Tom, thanks for your hint.

Ii unfortunately wouldn't help to solve my current problem, because 
JarFile either doesn't provide getChannel().

... But it would help to simplify my other problem from thread:
"How to get list of classes from a package" from 2009-02-16

Anyway, don't you think, there should be something like 
getResourceAsChannel() ?
