JSP debug

[Yesssss]

Hi to all, I'd like to know if is possible to debug a JSP without using
the System.out.print() istruction.

Thanks for answering, Luigi.

Yes.
I assume you also want to know how, right?

All jsp are compiled to servlets.

Either you have precompiled them or the servlet container does that for
you at runtime.
First they are checked for correctness according to the servlet spec
and if it is ok - creating the .java servlet file. Then that .java file
is compiled into an ordinary .class file.

When jsp are compiled you can choose to store the .java file as well as
the .class file.
The .java file can as any regular java file be debugged. Of course that
means that you
are not debugging/stepping the actual jsp file but the servlet that the
jsp represents.

That is one I way i know about.

Thank you very much for answering, but i have an other problem:

I'm running IIS and i have JSP files.

Now I would like to know how I can run JSPs on IIS and make a remote
debugging too.

I know it's weird but I have to do it in that way... it sucks for me!!!

Thank you again for your help, Luigi

Some tools, Oracle JDeveloper and (possibly) NetBeans will let you
singlestep through a JSP.
