Help: "jarsigner: unable to open jar file"

While signing my own jar files is a trivial process, why is it that 3'rd
part libraries I wish to distribute as their own jar files (to achieve
Java Web Start application segmentation) fail with a "jarsigner: unable
to open jar file" message?

The file in question is the jcommon-1.0.0-rc1 of
http://www.jfree.org/jcommon/

Thanks in advance,
Casper

It's because you're doing something wrong. If you want to know more,
you'll have to be more specific -- for example, by providing the
location of the JAR file and command line you use to invoke jarsigner.

Ahh indeed. It was not the tool itself, but rather a problem with
accessing the file (jcommon-1.0.0-rc1.jar) from an XP command prompt.
Renaming it to jcommon.jar did the trick.

Thanks,
