The Zabbix Java Gateway Jar is currently installed in /usr/sbin. This is not the proper location, according to the jpackage guidelines. Much rather, it should go to /usr/share/java and the .jar extension should be left on. The configuration file should be given a less generic name than settings.sh and it should reside inside /etc.

Besides that and related to the ZBX-4800, I'd love to see an option to use the system-wide Java libraries, rather than the bundled ones.
