body: <p>I am obliviously new to EL (with Struts 2 specifically). I am updating the current code and I see different types of entries. Whats the difference?</p>
  
  <pre><code>&lt;s:property value="%{obj.field}"/&gt;  // With %{}
  &lt;s:property value="obj.field"/&gt;     // Without %{}
  &lt;s:property value="%{#obj.field}"/&gt; // with %{} and prefixed # 
  ${obj.field}  // with ${}
  // any other types I may have missed...
