is there any pure-java or standalone deployable implementation of jarsigner? -

-

i've seen lot of questions here asking how deploy app jarsigner without full jdk. people ask how programatically jarsigner tasks.

i wondering if there pure-java implementation of jarsigner or standalone , alternate implementation of it, easier deploy apps.

(of course, know force user install full jdk in installation process or require installed jdk)

so question if there such thing alternate jarsigner.

if soul explain why jarsigner must native (because java can decompiled?), plus :-)

the executable part of jarsigner tool thin wrapper on pure java implementation. in fact it's same wrapper used java, javac, javap, etc.

the real problem have class files used jarsigner in tools.jar, isn't present in jre.
