Setting Breakpoints in Source Code
After adding the source code to your project, you can debug any Oracle ADF code for the current project in the same way as you have been doing for your own Java code. This means that you can press [Ctrl] + [-] (minus) to open a Go to Java Class dialog box, in which you can enter any class name in Oracle ADF. When you select the class and click OK, JDeveloper opens the source file automatically so you can set breakpoints as desired.
Hint: In the Go to Java Class dialog box, you can just type in the uppercase letters from a class name. For example, to find JUMethodIteratorDef, you can enter JUMI and the class is located.
