Shrikant,
Yes, when you update your JomSocial status, it can be pushed automatically to your Facebook wall. If that's not working, there are usually a few easy reasons, and all are easy to fix.
Please let me know what version of JFBConnect and JomSocial you are using, and we should be able to fix you up quickly.
Also, please post from the account you subscribed to JFBConnect from. Priority support is for active subscribers only.
Thanks,
Alex
