In the IDE

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, arranged by object type. You can create new objects, read about new types of objects that you haven't yet created, and initiate actions from the objects' context menus.

You can optionally close the Application Overview window, since you will not be using it to create objects for this application.

When you complete the steps for creating a new application and project, the Projects panel in the Application Navigator should look like this:

The Fusion Web Application (ADF) template that you used for your web application partitions your application into two projects: Model and ViewController. Projects are displayed as the top level in the hierarchy in the Application Navigator.

You can collapse and expand any panel in the Application Navigator. You can increase the size of the open panel by dragging the splitter between the Application Navigator and Structure window. You can use the Navigator Display Options menu to group and sort items in the open panel.

For application operations, click Application Menu and select an option.

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 multi-tier 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.

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 these elements have not yet been saved; however, the application and project you created were saved automatically. A project node is bold when a file in the project is selected or open in an editor.
