Q: URL of Class?

[Mark]

Is ClassLoader.getSystemResource the only way that I can determine
where in the filesystem a particular Class was loaded from (assuming
classes are coming from the filesystem)? In my application I have a
need to know where a class came from.

The reason I ask is that I have a specialized classloader and wish to
know whether I have to override getSystemResource. Or is there another
way I can determine the URL given an instance of Class?

Many thanks in advance for any useful answers!

Hold your breath:

getClass().getProtectionDomain().getCodeSource().getLocation()
