title: Soap web service not displaying nulls
body: <p>I'm making a SOAP service. The structure looks like this:</p>
  
  <pre><code>&gt;             &lt;Person&gt;
  &gt;                 &lt;contactID&gt;122&lt;/contactID&gt;
  &gt;                 &lt;firstName&gt;Jimmy&lt;/firstName&gt;
  &gt;                 &lt;middleName&gt;T.&lt;/middleName&gt;
  &gt;                 &lt;suffix&gt;Jr.&lt;/suffix&gt;
  &gt;                 &lt;emailAddress&gt;jim@m.net&lt;/emailAddress&gt;
  &gt;                 &lt;birthDate&gt;1969-09-01T00:00:00-07:00&lt;/birthDate&gt;     
  &gt;             &lt;/Person&gt;
  </code></pre>
  
  <p>If the birthdate is null, my service will omit that node giving a response like the folowing:</p>
  
  <pre><code>&gt;             &lt;Person&gt;
  &gt;                 &lt;contactID&gt;122&lt;/contactID&gt;
  &gt;                 &lt;firstName&gt;Jimmy&lt;/firstName&gt;
  &gt;                 &lt;middleName&gt;T.&lt;/middleName&gt;
  &gt;                 &lt;suffix&gt;Jr.&lt;/suffix&gt;
  &gt;                 &lt;emailAddress&gt;jim@m.net&lt;/emailAddress&gt; 
  &gt;             &lt;/Person&gt;
  </code></pre>
  
  <p>I need something that states that is null like:</p>
  
  <pre><code>&gt;             &lt;Person&gt;
  &gt;                 &lt;contactID&gt;122&lt;/contactID&gt;
  &gt;                 &lt;firstName&gt;Jimmy&lt;/firstName&gt;
  &gt;                 &lt;middleName&gt;T.&lt;/middleName&gt;
  &gt;                 &lt;suffix&gt;Jr.&lt;/suffix&gt;
  &gt;                 &lt;emailAddress&gt;jim@m.net&lt;/emailAddress&gt;
  &gt;                 &lt;birthDate&gt;null&lt;/birthDate&gt;     
  &gt;             &lt;/Person&gt;
  </code></pre>
  
  <p>I'm using java and glassfish. is it possible to accomplish this? by the way, birthDate is a Date.
  Thank you</p>
