How to check if all *.jars in my CLASSPATH really exists? Automatic check (not manual) possible?

Assume I have a long, long CLASSPATH containing approx 20 (or more) *.jar archives.
Is there a way to AUTOMATICALLY check if all mentioned *.jar files really exist?

I could imagine a command (or even java class) which checks this from command line:

java check_cp &CLASSPATH%

or similar

I doubt it. This is because Java doesn't really care about the jarfiles
themselves, only the classes which they contain. It will only try opening them
whenever it needs to access a certain class.

So I think that the only way to be sure is manually listing the classpath, then
grabbing all file entries and finally start checking up if those exist.
