Dude, It's kinda crazy. I was having the same problem. Your best bet is to use an absolute path from the file system, (not from the base %TOMCAT_HOME% directory or anything like that). Not only is it difficult to determine what the default path is from Tomcat, but I've also noticed that if I read a file from a certain location, let's say "/opt/ito/distrib/filename", "/opt/ito/distrib" becomes the new default path. So even if you could figure out what the default was to start with, it can change.
Using an absolute path seems to be the only way to be sure you find your file. This should also fix your problems with #3. I've read many files and executed many applications from the doGet() and init() methods. So if you are still having problems with this after the absolute pathing issue, let me know.
