I am having an issue running a servlet in jetty on Ubuntu 13.04. The server is installed using apt-get and started using sudo service jetty start.
apt-get
sudo service jetty start
Joakim Erdfelt pointed the cause, in case anyone needs a snip of pom code, put this in pom file:
org.eclipse.jetty jetty-util 9.3.6.v20151106
