[jetty-users] War overlays in Jetty 9

[ccleve <ccleve.tech@xxxxxxxxx>]

I'm having a tough time figuring out how to use war overlays in Jetty 9. 
jetty-overlay.xml is not included in the M3 /etc directory, and the 
documentation at 
http://www.eclipse.org/jetty/documentation/current/configuring-overlay-deployer.html 
is confusing and maybe out of date.

I just want to have a common.war file that all of my webapps share. If a 
user goes to http://host/mywebapp/myfile.html and that file doesn't 
exist in /webapps/mywebapp, it should get pulled from common.war. 
Dynamic files like .jsps need to work as well.

I'd using embedded jetty.

(I'd also like to prevent each /mywebapp directory from having its own 
/WEB-INF, but that's a separate requirement.)

So how do I create a common war file and tell the container to use it?
