Appendix A.3.4 Learning about jetty-env.xml
A jetty-env.xml file is an optional file that you can place in your webapp’s WEB-INF directory to configure JNDI resources specifically for that webapp.
The syntax of the file is the same as for the jetty-web.xml file.
At startup, Jetty automatically looks for a file of this name in the webapp’s WEB-INF directory, and set up the webapp’s naming environment so that naming references in the WEB-INF/web.xml file can be resolved from the information in the WEB-INF/jetty-env.xml file (along with any global naming resources defined in a jetty.xml startup file.
Example:
<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//
