Thank you all!!! I did get it working (although as specified performance isn't where it should be.) I had to modify the jvm params for ant, tomcat, and jvm itself in a .sh script neatly placed in /etc/profile.d/
It's a virtual server on Godaddy and their technical turned into a sales call. They want me to upgrade to a full dedicated server... Which I'll do once I have proof of concept. I still need to work on getting httpd's config correct with regards to reverse proxy so my "clients" can go to order.domainname.com and get to the ecommerce front end. I'm only going to be running the ecommerce side, with some access to the backend to look at invoices. This will be a small group (not just anyone can go to the site and buy things (buying group)) So I'm hoping I can use the shared server for a year and get things just how i want them and take back up and migrate it to a full dedicated server. Godaddy wasn't about to modfy their virtuoso settings ither..... jerks! Thanks for all the help! I'm sure I'll be in touch about the proxy stuff in a short time!! Thanks again!
