title: Griffon rest plugin giving org.apache.xerces.parsers.AbstractSAXParser class not found ..
body: <p>First opportunity i've had to use Griffon in a real application and i'm following the GIA book trying the example with Griffon in the front and Grails in the back  .. I've build the app  but can't get the Griffon front end to run .. The code .. </p>
  
  <pre><code>void populateModel(model) {
      withRest(id: 'bookstoreREST',
              uri: 'http://localhost:8080/bookstore/') {
          def response = get(path: 'author')
  </code></pre>
  
  <p>is throwing java.lang.NoClassDefFoundError: org/apache/xerces/parsers/AbstractSAXParser
      at groovyx.net.http.ParserRegistry.parseHTML(ParserRegistry.java:235)</p>
  
  <p>which corresponds to the line defining the response .. I can access it directly from the background Grails app  .. Do i need to install something else other than the Rest plugin to make this work ? Currently using Griffon 1.5  .. </p>
  
  <p>Thanks </p>
