JBI or OSGI packaging

[Mathew, Reju]

Hi,
 
I am a newbe to the ServiceMix. When developing new applications (using
servicemix - camel) deployed in ServiceMIX 4, which is the preferred way
of packaging - JBI or OSGI ? Do not envisage registering at / using
(OSGI) Service Registry and either way packaged seems deployable into
the osgi container of servicemix (using osgi install) in the same way.
So then which way is recommended / forward looking approach ?
 
thanks,
Reju
