[jbosscache-users] Issue with JBC on Tomcat 5.5

[Brian Stansberry]

You can't integrate JBoss Cache with Tomcat's clustering. It's the 
logical equivalent to trying to get your mail client to act as your web 
browser -- sure at a real low level they both may use the same 
networking primitives, but that doesn't mean a mail client was written 
to act as a web browser.
