My custom nuxeo platform don't use some services provided by deafult by nuxeo. for example (org.nuxeo.ecm.platform.convert.ooomanager.OOoManagerService) It starts the open office .Which is not need in my case

after search i can find that we can override a operation.(http://blogs.nuxeo.com/development/2013/05/extend-nuxeo-drive-1/)

I am not sure if its possible or disable a component (service) ?

Ho to deactivate or do not load not required nuxeo component (service) while server startup ?
