body: <p>I'm using apache-camel and this is my first deployment of a bundle to karaf. I want to catch <code>HttpOperationFailedException</code>: </p>
  
  <pre><code>&lt;doCatch id="catch-http_request"&gt;
    &lt;exception&gt;org.apache.camel.http.common.HttpOperationFailedException&lt;/exception&gt;
    &lt;to id="prepareRespAcc_http" uri="bean:com.ngtrend.lcmwbmadmin.WBResponseHandler?method=prepareResponseAcc(400,${body})"/&gt; 
    &lt;log id="log-wb-account-params" loggingLevel="INFO" message="wbm admin query params: ${body}"/&gt;
    &lt;log id="log-catch-http-error" loggingLevel="ERROR" message="Sending bad Request : ${exception.message}"/&gt;  
  &lt;/doCatch&gt; 
  </code></pre>
