Hi Joe,

Thanks for the input.  To answer your question, I have not brought up Tomcat
on any other system.  I had planned on waiting till we get v5r1 before I start
learning it.  Maybe I'll think about finding a PC to load it on  Do you know of
a good email list PC related to get me over the hurdles?

Thank you,
