Hi, Thanks I got the problem solved as per your suggestion.
However I could make it work with two bundles as per Toni's hint I included the jar in to the bundle one which was registering the service, this bundle exported the interface A. In the second bundle I just imported the interface A and retrieved the object and cast to A successfully. Thanks for your help and time.

You should make it into a third bundle and use Import-Package to depend on the interface. When a class is defined independently by two or more classloaders, the resulting classes are considered by the JVM to be different, even if they have exactly the same name and are defined from the same bytes on disk. Therefore you cannot cast an instance of one type into a field of the other.
