title: Empty soapAction in generated WSDL
body: <p>I'm trying to generate a WSDL from my Java code using JAX-WS.</p>
  
  <p>Everything seems to work OK, except that for my operations in the WSDL the soapAction remains empty.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>@WebService
  public class MyClass {
      public MyStuff queryStuff(String myParam) {
          return null;
      }
  }
  </code></pre>
  
  <p>The generated WSDL contains this:</p>
  
  <pre><code>&lt;wsdl:operation name="queryStuff"&gt;
      &lt;wsdlsoap:operation soapAction=""/&gt;
      &lt;wsdl:input name="queryStuffRequest"&gt;
          &lt;wsdlsoap:body use="literal"/&gt;
      &lt;/wsdl:input&gt;
      &lt;wsdl:output name="queryStuffResponse"&gt;
          &lt;wsdlsoap:body use="literal"/&gt;
      &lt;/wsdl:output&gt;
  &lt;/wsdl:operation&gt;
  </code></pre>
  
  <p>I can't tell what I'm doing wrong. Any ideas?</p>
