[jetty-users] configure.dtd downtime?
|
Hello,
what happens if this URL is not reachable for whatever reason?
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd";>
My Jetty 7.1.15 just hang for several minutes during startup and a threaddump indicated that the Xml-Parser waits for an
URLConnection.
Should/can I remove the DTD from the jetty-config files to be save on a production server?
regards,
Daniel
