I've just finished getting JIRA & Confluence up and running Tomcat on Ubuntu Server when I noticed on the web there were installation instructions for JIRA/Confluence on JBoss.
I am unfamiliar with JEE applications servers, having spent most of my time with simpler servlet containers.
However, assuming that JIRA does not make use of EJB's, why would one deploy it to JBoss? What does JBoss provide in this instance that Tomcat doesn't?
