When you complete the steps for creating a new application and project, the Application Navigator should look like this, when the Projects and Application Resources panels are expanded:
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.
The Fusion Web Application template that you used for your application partitions your application into two projects, using default project names or the project names you entered. Projects are displayed as the top level in the hierarchy in the Application Navigator. In the application, you will use the Oracle ADF Business Components technology in the model project. You will not use the ViewController project, instead you will create another project later for the user interface or view layer files.
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.
The Checklist steps you through the building of a Fusion Web application, according to Oracle recommended best practices. It optionally walks you through the entire process of configuring and building your application, with links to specific dialogs and wizards. Each step is also designed to teach you about the architecture, tools and resulting files using a combination of links to step-by-step instructions, relevant sections of the Developer's Guides, and descriptions of what happens in the IDE as a consequence of doing the work in a step.
All files and artifacts that you create within JDeveloper appear in the file summary pages, organized 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.
