title: Http request.getParameter( fieldname ) with List
body: <p>I see that if an entry form in html has an input type = text ...
  I can read this text as a String with </p>
  
  <pre><code>request.getParameter( fieldname ).
  </code></pre>
  
  <p>But how can I read a List if the select is multiple?</p>
  
  <p>I would like to set an ArrayList in a bean based on more than one parameter.
  Like this</p>
  
  <pre><code>List&lt;String&gt; values = request.getParameter( fieldsList );
  </code></pre>
