The OpenOffice connection has been lost

Whenever I tried to restart alfresco on fedora 14, I used to get these errors in alfresco logs.

An initial OpenOffice connection could not be established. 
The OpenOffice connection was re-established.
The OpenOffice connection has been lost.
And the results was, not able get the preview of the documents uploaded in share.
So, here are steps which I carried out to get the issue resolved:

1.  In .../alfresco/tomcat/shared/classes/alfresco-global.properties replace the values as per your environment

          ### External executable locations ###

          ooo.enabled=true

          ooo.exe=.../openoffice.org3/program/soffice.bin

          img.root=.../alfresco/common

          img.dyn=${img.root}/lib

          img.exe=${img.root}/bin/convert

          swf.exe=/apps/alfresco/common/bin/pdf2swf\

     2. To run openoffice as daemon, create file openoffice.sh and copy the script given below.

         #!/bin/bash

         # openoffice.org headless server script

         # chkconfig: 2345 80 30

         # description: headless openoffice server script

         # processname: openoffice

         #

         OOo_HOME=/usr/bin

         SOFFICE_PATH=.../openoffice.org3/program/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

         *************

(Thanks for the script Vic Vijayakumar,  Federico Ch. & Tomasczik)
Save the file in /etc/init.d/openoffice.sh and give executable permission.

     3. Sartt the openoffice headless

         # /etc/init.d/openoffice.sh start

     4. Start Alfresco

Hope this works good for you too.
