Fault Handling in Mediator

Question

Hi,
We have a DBAdpater to retrieve the data and a mediator to invoke the DBAdapter. In cases like No Records we want to create a soap fault. So we implemented Mediator Java callout and overriden postRouting() to read the response message and create a soapfault.
[ we referred to blog http://technology.amis.nl/blog/6669/soa-suite-11g-introducing-mediator-java-callouts-for-debug-audit-and]
but when we tried creating SOAPFault and add it to the response message, while execution , the response message is being parsed and seeing the fault it is throwing the exception below:
java.lang.Exception: oracle.sysman.emSDK.webservices.wsdlapi.SoapTestException:
This is a fault.

I found that if exception from mediator is not handled, then the exception is throw as system fault as shown above.
So we tried implementing external fault handling - by creating fault-policies.xml and fault-bindings.xml and a java callout.
fault-bindings.xml
<?xml version=”1.0" encoding=”UTF-8"?>
<faultPolicyBindings version=”2.0.1" xmlns=”http://schemas.oracle.com/bpel/faultpolicy”>
<composite faultPolicy=”SOM_ServiceFaults”/>
</faultPolicyBindings>
fault-policies.xml
<?xml version="1.0" encoding="UTF-8"?>
<faultPolicies>
<faultPolicy version="2.0.1" id="SOM_ServiceFaults">
<Conditions>
<faultName xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" name="env:Fault"> <!-- Qname of Business/SOAP fault -->
<condition>
     <action ref="ora-custom"/>
</condition>
</faultName>
<faultName xmlns:medns="http://schemas.oracle.com/mediator/faults" name="medns:mediatorFault">
<condition>
<action ref="ora-custom"/>
</condition>
</faultName>
</Conditions>
<Actions>
<Action id=”ora-terminate”>
          <abort/>
     </Action>
<Action id="ora-custom">
<javaAction className="gm.som.FaultPolicyJavaAction" defaultAction="ora-terminate">
<returnValue value="ora-terminate" ref="ora-terminate"/>
</javaAction>
</Action>
</Actions>
</faultPolicy>
</faultPolicies>
But still getting the error.Appreciate any help on this.
Thanks in Advance,

Not exactly but doing it the other way around by copying the fault msg to output variable and check flag for the response in my initial requester process then throw fault accordingly.. didnt have much time as it was holding back my other deliverables
Thanks a lot for your time
