Using the Source Editor When Debugging

When the debugger stops, (for example, at a breakpoint after completing a step command, or when paused), the source file for the current class will open in the source editor and will be marked with the execution point .

If JDeveloper cannot locate the source file for the class while debugging, the Source Not Found dialog is displayed prompting you for the source file location.

You can use the source editor to debug in the following ways:

Setting Breakpoints

To set a breakpoint, click in the source editor's margin.
To remove a breakpoint, click in the source editor's margin.

Context Menu Items

The debugger adds several menu items to the source editor's context menu including:

Toggle Breakpoint (F5) - Sets or removes a breakpoint.
Run to Cursor - Lets you run to a specified location and execute the code until it reaches that location.
Set Next Statement - Lets you move the execution point to a specified location, without executing any code.
Watch (Ctrl+F5) - Lets you add an expression to the Watches Window.
Inspect - Lets you open up a floating Inspector window.

Tooltips

The debugger will show tooltips in the source editor if you hover the mouse over the name of a variable. The tooltip will show the current value of the variable. If you want a tooltip to display the value of a more complicated expression, select the expression in the source editor and hover the mouse over the selected text.
