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.
