Difficulty in adding own manifest file

[amit sharma]

I create a folder w in which i have a java class in package my.Wen i use
D:\>jar cf qwe.jar w
jar file successfully creataed
but when i add a manifest file which has content
Main-Class: my.Test

I also press enter after my.Test
Now when i execute it in cmd
D:\>jar cmf qwe.jar man w
i get this error
java.io.FileNotFoundException: qwe.jar (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:106)
at java.io.FileInputStream.<init>(FileInputStream.java:66)
at sun.tools.jar.Main.run(Main.java:122)
at sun.tools.jar.Main.main(Main.java:903)
I didn't understand this error
Thanks

The manifest file has to come before the jar file.
Try

jar cmf man qwe.jar w
