Hi Matt,

Double-clicking doesn't work here because the Finder tries to launches the JAR without a terminal attached, so System.in is unavailable and System.out goes to the console.log.

I think the easiest way to get what you want is to write a wrapper script, like you mentioned. Like if you're program is called myApp.jar and needs arguments arg1 and arg2, you can create a simple shell script like the following:

#! /bin/sh

java -jar /path/to/jarfile/myApp.jar arg1 arg2;

Make sure the file has its executable permission bit set.

The only caveat is that the Finder on your users system might not be associating shell scripts with the Terminal application, so your users would have to click "Get Info" for the file in the Finder and specify Terminal in the Open With: section.

Then, double-clicking the script will open up a Terminal window and execute your JAR.

Hope that helps,

Adam Ohren

GUI is too much work for this project. What would be the best way to write a "wrapper"? Please inform the uninformed :).

Your information and ideas were very helpful. Thank you.

Thanks,
