Hi All,

I've tried to publish my Java program by using "Clean and Build" in Netbeans. It's produced a .jar file - but when double clicked, it loads nothing.

I've tried loading it on the command line using:
java -jar "C:\Users\USERNAME\Desktop\program1\dist\MYPROGRAM.jar"

And the error:
Failed to load Main-Class mainfest attribute from:

I've been told to create a .txt file with the line:
MainClass : MainMenuUI.

But this doesn't seem to have any effect.

EDIT - I've managed to answer my own question and publish my program. Is there any way of converting it to a .jar as by having my program as a .jar file limits the amount of people able to use it. (IE - They must have a JRE installed?)

I am running Ubuntu linux. is that for me to make this application runnable by window users ? and by runnable, i mean, for them to be able to just click the icon and have the application start up. it won't work for me to tell everyone i distribute this to a long string of letters they need to type into CMD to start it up
