Gah, I spent about an hour trying to find tutorials on how to do this, and this video is the first thing that finally just plainly shows how.  First video I found on YouTube!  Much appreciated!

Bro the double enter tip really help .Thanks a lot.

Thanks, man, just what I was looking for. I hate that in most courses they don't teach you how to do this, I mean, your IDE is supposed to handle that but I think its important to know what is actually doing the IDE for the jar file to run.

This one video answers what stackoverflow could not. Thank you.

Omg, that was really nice. Quick, simple and I get everything from this vid. Really, I read some tutorials and I get nowhere, till I saw this vid. Thx.

With most commands you can select every file with a certain extension by substituting the * symbol for the filename, like *.java,  *.class, or *.txt

Alex, Thank you very much. This video actually helped when Eclipse's Export has been failing!

thanks

I think they're automatically included if you create that JAR correctly. You might have to include a directory with the images in it, but I've never done something like that. There's a relevant question on stackoverflow:

Thank you, I've been looking for a tutorial like this forever :D

[Alexvreidy]

Yeah, pretty much. I imagine it can be used to declare other things as well, but apparently pointing to your main class is sufficient for creating most JAR files.

[vikramshinde]

Awesome man...short and sweet....tysm for the useful piece of info...

[Alexvreidy]

You need to set your classpath (the PATH environment variable) to include the JDK's "bin" directory. If you don't want to do that, just type out the entire path instead of javac: in my case, C:\Program MyProgram.java

[aaditshreyas]

mine is returning a command like this :

'jar' is not recognised as an internal or external command, operable program or batch file.

what to do next?

[keepaopenmind]

Thank you. That was very helpful. I had to create the manifest file, as you suggested. I thought java created the jar file with a manifest file already in it. But I guess not. At least it wouldn't run until I created the manifest.text file, put it in the same directory as the class file, and then ran jar -cfm jarfilename manifest.txt *.class.
Thanks again.
