title: Try echo service WSO2 ESB
body: <p>I try the echo service in WSO2 ESB. I send this message:</p>
  
  <pre><code>&lt;body&gt;
      &lt;p:echoInt xmlns:p="http://echo.services.core.carbon.wso2.org"&gt;
          &lt;!--0 to 1 occurrence--&gt;
          &lt;in&gt;1&lt;/in&gt;
      &lt;/p:echoInt&gt;
  &lt;/body&gt;
  </code></pre>
  
  <p>And then, the example service return this error:</p>
  
  <pre><code>&lt;TryitProxyError xmlns:h="http://wso2.org/ns/TryitProxy" h:status="SOAP envelope error"&gt;org.apache.axis2.AxisFault: null&lt;/TryitProxyError&gt;
  </code></pre>
  
  <p>Addition, in the service dashboard (echo) I get this url to the endpoints:</p>
  
  <pre><code>https://null:8245/services/echo
  http://null:8282/services/echo
  </code></pre>
  
  <p>I do not know if both problems have relationship.</p>
