jar file

[Marcus Hoe]

Hi
I can't seem to run the jar file which i have created using 'jar cf myjar.jar *.class.
I exec the command 'java -jar myjar.jar'. But it just doesn't work. Can any1 help?

Hi,
There are two ways to do that.
1)You need specify the class name which contains the main
method.
java -jar myjar.jar mainclass
2)Use a manifest file when you jar you java files.
jar cvfm myjar.jar manifest.mf *.class
Hope this helps.
