The J2EE Reference Implementation, version 1.2, includes a modified version of
Tomcat 3.0 as its servlet/JSP component.  The next version of the J2EE Reference
Implementation, version 1.3, will include Tomcat 4.0 as its servlet/JSP
component.
(Several other J2EE or similar environments also support Tomcat for their web
layer.)

The differences between Tomcat and the J2EE RI (or any other J2EE server) are
pretty easy to understand:  Tomcat supports servlets and JSP pages only.  J2EE
servers support many additional technologies (as well as servlets and JSP
pages), including Enterprise JavaBeans, security, transaction management, a JNDI
naming service for resource access, and many more.

For more details on what J2EE-compliant application server must provide, see the
J2EE Specification at <http://java.sun.com/j2ee>.
