When you start application server as a service any console output writes to a log file in $OWARE_ROOT/jboss_<version number>/server/oware/log (for mediation server, see $OWARE_ROOT/jboss_<version number>/server/owaremed1/log). If you want to see the console output as it is generated, then run startappserver at a command line rather than having it start as a server.
