When you complete the steps for creating a new application and project, the Projects panel in the Application Navigator should look like this:
In JDeveloper, an application keeps track of the projects (collections of related files) you use while developing your application. Different projects might contain files representing different tiers of a multitier application, for instance, or different subsystems of a complex application. These files can reside in any directory and still be contained within a single project.
The Java Desktop Application (ADF) template you used for your application supports the MVC architecture by partitioning the application into two projects: Model and View. Projects are displayed as the top level in the hierarchy in the Application Navigator. In the example, you will use the Oracle ADF Business Components technology in the Model project, and the Oracle ADF Swing technologies in the View project. Each of the projects has appropriate technologies already included, defined by the application template you selected when you created the application.
In the Application Navigator you can collapse and expand any panel. You adjust the size of panels by dragging the splitter between two panels. To group and sort items in the Projects panel, use the Navigator Display Options dropdown menu. For application operations, you can click Application Menu and choose an option from the dropdown menu.
JDeveloper has the capability of recognizing many different file types, displaying each in its appropriate viewer or editor when you double-click the file in the Application Navigator. Closing an application or project closes all open editors or viewers for files in that application or project and unloads the files from memory.
Note: Nodes in italics in the Application Navigator mean that the elements have not yet been saved. A project node is bold when a file in the project is selected or open in an editor.
The Application Overview window opens by default in the editor window area when you create a new application. All objects that you create within JDeveloper appear in the Application Overview file summary pages, arranged by object type. You can create new files and artifacts, and view them filtered by status and project.
You can optionally close the window, since you will not be using it to create objects for this application.
