I am trying to create dummy jar file based on existing jar file; using java.util.Jar package classes like JarFile, JarOutputStream, Manifest class objects.
What I am tryig to do is
I have A.jar file
read A.jar; JarFile
get its manifest object with JarFile.getManifest()
If i specify this manifest in
Get ZipException -> Duplicate META-INF\META-INF.MF entry
What is the best way to achieve creating copy of one jar to another with slight change to manifest file.
Help is Appreciated

Easiest done from the command line, I would think. There should be something in the
; there is a section about modifying the manifest file.
