title: how to escape operators in JSP expressions
body: <p>I am embedding Java code in a piece of JSP on a HTML page:</p>
  
  <pre><code>&lt;c:when test="&lt;%=\"F\".equals(result[1])||\"P\".equals(result[1])%&gt;"&gt;
  </code></pre>
  
  <p>The above code works. Now I need to make <code>"F".equals(result[1])</code> to <code>!("F".equals(result[1]))</code>. How do I do that?</p>
