Multiple JVMS invite big problems..annotation and or Generic classes developed under JVM6 won't backport to 5 If on the other hand you are able to use common JVM and common TC you can bulletproof your webapps with Clustering http://tomcat.apache.org/tomcat-5.5-doc/cluster-howto.html This would ensure all webapps would be replicated in a TC Cluster If you are designing 2 or more webapps will never interact or use common libraries and talk to completely separate DBs then segregate the more distinct webapps to 2 separate TC clusters
