Hello,

I tried to make an executable jar (a jar file that contains a main method, and once a user clicks on it from WinXP, it launches)...

The following code compiles correctly, but when I click on the jar file, nothing happens... Sorry if this post was supposed to be in a different forum other than the one for ant.

Many, many thanks!

All the best,

That looks correct. If I remember correctly, though, the file needs to have *two empty lines at the end* (that is, after Main-Class entry). You should check for that...
