如何使用便携式 JRE 执行 package 可执行 jar？

Question

I want to be able to distribute by executable JAR without having to make the user upgrade to the latest version of the JRE. How can I package a JRE into the JAR so that they can run the jar with no JRE installed on their system?

Answer 1

Put Java Portable in a sub-directory and launch your jar using a batch/bash script or Launch4j .

Answer 2

As you need a jre to execute a jar, I'm afraid this is not possible.

I have once used izpack together with launch4j to make a Windows EXE that would install a jre with my application.
