Dear Christopher:

Thanks for visiting my humble thread. Your knowledge of Tomcat is always 
welcome (especially given that you've saved my E.asinus more than once). 
That said, . . .

Uh, "uname" is not a native command in whatever IBM is calling OS/400 
these days. If you were to type it on a native command line, you'd get 
an error message, "Command UNAME in library *LIBL not found." on your 
status line. (Note that the native file system is actually a DB2 
database, and object names are not case-sensitive.)

If you start a QShell session, which is a *nix-like shell environment 
where Java runs (but definitely not an actual Linux VM), and you type 
uname, you get "OS400."

And no, a Linux VM would not be easier. Short of setting up some sort of 
Linux LPAR on the box, I couldn't imagine how one would even do that. 
What I did to make it easier was to create a CL program (like a shell 
script for IBM Midrange boxes, except that CL programs are compiled) 
that looks for the most compatible JVM, sets parameters accordingly, 
then launches Tomcat. And another one that attempts to initiate a 
shutdown, waits for the job to go away, and if it fails to do so, abends it.
