Arguments ignored in Java Jar

I'm running the following code on Ubuntu 10.10, using OpenJDK 1.6.0_18:

 package mypkg;
 public class MyTest {
   public static void main(fi开发者_运维知识库nal String[] args) {
     System.out.println(args.length + " argument(s)");
     for (final String arg : args) {
       System.out.println(arg);
     }
   }
 }

After compiling it into a Jar, I'm completely puzzled why executing the following command from the terminal returns 0 argument(s):

java -jar mytest.jar this is a test

This is my interpretation of the Java docs, stating:

java [ options ] -jar file.jar [ argument ... ]

I almost have the feeling that I'm entering a wrong command in the terminal. What gives?

Edit: the MANIFEST.MF contains:

Manifest-Version 1.0
Created-By: 1.6.0_18 (Sun Microsystems Inc.)
Main-Class: mypkg.Starter
Class-Path: .

Have a look at the contents of your META-INF/MANIFEST.MF file; make sure your Main-Class is using the correct class.

Your manifest specifies mkpkg.MyTest as the main class file, while the file you've actually posted has the name mypkg.MyTest.

Also, you specify a Classpath of "." in your manifest, which is superfluous at best, but probably leads to the problem you see (as you've probably got a directory named mkpkg in your local directory).

If you knew your main class you can do it without the -jar option.

java -classpath .:my_jar_file.jar; package.MainClass [arguments]

This is working for me on Debian Lenny.
