Are there ways to debug JSP files of openfire?

Hi there,
I’m editing my code openfire 4.7.0 and I’m wondering how can I debug the JSP files.

The Java files can debug and these are pretty working. But when I try in JSP files,
IntelliJ said “breakpoint does not belong to any class” bla-bla

If u know how can debug JSP files, Plz tell me what I to do.

I actually do not know. It sure would be handy to have that, but so far, I’ve not had issues so severe that I had to invest time in figuring out how to do this. If someone knows how to do this, I’d be interested to learn.

I just build the code and run it, then figure out what’s wrong. In the rare occasion that I do need to dig deeper, the build holds the generated java files that can be viewed in a text editor.

Thank you for answering me. Have a great day Guus!
