title: How do I know what version of servlet-api.jar I have?
body: <p>I downloaded a copy of servlet-api.jar from java2s.com.  How do I know what version it is?  There's no reference on the site.</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>Ah.  Apologies.  I should have listed the content of the wordpad output when I double clicked on the MANIFEST.MF file in the jar I got:</p>
  
  <pre><code>Manifest-Version: 1.0
  Ant-Version: Apache Ant 1.6.5
  Created-By: 1.5.0_06-b05 (Sun Microsystems Inc.)
  </code></pre>
  
  <p>As you can see it didnt tell me the version hence the question.</p>
