The first time you run JDeveloper, there are a few special dialogs that appear. These dialogs help you to configure JDeveloper for the type of work you will be doing.
The first of these dialogs is the "Roles" dialog. JDeveloper has a number of different "roles" that can be used to specialize the features available. The default role which is, strangely enough the default, allows all technologies and functions to be available.
The Roles dialog has a dropdown listbox with the various roles available, and a checkbox which allows you to specify whether you want to see this dialog each time you start JDeveloper. I typically uncheck this box. You can change roles later from within the IDE.
Click "ok" on this dialog and you will proceed to the next dialog (after a few second wait). If you have installed a version of JDeveloper prior to this one, you will be asked if you wish to migrate your settings from the earlier version. If you do not wish to migrate settings simply press <alt+n> to select "no" and the dialog will close. Otherwise you can have JDeveloper display a list of previous installations from which to migrate.
The next dialog that will appear is the "Usage Tracking" dialog. This dialog asks if you want to allow anonymous information about how you use JDeveloper to be sent back to Oracle so we can tell which features are being used most frequently. This dialog consists of a checkbox and an ok button.
Finally, the IDE actually initializes and you are presented with the "Tip of the Day" dialog. It consists of the tip text, a checkbox that says whether you want to see this dialog each time you start JDeveloper, a next button to see the next tip. If you do not wish to see these dialogs each time you start JDeveloper tab to the "show tips at startup" checkbox and uncheck it. Then tab through the entire dialog and back to the checkbox then press <ctrl+f4> to close the dialog.
If you want to see the tip of the day each time you start JDeveloper simply press <ctrl+f4> to close the dialog.
Tada! You are now on the main JDeveloper window. Focus is in the structure pane, so press <ctrl+shift+a> to move focus to the application navigator, and you are ready to get to work.
