We're using a 3rd-party Java security provider which is correctly installed for the JRE 8 on the system I work on. Now I want to use the jarsigner tool from the JDK 11 on my system to work with this 3rd-party Java security provider. How to tell jarsigner that it should execute using my installed JRE and not using the java.exe in the JDK folder?

Why do you think that


    jarsigner.exe

uses


    java.exe

? If you need to run


    jarsigner

version 8 you have to install JDK 8. If you just want to use the security provider's resources run


    jarsigner -providerClass [provider-class-name]

    jarsigner

is a separate executable which is part of JDK but not part of JRE. As far as I know, there is no way (and also no need ) to link


    jarsigner.exe

with a specific JRE. You can run it idependently. What exactly do you mean by configuration from my JRE 8 ? What is the exact problem that you are facing? – Würgspaß Nov 7, 2018 at 13:10 I've created a new issue for the exact problem: stackoverflow.com/questions/53188671/… Note: keytool from the JRE works, as the JRE is configured correctly (java.security file + files in lib/ext folder). keytool/jarsigner from JDK do not work correctly - because the configuration is missing from whatever kind of JRE they are using. – D.R. Nov 7, 2018 at 13:15 BTW: I'm pretty sure that jarsigner.exe is a simple wrapper executable which calls into a java application. – D.R. Nov 7, 2018 at 13:15
