Answer 1

The Eclipse debugger needs the source code of what's executing on the server. Typically, you can download the source online as a jar or zip, then save it somewhere on your machine. Then click "Change Attached Source" and point to the downloaded source jar or directory where the zip was extracted. ~NCM
