Java to jar, with mainClass (something's wrong)

Question

Hi. I know, there were some topics, about the java to jar issue, but I think this is different a bit...
so the question is: I'm trying to make a .jar from my jave file, and I've found a tutorial for it on the net (and as far as I remember, I've used this tutorial before, and it helped)
it says, I have to use this command:
"jar cmf mainClass.txt example.jar *.class"
I have a proper mainClass.txt, but when I try to run this command, I get this error message
"*.class: no such file or directory"
what am I doing wrong?
Thx for any help.

Hi there,
As per the documentation you are trying to:
jar - The basic command
c - Create a new jar file
m - With a manifest entry
f - With the specific archive name
mainClass.txt - Name of the manifest file
example.jar - Name of the jar file you are creating
*.class - Jar up all of the class files that exist in this directory
So basically you have no class files in hte directory you are running this command from.
Also you'll probably want to run the command like so:
jar cmf example.jar mainClass.txt *.class - You'd typically have the name of the manifest file 2nd
