[xwiki-users] What version of Jetty am I running?

Greets, This page warns about Jetty 7 and 8: https://wiki.eclipse.org/Jetty/Howto/Configure_SSL I googled how to determine, and found the answer: java -jar start.jar --version However, on my installation, that fails, saying: Jetty Server Classpath: ----------------------- No classpath entries and/or version information available show. Any suggestions? Thank you! Doug The information contained in this transmission may contain West Marine proprietary, confidential and/or privileged information.
