I have no kind of idea. I'm the system administrator, so I can only provide informations about how I've installed jetty and deployed the application. I'm using the shipped init script, that reads from /etc/default/jetty. In that file I have: JETTY_HOME=/srv/apprun/jetty/current JETTY_BASE=/srv/appdata/jetty/base-xxx TMPDIR=/srv/appdata/jetty/temp-xxx JAVA_OPTIONS='-Xmx4096m' The webapp is deployed in base-xxx/webapps/root Inside WEB-INF/ there, there is a web.xml which doesn't contain any reference to the classes ResourceHandler,DefaultServlet you mention. (I am providing web.xml as attachement) Inside JETTY_BASE I have a classic start.ini file with the following content: $ cat start.ini | sed -e '/^#/ d' -e '/^$/ d' --module=http-forwarded --module=console-capture --module=http jetty.http.port=8100 --module=deploy jetty.deploy.extractWars=false About JETTY_HOME, jetty runtime is unpacked here, untouched. > > If you are using the DefaultServlet, check how it is configured - do > you have caching enabled?
