1.1. Introduction into JDeveloper, ADF and JHeadstart 1.1.1. Oracle JDeveloper To get the most out of JHeadstart, it really helps to understand more about the underlying technologies. If you have used Oracle Designer in the past to generate Oracle Forms aplications you probably agree that good knowledge of Oracle Forms is rather helpful in generating more complex functionality. This also applies to JHeadstart, understanding how technologies like ADF Data Binding, ADF Faces and JSF work, is indispensable for generating complex applications that involve customizations to the default generator templates used by JHeadstart. This section provides the pointers to obtain this knowledge. Oracle JDeveloper is the Integrated Development Environment (IDE) that allows us to work productively. It provides a comprehensive set of integrated tools that support the complete development lifecycle, from source control, modeling, and coding through debugging, testing, profiling, and deploying. JDeveloper simplifies Java EE development by providing wizards, editors, visual design tools, and deployment tools to create high quality, standard Java EE components including applets, JavaBeans, Java Server Faces (JSF), servlets, and Enterprise JavaBeans (EJB). JDeveloper also provides a public Add-in API to extend and customize the development environment and seamlessly integrate it with external products. 1.1.2. Oracle Application Development Framework (ADF) Oracle JDeveloper on OTN. Overview, Online Demo’s, Tutorials, White Papers, How-to’s, Feature list, and more: http://www.oracle.com/technology/products/jdev Oracle ADF is an end-to-end J2EE framework, fully integrated with JDeveloper that simplifies development by providing out of the box infrastructure services and a visual and declarative development experience. Since it supports multiple technologies you have the choice to use the components that best fit your situation. Oracle ADF comes with extended design time facilities. By using simple drag-and-drop of the model components you can build page by page in a highly productive manner. For Java Server Faces a very useful page flow modeler is included where you can draw the logic of your controller structure. The business services can be developed with several types of wizards (based on UML models), and several types of editors. Altogether Oracle ADF provides a first class J2EE framework that couples high development productivity with the flexibility to choose the components that fit your situation best. 1 - 2 Getting Started JHeadstart Developer’s Guide
1.1.3. What is Oracle JHeadstart? Figure 1-1 Oracle ADF Architecture Oracle ADF on OTN. Overview, Online Demo’s, Tutorials, White Papers, Howto’s and more: http://www.oracle.com/technology/products/adf ADF Developers Guide for Forms/4GL Developers. Very comprehensive developer’s guide with guidelines, best practices, hints and tips on building applications using ADF. JHeadstart is a development toolkit that works on top of ADF, fully integrated with JDeveloper, which enables rapid component based development of Java EE applications. It provides you with 4GL-like productivity without jeopardizing the flexibility and openness of the Java EE architecture. JHeadstart consists of three main components: • JHeadstart Runtime Library The JHeadstart runtime contains reusable components that extend Oracle ADF. These reusable components implement Oracle ADF best practices that were developed during custom development projects of Oracle Consulting. • JHeadstart Application Generator (JAG) Apart from the runtime components, JHeadstart provides significant design-time support. The JHeadstart Application Generator (JAG) is a powerful generator that automates the development of the Controller (JSF config file) , View (ADF Faces pages), and Model components (ADF data controls and data bindings). The JAG is driven by XML meta-data that you create using JDeveloper (plug-in) wizards and JHeadstart property editors, providing you with a declarative, 4GL-like experience in building Java EE applications. To help you to get started with the meta data, JHeadstart generates a first cut of the meta data based on your ADF Business Components, which can be retrieved from a UML class model or database tables.
