Ldap implementation

Hi ,
i had coded an application which implements the LDAP and ssl functionality.for this i used the SUN provided provider and the packages like jcert.jar,jnet.jar,jsse.jar and etc..
now if i had to migrate the same onto IBM's site , i hear that it needs to use IBM related security features like ibbmjsse.jar and etc..
is it a compulsion that i need to edit the code to make it compatible with ibm java or there any other alternative..

any response is highly appreciated. its a bit urgent.

Regards
