Accessing SOAP fault code and fault message via Axis2/Axiom-API does not work
-----------------------------------------------------------------------------
Key: ESBJAVA-522
URL: https://wso2.org/jira/browse/ESBJAVA-522
Project: WSO2 ESB
Issue Type: Bug
Affects Versions: 1.7
Reporter: Eric Hubert
Assignee: Asankha Perera
Priority: Blocker
We are using the following code to access SOAP faultcode and faultstring:
if (axis2MessageCtx.getEnvelope().getBody().getFault() != null) {
SOAPFault fault = axis2MessageCtx.getEnvelope().getBody().getFault();
OMElement faultcode = (OMElement) fault.getChildrenWithName(new
QName("faultcode")).next();
messagePropertyDTO.setFaultCode(faultcode.getText());
OMElement faultmessage = (OMElement) fault.getChildrenWithName(new
QName("faultstring")).next();
messagePropertyDTO.setFault(faultmessage.getText());
}
it works with WSO2 ESB 1.7 Beta-2. In the proposed final version we get the
following exception:
2008-06-09 10:20:24,261 [127.0.0.1-berjbolle-lx1] [HttpServerWorker-1] INFO

One other problem we noticed on the way is a strange behaviour of
getChildrenWithLocalName(). If we changed the above code in 1.7 Beta 2 to this:
if (axis2MessageCtx.getEnvelope().getBody().getFault() != null) {
SOAPFault fault = axis2MessageCtx.getEnvelope().getBody().getFault();
OMElement faultcode = (OMElement)
fault.getChildrenWithName("faultcode").next();
messagePropertyDTO.setFaultCode(faultcode.getText());
OMElement faultmessage = (OMElement)
fault.getChildrenWithName("faultstring").next();
messagePropertyDTO.setFault(faultmessage.getText());
}
getChildrenWithName() always returned the first Element. No matter of the
specified string. It could also be "abc" which was not present. I would also
consider this to be a bug.
