Jetty supports JNDI, but by default it is disabled in a standard server. In order to enable JNDI in Jetty a few changes to the start.ini file in Jetty home directory must be made:

1) Add 'plus' and 'annotations' to OPTIONS, so that it looks something like this:

OPTIONS=Server,jsp,jmx,resources,websocket,ext,plus,annotations

2) Enable the plus configuration by adding the following line:

etc/jetty-plus.xml

at the end of the file next to other similar entries.

That's it, Jetty should now support JNDI.
