J2EE has a large number of technologies beyond the servlet and JSP support
present in Tomcat, plus requirements on the container for configuring
resources such as JDBC data sources.
Tomcat 4 is a complete implementation of the servlet 2.3 and JSP 1.2
requirements, and supports a small subset of resource factories that are
upwardly compatible with J2EE programming standards, but it does NOT
contain any support for the extra technologies such as EJB.

You will need an EJB container in order to program EJBs. Two approaches
for you to look at:
* Get the J2EE 1.3 Reference Implementation from Sun
<http://java.sun.com/j2ee>. It embeds Tomcat 4 inside to provide
the servlet and JSP technologies, and also supports all the rest.
* Get an external EJB server that can integrate with Tomcat,
such as JBoss <http://www.jboss.org>. It connects with Tomcat
to provide the web layer, and itself provides EJB support.
