Mbean dependent jars?

Hi,

I am creating a weblogic custom authenticator and deploying the mean jar to the weblogic server\lib\mbeantypes as per the documentation.  The simple case where the authenticator is self-contained in one jar works fine, but what do I do in the more complex case where the authenticator has dependent jars?  I've tried unpacking the jars and assembling a single jar, but this doesn't work so well for libraries like Spring.  So where do I put the dependent jars? 

Regards,
