cannot include external jar in my executable jar

Question

I am trying to convert my java application to an executable jar.

I have been able to package it into a jar with all my class files, but still am not able to include the jmf.jar file.

This is my directory structure,

Main dir

src/                  //A dir
--a.java
--b.java
jmf.jar
Manifest.txt

Content of my Manifest.txt file,

Manifest-Version: 1.0 
Ant-Version: Apache Ant 1.7.0  
Main-Class: src/a
Class-Path: .;jmf.jar //also tried ./jmf.jar

By double clicking the .jar file, I am able to run the main function, but the second function uses the jmf.jar throws exception when I tried running the jar file in debug mode, that javax.media not found. This class is in the jmf.jar file, which makes me conclude the jmf.jar file is not being included in the class path or so. So what am I doing wrong? How do I make this executable file?

The command I used to convert it to jar was,

jar cvfm myJar.jar Manifest.txt src\*.class jmf.jar

Everything looks fine here. Why don't you show us the manifest.mf file. — Optimus Prime

Your commands are in the wrong order. If you have cvfm, you must first specify the file name, then the path to the manifest, and then the directories to JAR up. — gparyani

The jar files referred to by the Class-Path entry in the manifest must not be inside the jar, but outside of it, as explained in the jar tutorial.

Yes, there's the answer, the space not added and classpath wasn't in .mf file.

If you are using JMF you’ll need to include jmf.jar and jmf.properties in the same directory as the executable jar
