title: How to debug JSTL?
body: <p>I'm using SpringSource Tool Suite (with Roo) and have some success.
  What bothers me though is that I don't know how to debug tag library-stuff.</p>
  
  <p>I may add breakpoints but it never stops at them.</p>
  
  <p>What I'm looking for is a dump of all current variables in the context.</p>
  
  <p>Up until now I did something like:</p>
  
  <pre><code>&lt;c:forEach items="${data}" var="item"&gt;
      &lt;c:out value="${item}"&gt;&lt;/c:out&gt;&lt;br /&gt;
  &lt;/c:forEach&gt;
  </code></pre>
  
  <p>Sadly, that's difficult to read and also not pretty straightforward.</p>
  
  <p>What can I do to improve this?</p>
