Questions tagged [executable-jar]

A special type of jar file which contains all non-standard libraries and definitions necessary to run an application on a JVM.

An executable java program which can be started manually by typing java -jar foo.jar. Some operating systems (including Windows, Solaris and some Linux distributions) provide means to run the jar just as any other executable on that system.

Executable JAR files are distinguished by a 'extra field' on the first file with a hexadecimal field code of 0xCAFE. They must also specify a main class in the manifest (Main-Class: fooPackage.BarClass) which will be used to start the application.

How can you package an executable jar with a portable JRE?

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?
