Re: [jetty-user] Resource loading problems on x86_64 (Jetty 6)

Sorry, I should have followed this up to say that we found the source of
the problem: by default, jetty unpacks the WAR file to /tmp. We had a
cron job reaping old files from /tmp, and this was deleting the unpacked
web app and all our resources, thus causing the problem.

The fix is to follow
http://docs.codehaus.org/display/JETTY/Temporary+Directories to get the
web app unpacked to an alternative location outside /tmp.
