title: Could not find jaxws21 frontend within classpath
body: <p>For various reasons I need to try out the jaxws21 frontent in my build. So I followed the tip on <a href="https://stackoverflow.com/a/14113078/1864054">this answer</a>, adding to the wsdl options:</p>
  
  <pre><code>                &lt;extraargs&gt;
                      &lt;extraarg&gt;-fe&lt;/extraarg&gt;
                      &lt;extraarg&gt;jaxws21&lt;/extraarg&gt;
                  &lt;/extraargs&gt;
  </code></pre>
  
  <p>But my build complains: </p>
  
  <blockquote>
    <p>Could not find jaxws21 frontend within classpath</p>
  </blockquote>
  
  <p>How do I resolve this?</p>
  
  <p>BTW, my pom.xml includes:</p>
  
  <pre><code>&lt;dependency&gt;
      &lt;groupId&gt;javax.xml.ws&lt;/groupId&gt;
      &lt;artifactId&gt;jaxws-api&lt;/artifactId&gt;
      &lt;version&gt;2.2.8&lt;/version&gt;
  &lt;/dependency&gt;
  </code></pre>
  
  <p>Could this be the culprit? If so, which version should I be changing it to?</p>
  
  <p><strong>UPDATE:</strong> I tried changing (in that dependency) <code>2.2.8</code> to <code>2.1</code> but I am still getting this same exact error.</p>
