Just on this point of multiple Tomcat Instances, how does the JVM fit into all of this. ie does Tomcat1 use JVM1 and Tomcat2 use JVM2. Or does Tomcat1 & Tomcat2 use JVM1?
Also if you had one Tomcat Instances and 3 apps would they all share the one instance of Log4j and its static methods or would there be three instances of Log4j??
