Help: jarsigner: unable to open jar file
06/02/2018 12:08
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

Thanks,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.
