Hi shtegtari, In order to execute a jar from command line, you have to pass the "-jar" parameter like: # java -jar /opt/downloads/xwiki-enterprise-installer-generic-3.0-standard.jar If you do not pass the "-jar" parameter, java tries to launch the class named "/opt/downloads/xwiki-enterprise-installer-generic-3.0-standard.jar" which is obviously not found.
