title: Reference jars inside a jar
body: <p>I have a jar whose content looks as shown below,</p>
  
  <p><img src="https://i.stack.imgur.com/L24vd.png" alt="enter image description here"></p>
  
  <p>Below is my manifest file</p>
  
  <pre><code>Manifest-Version: 1.0
  Ant-Version: Apache Ant 1.8.3
  Created-By: 1.7.0_06-b24 (Oracle Corporation)
  Main-Class: org.sai.com.DerbyDemo
  Class-Path: derby.jar derbyclient.jar derbynet.jar derbytools.jar
  </code></pre>
  
  <p>When i try to run the jar, it has thrown a <code>ClassNotFoundExcception</code> meaning it isn't referencing the jars inside the outer jar.</p>
  
  <p>In the <code>Class-Path</code> attribute, how can I reference jars (<code>derby.jar</code>, etc) inside the actual jar?</p>
