i used http://www.openvpms.org/documentation/install-openoffice-headless-service-ubuntu
for run openoffice and libreoffice 3 at ubuntu start up
but
due to some PID change it dont work for liberoffice4
anybody know how can i run Libreoffice 4 at startup!?
UPDATE 1 : as its mentioned in the link I mean libreoffice - headless in ubuntu server so it dont have any UI.
