title: Add messages with Spring
body: <p>I have seen that I can add errors and render them via <code>&lt;form:errors /&gt;</code> tag and <code>addError()</code> method of <code>BindingResult</code> class, but I wonder if there is something similar to send information messages to the JSP.</p>
  
  <p>I mean, I want to add messages when the operation has been successful. I know I could do it by sending an error, but it would make no sense to me to add errors when there haven't been any error at all.</p>
