JNDI Lookup Incompatibility between wls 9.2 and wls 6.1

I'm trying to lookup bean deployed on weblogic 6.1 from my application which is
deployed on weblogic 9.2
I'm getting following naming exception:

    javax.naming.CommunicationException [[b]Root exception is

Apparently there is a version incompatibility issue.

So what is the fix for this error if I don't want to upgrade other system to wls
9.2?

Thanks,
