      OOo_HOME=/usr/bin
      SOFFICE_PATH=$OOo_HOME/soffice
      PIDFILE=/var/run/openoffice-server.pid
      
      
      set -e
      
      
      case "$1" in
      start)
      if [ -f $PIDFILE ]; then
      echo "OpenOffice headless server has already started."
      sleep 5
      exit
      fi
      echo "Starting OpenOffice headless server"
      $SOFFICE_PATH -headless -nologo -nofirststartwizard -accept="socket,host=127.0.0.1,port=8100;urp" & > /dev/null 2>&1
      touch $PIDFILE
      ;;
      stop)
      if [ -f $PIDFILE ]; then
      echo "Stopping OpenOffice headless server."
      killall -9 soffice && killall -9 soffice.bin
      rm -f $PIDFILE
      exit
      fi
      echo "Openoffice headless server is not running."
      exit
      ;;
      *)
      echo "Usage: $0 {start|stop}"
      exit 1
      esac
      exit 0
      --------------------------------------------------------------
5. Exit the nano editor and save the file you just did. Make the script executable and make it start automatically at boot
   $ sudo chmod 0755 /etc/init.d/openoffice.sh
   $ sudo update-rc.d openoffice.sh defaults
   $ sudo /etc/init.d/openoffice.sh start
   
   
6. Go to Settings->Customization->Aeroo Reports->Configure OpenOffice.org connection. Click Connect. It should display that connection was successful and PDF conversion is working.
