title: How to change the alias of a key within a keystore?
body: <p>I signed my JWS application <a href="http://memorizeasy.mysimpatico.com" rel="noreferrer">MemorizEasy</a> with a key whose alias is:</p>
  
  <pre><code>memofile.reference.emma.jar=/Users/simpatico/.netbeans/6.8/modules/ext/emma.jar
  </code></pre>
  
  <p>I don't remember why I chose such a long alias. I suspect it was memo only, but in my project settings I have:</p>
  
  <pre><code>jnlp.signjar.alias=memofile.reference.emma.jar=/Users/simpatico/.netbeans/6.8/modules/ext/emma.jar
  </code></pre>
  
  <p>I'm now updating the application and using maven I need to specify the alias as:</p>
  
  <pre><code>&lt;keystorealias&gt;memofile.reference.emma.jar=/Users/simpatico/.netbeans/6.8/modules/ext/emma.jar
  &lt;/keystorealias&gt;
  </code></pre>
  
  <p>Yet that doesn't work. Trying another key with alias <code>mjee</code> it works. </p>
  
  <p>So could I change the alias of the key? If so, how?
  Otherwise, why wouldn't Maven accept my alias?</p>
