Oracle has released its Application Development Framework (ADF) Essentials that claims to enable the global developer community to leverage the core capabilities of Oracle Application Development Framework free of cost.

The ADF Essentials deploys on GlassFish Server Open Source Edition, giving developers the ability to adopt and extend Oracle ADF functionality to new environments.

Oracle ADF is an end-to-end Java Platform, Enterprise Edition (Java EE) framework that simplifies application development by providing infrastructure services and a visual and declarative development experience.

It also claimed to provide a simple way to develop enterprise applications with core capabilities and can be downloaded through Oracle Technology Network (OTN).

The Oracle ADF Essentials includes: ADF Faces, ADF Controller, ADF Binding and ADF Business Components.

ADF Faces is a set of Web User Interface (UI) components based on JavaServer Faces (JSF) that simplifies the creation of Web UIs, including interactive data visualisation.

ADF Controller helps build reusable process flows and provides the ability to create dynamic regions with changing content in Web pages.

The ADF Binding provides a simplified approach to connecting user interfaces to various business services through an XML-based, meta-data abstraction layer.

Oracle ADF Business Components simplifies developing business services against relational databases by providing declaratively-configured, reusable components that implement common design patterns.

The new release includes the core features of Oracle ADF, except declarative customisation, granular security layer, integration with Oracle SOA Suite and Oracle ADF Mobile.

Oracle Application Development Tools vice president Chris Tonas said ADF is a strategic framework used to build Oracle Fusion Applications.

"With Oracle ADF Essentials we’ve combined key tooling from Oracle ADF, Oracle JDeveloper and Oracle Enterprise Pack for Eclipse in a free offering that should be a great way for many of our customers and partners to jump start their development efforts," Tonas said.
