Re: [jruby-user] Missing files (or seemingly so)

Tim,

I'll check that out.  This is on an IBM i which is a bit different from 
any other mainline OS.   Anything that executes java is A-OK because the 
J9 JVM that IBM has is rock solid on this platform but if we are talking 
about any executable binaries, then things get interesting.  Most of 
what I run I run in an environment called PASE which is an AIX-like 
shell that can execute most binaries that can run in AIX.  Sometimes I 
have to compile to run in PASE (PPC64) so it will vary based on what the 
binary does. Because of those unknowns, sticking with a "pure" java 
install: Unzip, set path and classpath, and go,  is the way I deploy 
most applications in the java world.

But, I'll give it a whirl....
