Actually, yes, I would like to use the Debian package.  I like
the ease of installing/upgrading/removing packages with apt-get.

While I was investigating the problem, I started to notice that
it 'magically went away' somehow... so I did the following test:

* Compile a class file and put it under WEB-INF/classes/
* restart tomcat
* check the URL -> i get the NoClassDefFound error (for HttpServlet)
  that i described earlier.

-> now I wait for about 10 to 20 minutes

* I restart tomcat
* I refresh the webpage in my browser... and now magically it

What I conclude from this, is that the servlet-api.jar is at the
right place, but somehow it takes a while for tomcat to notice

My only problem is that, taking into account the above behavior, I
have no clue where to look for the possible cause of this.

If somebody could point me in the right direction, it would be
very much appreciated.

Kind regards,
