Unfortunately, I've got a feeling no one here can help you. I'd never heard of Gridway before, and when I went to check it out, I couldn't see how it fits into
Tomcat (if it does). From what I was able to glean, Gridway is a system for multi-system parallel computing more or less like Beowulf. But I didn't see where it actually fitted into webservers in general or Tomcat in particular.
The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.
You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.
