No module named com.sun.star.connection
No module named com.sun.star.beans

My Ubuntu 12.04 server is on bitnami amazon cloud server, I've installed it using OpenERP stack provided by bitnami.
I've tryed several solutions on Google like install different version of Openoffice or Libreoffice, modify PYTHONPATH, but it doesn't work.
Thank you for help!
