title: receiving xml with value null when it's actually null
body: <p>I'm executing a stored procedure on sql server 2005 from livecycle es 8.2</p>
  
  <p>the result return something like</p>
  
  <pre><code>&lt;Table&gt;
  &lt;Row&gt;
      &lt;ID&gt;1&lt;/ID&gt;
      &lt;EN_Cd&gt;EN&lt;/EN_Cd&gt;
      &lt;FR_Cd&gt;null&lt;/FR_Cd&gt;
      &lt;EN_Nm&gt;English&lt;/EN_Nm&gt;
      &lt;FR_Nm&gt;Anglais&lt;/FR_Nm&gt;
      &lt;EN_Shrt_Dscrptn&gt;null&lt;/EN_Shrt_Dscrptn&gt;
      &lt;FR_Shrt_Dscrptn&gt;null&lt;/FR_Shrt_Dscrptn&gt;
  &lt;/Row&gt;
  &lt;/Table&gt;
  </code></pre>
  
  <p>I'm trying to figure out why the word "null" is put in the result.</p>
  
  <p>Even with type xs:int it return the word "null"</p>
  
  <p>is there something in the jdbc or livecycle that can fix this?</p>
  
  <p>the stored procedure is a simple</p>
  
  <pre><code>   select id, en_cd, fr_cd, 
            en_nm, fr_nm, 
            en_shrt_dscrptn, fr_shrt_dscrptn 
     from language
  </code></pre>
  
  <p>fr_nm, en_shrt_dscrptn, fr_shrt_dscrptn are null in the database, they do not contain the value "null".</p>
