Dear friends on this mailing list,
This is my first post here. My name is Stefano Locati, I'm from Italy
where I'm studying computer science at the university and I'm doing my
final work.
I'm trying to debug servlets using my ide, and I've read the thread on
this mailing list. From the post <The
"Debug-your-servlet-in-any-IDE"-tutorial> of Christof Baumgaertner
<[EMAIL PROTECTED]> dated back 10 Sep
1998 there is a simple stub to start the little webserver contained in
the package sun.servlet.http.*.
Since I'm using jswdk-1.0 I've noted that the package name has changed
to com.sun.web.server.* and also the api has changed. So the program
doesn't work with a simple import change. Unfortunately this api doesn't
seem to be documented, so I've used the etc/SimpleStartup.java example
and modified it. The initialization gave me a null pointer exception
that I could easily solve, but any connection to the server gives me
this error message (on the browser). Anyone can help me?
-The error message-
Error: 500
Internal Servlet Error:
