title: Bean Validation @NotNull, @NotBlank and @NotEmpty does not work in JSF+Tomcat
body: <p>I am using Hibernate Validation annotations in my JSF managed bean. When I use <code>@NotNull</code>, <code>@NotBlank</code> or <code>@NotEmpty</code> they doesn't seem to be triggered in any way.</p>
  
  <pre><code>@NotBlank(message = "{name.required}")
  public String name;
  </code></pre>
  
  <p>View:</p>
  
  <pre><code>&lt;h:outputLabel value="Name:" /&gt; 
  &lt;h:inputText id="name" value="#{person.name}" size="20" /&gt;
  &lt;h:message for="name" style="color:red" /&gt;
  </code></pre>
  
  <p>How is this caused and how can I solve it?</p>
