Subject Re: multiple jvm's? followup

Just wanted to share with everyone what I did, and pose a question.
My goal was to setup 2 separate environments, (one for test that had to be stable and one
for test where stability didn't matter).
There was no mention of this in the online FAQ, but I did find some info in the uguide.html.
Basically in the tomcat.conf, set up 2 mount points with different ports. Then create 2 server.xml
files, each defining their own contexts.
Then startup.bat -f <path to first server.xml file> and startup.bat -f <path to other
server.xml file>

This works very well.

My question is how to get these guys using different versions of the jdk? Currently they both
use the same tomcat.conf file. How would I do it if I wanted one mount to use 1.1.8 and the
other to use 1.2?
