Subject RE: JK2 + multiple JVM + multiple virtual hosts
Date Thu, 09 Jan 2003 21:42:45 GMT

I think you can just use CATALINA_HOME and CATALINA_BASE. Based on your
post, it sounds like you have /usr/local/tomcat1, /usr/local/tomcat2, and
/usr/local/tomcat3 which is probably overkill.  Though my guess is it's not
worth the trouble at this point to reverse what you've done if it is all
working.

See item 4:

http://jakarta.apache.org/tomcat/tomcat-4.1-doc/RUNNING.txt

Thanks for posting your configuration, I'm sure it will help others out
there with the same environment.

John
