Which bundle is it?
This is exactly the role of the getMyFactory method: to retrieve
information from the configuration by the bundle.
If you designed the bundle yourself and need more information that what is
in MyFactory, then either extend MyFactory to contain the desired
information, or add extra method next to getMyFactory in order to retrieve
the information you want (and the bundle will exploit this method, like it
does currently with getMyFactory) to retrieve the information in its run
method.
