Java EE (Java Enterprise Edition) General Discussion

Hi all!

I'm receiving a mysterious error when I try to run my web ap. "Wrapper cannot find servlet class com.ruffalocody.report.ReportServlet or a class it depends on"

I'm running it on JBoss 3.2.7, and I have another web ap, made almost identical to this one which does not display the same error/exception.

If anyone could give me advice on what I should do to fix this, I'd very much appreciate it. :)

Full exception message:
