== Apache Tomcat a Java EE application server? == 

 At the beginning the article states: "...or deploy on third-party Java EE application servers such as JBoss, Apache Tomcat...". AFAIK Apache Tomcat is not a J2EE Application server, but a servlet container (Geronimo "is" an app server...), so I'm not sure if the statement is correct, or if it's been redacted in a confuse way...
