Got it, Finaly I can see others 
.
It was a mistake from my side actually there were two jitsi.jar plugin files in the plugin folder which was creating a confusion for the engine and more over the linux geeks can get the logs from /var/log/openfire/error.log this log helped me alot. Use pipe for getting them out as they are too lengthy.........
Thank's Dele for the support and I'm love'n it
