I just want a sample and simple jar file and run it.

Oracle's Tutorial works through an example in the Lesson: Packaging Programs in JAR Files (The Java™ Tutorials > Deployment) section.

The details (so you can understand and apply the simple example) are to be found, if needed, in the Jar guide.

I strongly recommend what pbrockway2 suggests here to you.

You want to do it the "monkey see, monkey do" way? Why are you ignoring Pbrockway2's tip and links? (reply #2)

kind regards,

actually i'm after the output checking of the script, i do not have to create the script, I have a scheduler wherein i will execute the java script, client gave me their java script and i want to test first a sample java if my scheduler can execute this kind of script. that's is why i'm looking for a very simple java script where in i can easily look also for the output for checking, for ex. a simple copy file. thanks! :)

Congratulations, you have put a .bat file in a .jar file; now what? .jar files are for compiled Java files and their resources. You could as well have put that .bat file in a .zip file ...

kind regards,

Reread this from my previous reply:

My previous response was motivated by a couple of things.

First, I really don't think anyone here is going to write your code for you. I won't, anyway. This isn't mean spiritedness, it's just I'm not paid to, it's not fun and doing so would not advance anybody's understanding. The last point is most important as I take growth in understanding as the reason why most folk are here. It's why I'm here, anyway.

So you are going to write your code. And the links were designed to help with that.

The second reason was because I know of no better source for explaining what an (executable?) jar file is. Your original post suggested it might be beneficial if you found out about the concepts involved. Your more recent post confirms that.

Generally I wouldn't have responded again: your silence on the content of my previous post being response enough. But your continual insistence on using this forum as a substitute for doing the work motivated me to reflect, as above, and offer a different reason why we're here and what the bandwidth's good for.

But good luck with your endeavour.

oh ok, thanks a lot. :)
