Error in WSO2 ESB when calling service without Header element

Question

I believe I found bug in WSO2 ESB.

I defined proxy service for our customer. With security turned off I always get expected result, but when I enable security (scenario 1 - UsernameToken), then I get error "SOAP Envelope can not have children other than SOAP Header and Body".

I'm able to reproduce this bug with 'echo' service.

Here is request:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:echo="http://echo.services.core.carbon.wso2.org">
  <soap:Body>
    <echo:echoString>    
       <in>ABC</in>
    </echo:echoString>
  </soap:Body>
</soap:Envelope>

Turning security off or adding <soap:Header /> element before <soap:Body> element provides expected response again.

I'm using WSO2 ESB version 4.8.1, SoapUI 5.0.0 as client.

The SOAP headers contain application specific information related to the SOAP message. They typically contain routing information, authentication information, transaction semantics etc.

If you removed <soapenv:Header/> SoapUI will not send your user name and password to rampart.

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:echo="http://echo.services.core.carbon.wso2.org">
   <soapenv:Header/>
   <soapenv:Body>
      <echo:echoString>
         <!--Optional:-->
         <in>ABC</in>
      </echo:echoString>
   </soapenv:Body>
</soapenv:Envelope>

So your error was return by org.apache.axiom.soap.SOAPProcessingException due to AxisEngine System error.

When your sending request to secured one header is must..
