Newbie: Multiple instances of application in Tomcat

Hi!

Can Hibernate (v3+) be used in a Tomcat (v5+) environment, where multiple instances of the application are running in the same Virtual Machine? (different instances of the application are pointing to different databases.) Wouldn't the two instances share the same second level cache?

Thank you in advance!
