Starting a Debugging Session
This page explains how to start debugging a standalone program or applet project. To begin, you must have a project that you compiled inside JDE with the -g option. If you don't have such a project, debugging is disabled.
To start debugging a project:
- Double-click a project in the Project Manager window to select the project you want to debug.
The source editor window automatically loads your program source files (if the sources are available).
- Set a breakpoint in your program.
- Click the Restart button

on the Edit/Debug toolbar.
The following actions occur:
- JDE begins debugging your project. If you set a breakpoint in your source code,the line with the breakpoint changes from red to green to indicate where program execution stopped. You can now set additional breakpoints.
- If your project is an applet, JDE launches the applet viewer. You execute the applet in the applet viewer using the Go button

on the Edit/Debug toolbar.
On Microsoft Windows 95 and Microsoft Windows NT, the applet viewer does not respond to window operations, such as repainting, when the applet is suspended at a breakpoint. To manipulate the viewer under these circumstances, do one of the following:
- Press Alt+Tab to bring the viewer to the front.
- Press Control+Escape to display the task list.
