title: how to test multiple conditions in <c:if> jstl
body: <p>I want to check multiple conditions inside the <code>&lt;c:if&gt;</code> tag.
  I am doing it like this</p>
  
  <pre><code>&lt;c:if test="${role ne manager || role ne admin || role ne moderator}"&gt;
    System.out.println("this result will not display for manager, admin &amp; mod");
  &lt;/c:if&gt;
  </code></pre>
  
  <p>But still, I am able to see the result for above roles</p>
