title: HTML File upload form with additional input fields
body: <p>I have the following html form...</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;&lt;title&gt;Upload Servlet&lt;/title&gt;&lt;/head&gt;
  &lt;body&gt;&lt;h2&gt;Upload Servlet&lt;/h2&gt;
  
  &lt;form name='uploadparams' enctype='multipart/form-data' action='' method='post'&gt;
      &lt;label&gt;Migrate Options From:
          &lt;select name='migrateFrom'&gt;
              &lt;option&gt;&lt;/option&gt;
              &lt;option value='version 1'&gt;version 1&lt;/option&gt;
          &lt;/select&gt;
      &lt;/label&gt;
      &lt;br/&gt;
      &lt;input type='file' name='zipFile'&gt;
      &lt;br/&gt;
      &lt;input type='hidden' value='willnotshowupinservlet'/&gt;
      &lt;button type='submit'&gt;Submit&lt;/button&gt;
  &lt;/form&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>The problem is that while I can read the file with a http parameter name of "zipFile" just fine my servlet does not see the other parameters "willnotshowupinservlet" and "migrateFrom".  Are file upload forms only able to have one input (the file input)?</p>
