazine articles (see “Implement Contextual Events” and “Master and Commander”), is the most powerful technique for page-to-region and region-to-region interaction, and it also enables communication with nested regions. However, setting up contextual events is complex, and many developers balk at the unnecessary overhead for simple region communication use cases.

The bean reference technique explained in this article is easy to implement and well suited for many region communication use cases, making it an important part of the everyday toolbox of an Oracle ADF developer.

March/ April 2013 -- Catch Me If You Can

Java EE applications such as those you build with Oracle Application Development Framework (Oracle ADF) are based on a layered architecture following the model-view-controller paradigm. In such a layered architecture, each layer can become the origin of an application error that requires handling. As a consequence, error handling should be designed and implemented in all application layers.

Error handling is a large knowledge area, and complete coverage of the topic exceeds the Oracle Magazine article format. To fit the available format, this article covers an overview of error handling in Oracle ADF, followed by hands-on instructions on how to implement custom error handlers on the Oracle ADF Controller layer.

November/ December 2012 -- Master And Commander

An Oracle Application Development Framework (Oracle ADF) region is an aspect of the Oracle ADF Controller that executes bounded task flows in defined layout areas within a view, page, or page fragment, without forcing a refresh of the entire view. Think portlets and you have the right idea.

One common Oracle ADF Region use case that frequently appears on the Oracle Technology Network Oracle JDeveloper forum is a global toolbar or menu bar within a parent view. The goal is to have the global toolbar perform actions, such as data iteration, create/update/delete operations, or context-sensitive help display, on the view displayed in a separate region.

This article will show how to implement this use case by borrowing the idea of the command pattern from object-oriented programming. A command pattern implementation, deployed as an Oracle ADF library, is provided for you to use within your custom development projects.

September / October 2012 -- Consume Early / Consume Often

How to service-enable Oracle ADF Business Components application modules for consumption by SOA and Web services clients

Forward-looking enterprises build applications on a distributed architecture that transparently brings together Web, SOA, collaboration, content, and social networking services for user access from multiple device types (mobile, laptop, and so on).

In my last column (“Service, Please!,” Oracle Magazine, July/August 2012), I showed you how to consume and integrate remote services in an Oracle ADF Business Components application. In this column, I will show you how to expose Oracle ADF Business Components application modules as services for remote use with the primary consumers of such services: Java EE service clients, SOA components, and remote and local Oracle ADF Business Components application modules.

July / August 2012 -- Service Please!

Besides being used in SOA, Web services are a common access pattern in Web application development for remote data queries, application integration, and application departmentalization. Rather than enabling developers to directly access database tables owned by other lines of business, companies can expose the services interface to ensure data integrity and consistent application of business logic on the source data.

In this column, you will learn about the Web services integration options available for Oracle Application Development Framework (Oracle ADF) applications. Stepping through a sample application, you’ll learn how to embed calls from Oracle ADF’s Business Components models into Web services for create, read, update, and delete (CRUD) operations.

May / June 2012 -- Personalized Dashboards

Many enterprise applications being built today require flexible, dashboard-style presentation of visual data—bar charts, graphs, and the like—showing various levels of information at a glance. Flexibility these days also assumes a certain amount of personalization. The panelDashboard component of the Oracle Application Development Framework (Oracle ADF) Faces feature is a JavaServer Faces (JSF) layout container that Oracle ADF developers can use to implement such information dashboards.

This column will teach you how to change the Oracle ADF Faces panelDashboard component default layout behavior so that users can reorganize information areas according to their needs. You’ll also learn how to persist the user’s changes to the UI beyond the current session by configuring Oracle Fusion Middleware’s Oracle Metadata Services (MDS) feature in conjunction with the Oracle ADF Security feature so that the user’s personalized UI is displayed whenever that person logs in. (Note: hands-on requires JDeveloper for MDS to work properly)

March / April 2012 -- A Template With Behavior

This column provides an overview of the Dynamic Tabs UI Shell template and illustrates its key concepts through a sample application. Although the sample application doesn’t implement all of the template’s public APIs, it gives you a starting point for exploring how and when to use it.

January / February 2012 -- Security for Everyone

Protect your Oracle ADF applications from unauthorized access using Oracle ADF Security. Get an overview, introduction and running sample of ADF Security in Oracle JDeveloper

November / December 2011 -- Put On A Friendly Faces

Build a custom look and feel for your Oracle ADF Faces applications using the new ADF Skin Editor in Oracle JDeveloper 11g R2. Learn about the new skin editor, skinning strategies and work flow. Download Summit ADF with a red look and feel

September / October 2011 -- All Aboard

Build train models for navigation in bounded task flows. This article shares some hints and tips for programmatic train navigation and customization. The bounded task flow train is a powerful feature that gains even more power if you understand the model behind.

July / August 2011 -- Advanced List Interaction

Use model-driven LOVs in Oracle ADF to implement smart lists with autosuggest behavior. Model driven ADF Business Components list of values explained by example.

May / June 2011 - Implement Contextual Events

Use Oracle Application Development Framework’s Contextual Events feature for inter-ADF Region communication. To many developers, contextual events is a secret treasure that they have problems to fully understand. This sample explains step-by-step how to use contextual events with ADF Regions
