explicitly make one bundle aware of other ?

[ramesh chandra]

I have wrapped an external library ( Cassandra - Hector Client ) as a 
bundle , but I am constantly getting a ClassNotFoundException. So , I 
tried passing the missing (Thrift Library) after wrapping as a bundle, 
but it does not help either.

Is there any other way I can explicitly make one bundle aware of other ?
Just in case if anyone has see it , this is the error

Caused by: java.lang.ClassNotFoundException:
