My advice would be to focus on servlets deployed into an embedded Jetty instance within your server, and that's about it!

The other parts, like Session and Entity EJBs, JMS, Java Server Pages, SOAP, SAR and WAR packaging formats, JNDI etc. etc., have long ago been supplanted by much better technologies.

and JDBC too.

Why servlets instead of Jetty handlers?

JDBC definitely. I didn't mention it because I didn't think of it as part of the Java EE spec (JDBC preceded Java EE if I'm not mistaken).

As far as Jetty handlers, they might be a good alternative to servlets. I admit I'm not familiar with the details.
