Can I call the class files that are in the jar library located in another jar file?

Question

I am trying to access class files packaged as a library, but unfortunately jar libraries need to be packaged into another jar file.

As an example, let's say that I have a.jar that contains some class libraries. I can call (import) classes in a jar file from my external Java application. Now I need to put this a.jar in another jar, say b.jar, and you need to access (import) the classes in a.jar from outside b.jar.

This is not what I want to do :)
