Intercept Web Service invocation fault
Hi,
In a BPEL process, I invoke a Web Service which can return a fault.
I try to propagate this error to the output of my BPEL process.
That I have done :
<ext:failureHandling xmlns:ext="
http://ode.apache.org/activityRecovery">
<ext:faultOnFailure>true</ext:faultOnFailure>
</ext:failureHandling>
...
<bpel:faultHandlers>
<bpel:catchAll>
<bpel:sequence>
<bpel:rethrow />
<bpel:exit />
</bpel:sequence>
</bpel:catchAll>
</bpel:faultHandlers>
...
<bpel:invoke ....>
<bpel:catchAll><bpel:sequence>
<bpel:rethrow />
</bpel:sequence></bpel:catchAll>
</bpel:invoke>
Currently, this process propagate an "Activity failure" fault, and not the
real fault received from the invoked web service.
Ho to do ?
Best regards,
Rudy

Denis,
I'm a bit familiar with SOAP faults (maybe you are using pure HTTP request-response, and it that case, I don't know at all if fault handling works fine).
Note, as I know (?):
"<ext:faultOnFailure>true</ext:faultOnFailure>"
Will make the workflow state to be fault, but it is not mandatory if the workflow catching is a "normal" activity of the workflow.
You should declare your faultHandlers inside a scope (see below). The faultVariable is the name of the variable where goes the SOAP fault message, the faultMessageType is the definition name declared in your WSDL. Check that your service Exception is a real SOAP fault (see below a typical SOAP fault sample) and the following sample code works fine with SOAP exception (in that sample, it put the SOAP exceptionReport element inside another variable (which is used to send to another service).
I hope it helps (sorry if I gave wrong information),

In your BPEL file:
<bpel:faultHandlers>
<bpel:catch faultVariable="WPSG-SSEGRIDexceptionReportFaultVar" faultMessageType="WPSG-SSEGRID:exceptionReport">
<bpel:scope bpmn:label="Sync. Exception handling" name="Sync._Exception_handling" bpmn:id="_gPDQsEgeEeGe7ZsdO5vehw">
[...]
<bpel:copy>
<bpel:from>$WPSG-SSEGRIDexceptionReportFaultVar.exception</bpel:from>
<bpel:to>$mpiwpsgExecuteResponseCallbackRequestMsg.parameters/wps:Status/wps:ProcessFailed/ows:ExceptionReport</bpel:to>
</bpel:copy>
In WSDL operation bindings:
<wsdl:fault name="ExceptionReport">
<soap:fault use="literal" name="ExceptionReport"/>
</wsdl:fault>
In operation portType definition:
<wsdl:fault name="ExceptionReport" message="wpsx:exceptionReport"></wsdl:fault>
In WSDL message definitions (as example):
<wsdl:message name="exceptionReport">
<wsdl:part name="exception" element="ows:ExceptionReport"/>
</wsdl:message>
Sample SOAP fault message:
<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope"
xmlns:m="http://www.example.org/timeouts"
xmlns:xml="http://www.w3.org/XML/1998/namespace">
<env:Body>
<env:Fault>
<env:Code>
<env:Value>env:Sender</env:Value>
<env:Subcode>
<env:Value>m:MessageTimeout</env:Value>
</env:Subcode>
</env:Code>
<env:Reason>
<env:Text xml:lang="en">Sender Timeout</env:Text>
</env:Reason>
<env:Detail>
<m:MaxTime>P5M</m:MaxTime>
</env:Detail>
</env:Fault>
</env:Body>
</env:Envelope>

Looking at the process, it's hard to figure out the reason.
Can you attach the console log related to "Activity failure" ?
