title: Expression Value in Jasper Report: "Cannot cast from String to Boolean" error
body: <p>This is my expression code:</p>
  
  <pre><code>($F{Personel_ODEME}.equals(Boolean.TRUE)) ? "PAID" : "NO PAID"
  </code></pre>
  
  <p>If Personel is paid, her/his Jasper tax report will read <code>PAID</code>, otherwise <code>NO PAID</code>. In the DB, this field is Boolean type, but the expression is returning a String type. So I am getting a <code>Cannot cast from String to Boolean</code> error.</p>
