How to make a Java program be opened by default with Java, on any computer

Question

When I send Java games I created to friends, the JAR file I send them often looks like a RAR file to them. This is because Windows on their computers thinks this file should be opened by WinRar.

They have JRE on their computers, but the default on Windows is that the file they recieve should be opened by WinRar.

The people I send my program can't be expected to guess, that what they need to do is specifically tell Windows to open the file with Java.

Is there a way to make it so that a JAR file I send to somebody, will be opened on his/her computer by default using the JRE?

Thanks a lot

Answer 1

You can consider adding a BATCH script. Something like java -jar YourJarName.jar

You will need two of them - for unix and windows:

Windows start.bat:

java -jar YourJarName.jar

Unix start.sh:

#!/bin/bash
java -jar YourJarName.jar

Answer 2

您可以使用Launch4J之类的工具将JAR文件包装为可执行文件。
