Make it easier to detect fault messages when mediating them
-----------------------------------------------------------
Key: SYNAPSE-498
URL: https://issues.apache.org/jira/browse/SYNAPSE-498
Project: Synapse
Issue Type: Improvement
Components: Core
Affects Versions: 1.2
Reporter: Asankha C. Perera
Assignee: Asankha C. Perera
Priority: Minor
Fix For: 1.3
It should be easy to find if a message being mediated upon is an error or a
fault. Currently for SOAP interactions, one may have to write a filter as shown
below to detect a SOAP 1.1 and/or 1.2 fault
<filter xpath="/soap11:Envelope/soap11:Body/soap11:Fault or
/soap12:Envelope/soap12:Body/soap12:Fault"
xmlns:soap11="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:soap12="http://www.w3.org/2003/05/soap-envelope";>
It should also be possible for someone to check for POX and other types of
faults, which maybe indicated by the transport and/or other (possibly within
the payload of a binary message) information as well. e.g. HTTP response code
for POX, custom binary indication for Hessian
One possible way of implementing this is using the get-property() function, and
allowing someone to detect any known fault messages with say a
"get-property('FAULT')" call - which could check for SOAP 1.1/1.2, HTTP
non-2xx, and Hessian faults etc. For HTTP one could also check the status code
via the already available HTTP_SC property on the Axis2 message context level.
