One clarification and a solution...

completely false

It is actually (partially) unpacked to 
CATALINA_HOME/work/Standalone/ .  I say "partially" because 
only contents of the WEB-INF/classes and WEB-INF/lib directory are 
extracted to said place.

This one is easy.  Never ever use File IO unless there is no other way to 
do what you need.  I this case, you can use 

See the javadoc for ServletContext for other ways to do this as well.
