Out of environment space – Tomcat

I’m trying to get Apache TomCat up and running. I already have jigsaw running, for which I set environment variable classpath=
a whole lot of pathnames.

When I run tomcat.bat, I get plenty of “out of environment space” messages, a “bad command or filename” msg, and an error in a java class.

How can I get rid of the “out of environ space” message?

Cheers
