Duke$ - Multiple packages in one jar... again

Question

My jar contains 2 packages.
One is my own, the other one is the JNIRegistry from Ice. (Excellent for Windows. Download it at: http://www.trustice.com/java/jnireg/index.shtml )
My application starts from the jar file and works just fine, but as soon as one of my classes tries to import/load a class from the com-package, the NoClassDefFoundError exception is thrown.
I created the jarfile in my app-folder by using:
jar cfm myJarFile.jar manifest.mf myPackage com
This is the folder tree:
C:\
|
|-app
|
|--com (folder)
|
|--myPackage (folder)
|
|--manifest.mf
I have checked the contents of the jarfile, nothing is missing.
This is the manifest file:
Main-Class: myPackage.App
I am sure there must be a way around this... The closest solution I have found was at:
http://forum.java.sun.com/thread.jsp?forum=22&thread=30891
It says specify each class you want to import from the other package, for example dont use
import com.ice.jni.registry.*;
but
import com.ice.jni.registry.Registry;
import com.ice.jni.registry.RegistryKey;
import com.ice.jni.registry.RegStringValue;
So I did. Nothing changed, still the NoClassDefFoundError
Any help?
Thanks in advance

Hey guys,
This is how you do it. I have an example here for you to follow:
-----Test.java
package com.test;
import another.one.*; // note * is ok to use!
class Test
     public static void main(String[] args)
          System.out.println("Hello from Test!");
          Target.main(null);
}------Target.java
package another.one;
public class Target
     public static void main(String[] args)
          System.out.println("Hello from Target!");
}place files like so:
{path}/com/test/Test.java
{path}/another/one/Target.java
compile classes, then create a manifest:
---manifest.txt
Main-Class: com.test.Test
{a blank line here}
place at:
{path}manifest.txt
now create jar;
{path}> jar cmf manifest.txt myJar.jar com/ another/
and enjoy ;-) java -jar myJar.jar
