Ich möchte gern aus einem JavaProgramm mehrer Dateien in einem Jar Archiev packen inclusive Manifest

Kann mir jemand erklären wie ich das realisieren kann und wie ich das Manifest manibulieren kann?
 
Hallo!

Schau mal hier:
Code: 
 /**
  * 
  */
 package de.tutorials;
 
 import java.io.FileOutputStream;
 import java.io.InputStream;
 import java.util.jar.Attributes;
 import java.util.jar.JarOutputStream;
 import java.util.jar.Manifest;
 import java.util.zip.ZipEntry;
 
 /**
  * @author Tom
  * 
  */
 public class JarFileCreationExample {
 
 	/**
 	 * @param args
 	 */
 	public static void main(String[] args) throws Exception {
 		Manifest manifest = new Manifest();
 		Attributes mainAttributes = manifest.getMainAttributes();
 		mainAttributes.put(new Attributes.Name("main-class"), HelloWorld.class
 				.getName());
 
 		JarOutputStream jarOutputStream = new JarOutputStream(
 				new FileOutputStream("c:/tutorials.jar"), manifest);
 		ZipEntry zipEntry = new ZipEntry(HelloWorld.class.getName().replace(
 				".", "/")
 				+ ".class");
 		jarOutputStream.putNextEntry(zipEntry);
 		InputStream inputStream = JarFileCreationExample.class
 				.getResourceAsStream("HelloWorld.class");
 		byte[] buffer = new byte[1024];
 		int bytesRead = 0;
 		while ((bytesRead = inputStream.read(buffer)) > 0) {
 			jarOutputStream.write(buffer, 0, bytesRead);
 		}
 		inputStream.close();
 		jarOutputStream.closeEntry();
 		jarOutputStream.flush();
 		jarOutputStream.close();
 	}
 }

Code: 
 /**
  * 
  */
 package de.tutorials;
 
 /**
  * @author Tom
  *
  */
 public class HelloWorld {
 
 	/**
 	 * @param args
 	 */
 	public static void main(String[] args) {
 		System.out.println("Hello World!");
 	}
 
 }

Anschließend in der Konsole:
Code: 
 C:\>java -cp .\tutorials.jar de.tutorials.HelloWorld
 Hello World!

Gruss Tom
 
Ich hab jetz ein Archiev erstellt und die Passende jad gleich mit.

mein Manifest(My.jar)

Manifest-Version: 1.0
MicroEdition-Configuration: CLDC-1.1
MIDlet-Name: MyClass
Created-By: 1.5.0_04 (Sun Microsystems Inc.)
MIDlet-Vendor: RedMoonGames
MIDlet-1: MyClass, , MyClass
MIDlet-Version: 1.0
MicroEdition-Profile: MIDP-2.0

meine Jad(My.jad)

MIDlet-1: My, , My
MIDlet-Jar-Size: 451367
MIDlet-Jar-URL: My.jar
MIDlet-Name: My
MIDlet-Vendor: Ich
MIDlet-Version: 1.0
MicroEdition-Configuration: CLDC-1.1
MicroEdition-Profile: MIDP-2.0

Die grösse der Datei stimmt

Wenn ich jetzt das Midlet per emulator ausführen möchte startet er zwar zunächst aber sobald ich das Midlet starte gibt er eine lange Fehlermeldung aus.
