RE: TOMCAT_BASE and TOMCAT_HOME

There was a change in 6.0.21 (6.0.24 - released 2010-01-21) that now a Tomcat instance looks both into $CATALINA_BASE\lib and $CATALINA_HOME\lib for libraries. Ahh! This makes it clear. So, for 5.5 and early 6.0, if you wanted to add anything to these lib directories, and you didn't

Why would separate instances require their own jar files? Is it not possible to point two concurrently executing jvm's at the same set of jar files? It is entirely possible, of course. But you'll have some maintenance work to do if ever you wish to change the jars for _one_ Tomcat

Yes, but is there a technical, i.e. JVM, reason that two running instances of tomcat can't concurrently use the same shared libraries? None at all. Further, you can have both a $CATALINA_HOME/lib and a $CATALINA_BASE/lib with BASE always taking priority over HOME. Therefore, use HOME by

This means that for multiple instances to work, each Tomcat instance has to have its own set of these directories; they cannot be shared by two differently configured Tomcat JVM instances. The book is somewhat suspect, unless it explains the reasoning behind such a statement. JAR files
