I'm not convinced that that is the problem at all, and I don't think that anyone would
want to delete conf/web.xml because it is not an example descriptor, it is the global
descriptor that is inherited by all other web-applations. It defines a long list of
default mime-types and other variables that I don't think programmers would want to
enter separately into each individual web-app descriptor (web.xml).
My best guess is that this sudden death-on-startup of Tomcat has to do with servlets
that have load-on-startup set to a value other than 0. For some reason, if I have
load-on-startup for my own servlet, Tomcat crashes as previously described. If I
commment that out, it starts up just fine, without removing conf/web.xml and even with
other servlets (notably those that come with Apache AXIS) having load-on-startup
specified. This leads me to believe that they implemented their servlets correcty and
I did not. However, I was under the impression that all you have to do is supply the
method init(). I have this method and init(ServletConfig) implemented and my servlet
still crashes tomcat on startup if it has load-on-startup specified.
If anyone has any ideas as to why this is the case, I would be very grateful.
Hopefully these details give further useful clues as to why some people have been
getting this behavior from Tomcat 4.1.12. Thanks.

-------------------------------------------------------------------
I just had a run in with the problem that other people
seem to be experiencing, and I think I have solved it.
Problem
-------
After a default installation of Tomcat 4.1.12, after
starting Tomcat, it immediatley shuts down before you
can see any backtrace in stdout (console window), and
there is nothing in /log.
Reason
------
Tomcat 4.1.12 default web.xml includes the examples
webapp even if you did not want it.
Evidence
--------
Using 'catalina debug'
C:\PROGRA~1\APACHE~1\TOMCAT~1.1\bin>catalina debug
Using CATALINA_BASE: ..
Using CATALINA_HOME: ..
Using CATALINA_TMPDIR: ..\temp
Using JAVA_HOME: C:\j2sdk1.4.1

Solution
--------
Delete the example webapp context from /conf/web.xml
Hope this helps!
