Jetty is a servlet container like Tomcat. Currently, it is completely inapplicable as a Java EE 6 application server, since the main requirement for the servlet container in this stack is the Servlet 3.0 container.
Jetty 7, the latest stable release, is still on Servlet 2.5. At the moment, no one knows when Jetty 8, which will support Servlet 3.0, will be released, but experimental releases can already be downloaded. See http://www.eclipse.org/projects/project-plan.php?projectid=rt.jetty
Even when Jetty 8 is eventually available, you will of course need to add JSF2 (Mojarra), CDI (Weld) and JPA2 (Hibernate).
