The value passed to System.exit(int) is passed to the OS. In Unix systems, 0 means success and anything else is generally not success. OpenVMS behaves differently, as already noted. If a process returns an error or fatal code to VMS, then by default the script running it will exit with an error. So changing the OS exit code can affect existing users. The point is that exit codes are not portable across OSes; the most one can hope for is sucess or failure indication. > > -- > Francis Galiegue > ONE2TEAM > Ingénieur système > Mob : +33 (0) 683 877 875 > Tel : +33 (0) 178 945 552 > f...@one2team.com > 40 avenue Raymond Poincaré > 75116 Paris > > --------------------------------------------------------------------- > To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org > For additional commands, e-mail: users-h...@tomcat.apache.org > > --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
