1- Oracle JDeveloper 10g Quick Tour
Oracle JDeveloper is an Integrated Development Environment (IDE) which facilitates the design, development, debugging, and deployment of Java-based e-business applications. JDev10g handles multiple languages such as Java (J2EE, J2SE, J2ME), XML, SQL and PL/SQL.
Oracle renamed J2EE Framework to its own Oracle ADF (Application Development Framework). The code is transferable so you are not locked into Oracle ADF. Within this framework, you can build the Business Services, the User Interface, and test and profile the application.
With Oracle ADF and Oracle JDeveloper, you can develop User Interfaces for web applications, rich client applications or wireless applications.
In the Connections Navigator, you can use drag-and-drop functionality to add tables. Business Logic can be applied such as validation rules to ensure the data integrity.
Oracle JDeveloper can be customized to user needs. In creating new applications, you have the choice to use existing application templates or use your own.
Oracle JDeveloper has its own J2EE Application Server to quickly test applications thus reducing time. The Event Profiler is activated by clicking on Run, and presents any errors.
The profiler also provides a log of events which allows for check for quality and performance.
Using JDeveloper, the developer can work with XML Schemas and documents. With the XML Schema editor, you can interact using the Structure window, Component Palette, and Property Inspector. The XML editor has many productivity features.
2- Oracle ADF Quick Tour
Oracle JDeveloper 10g includes the complete J2EE Framework in Oracle ADF. The developer creates an application workspace in which you can specify the technology used in the application. You can drag-and-drop Database tables onto a UML diagram to create objects. There is a wizard to create default data model components. Oracle JDeveloper 10g offers WYSIWYG (what you see is what you get) editors to visually and declaratively design the user interface; views include HTML, JSP, ADF UIX, and Swing/ADF Client. The Data Control Palette displays all of the previously created Business Services.
3- Getting to know the IDE
Upon opening JDeveloper, you will notice three windows. The large window is referred to the Visual Editor or Code Editor. Next is the Application Navigator and last is the Structure window. You create a workspace by selecting Applications, File and New and naming a unique Project Name. The Application Navigator displays all of your workspaces and projects. Two new windows are now open; the Component Palette and the Property Inspector. As you design, you can see the Design View and also access the Source. Any changes to either window, will be immediately updated on the other window. After you save the page, you can instantly Run the page to view how it will appear in the browser, no connection to another server needed. However, you can use the Connections Navigator to connect to other devices such as a database connection.
