Cannot reply or makefault when client sends malformed XML - org.apache.axiom.om.OMException: com.ctc.wstx.exc.WstxParsingException
----------------------------------------------------------------------------------------------------------------------------------
Key: SYNAPSE-849
URL:
https://issues.apache.org/jira/browse/SYNAPSE-849 Project: Synapse
Issue Type: Bug
Components: Script mediator
Affects Versions: 2.0
Environment: Mac OS X 10.7.3
Linux version 2.6.18-238.19.1.el5
(issue not specific to OS/HW - getting on Mac, Linux, Windows)
Reporter: Isobel Novak
Fix For: 2.0
When client sends malformed XML to Synapse service, getting "org.apache.axiom.om.OMException: com.ctc.wstx.exc.WstxParsingException exception" when accessing the payload to parse it/transform it, etc.
After this exception is raised, you cannot mediate the message further, or use makefault to return response to the client.
Attempting to makefault after hitting this error only returns the same error 'org.apache.axiom.om.OMException: com.ctc.wstx.exc.WstxParsingException'. Cannot makefault.
We want to be able to return a fault response to the client when they send malformed xml. How to do this?
Right now, when this exception is raised, we can only log a custom text message and drop the message, but cannot return a fault response.
Dropping the message returns 'HTTP 202 Accepted' response, which isn't really the right response in this case. We'd like to return fault response or at least HTTP 400 'Bad request'.
