This is a screenshot showing the Oracle JDeveloper as it appears when you first open it, prior to performing any configuration steps. It is divided into several panels, as follows:
On the upper left is a panel that has two tabs associated with it. One tab is labeled Applications and the other is labeled Connections. The Application Navigator tab is selected and a single entry appears in the panel, Applications.
On the lower left is a panel with one tab associated with it. It is labeled Structure.
In the middle of the display is a panel labeled Start Page. On this panel, there are several links that enable you to access help topics.
On the far right is a tabbed panel labeled Components. This panel is empty.
