I did not think that I was /assuming/ anything.
The link provided below explains exactly where "Tomcat" is looking for classes and
libraries, and "." is not part of that (usually).
FYI: In Windows there is a patch available that can damage this path searching
defaults and
assumptions always bite you. It is always best to specifically set these
variables (JVM search paths
etc...) so there are no assumptions, and it's always better to specify a
particular location of a
library (using an environment variable works best here) if you don't set the
JVM/environment so a
random library doesn't get used by accident.
I'm sure everyone's heard of DLL Hell (or .so Hell)... assuming paths that may
not be correct in
100% of situations are the path to problems.

That's probably true.
Normally you need to
place those files in /tomcat but that assumes that /tomcat is your current
directory when you
startup. Essentially you need to ensure that you are starting tomcat from the
base directory that
also contains your native code, then everything will work fine.
But that is probably hogwash.
The JVM which runs Tomcat has a series of paths where it will look for classes and
libraries; to which Tomcat itself adds its own series of paths; to which the webapp
classloader adds its own. The library should be in one of those, depending what its
"scope" is.
See here for the real explanation:
