apache to tomcat connector
Posted by Joe Hanish <jo...@joeshouse.net>.
Hi, I'm fairly new with all this technology, but I've managed to get tomcat
(latest) and an application running... I was wondering if anyone had some
quick pointers on what to read to get it rigged up with apache... I've read
a few things, but the info seems scattered, and I'm not sure what I need.
Can anyone just point me to something to look at to help with this? Thanks
a bunch.
Joe
