For Oracle BPEL to be able to catch SOAP faults thrown using the SOA-Direct binding, the SOAP Fault has to follow some guidelines. Suppose your service is defined by the following WSDL port and has a namespace of http://www.example.org/MyService:

<wsdl:portType name="MyServicePortType">
<wsdl:operation name="Execute">
<wsdl:input message="exp:ExecuteRequestMsg"/>
<wsdl:output message="exp:ExecuteResponseMsg"/>
<wsdl:fault name="executeFault" message="exp:ExecuteFaultMsg"/>
<wsdl:fault name="genericFault" message="exp:GenericFaultMsg"/>
</wsdl:operation>
</wsdl:portType>

When throwing a SOAP Fault, you must include the qualified name of the fault as declared in the WSDL port. For SOAP 1.1 messages, the QName of the WSDL port fault should be included in the faultcode element as seen bellow:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
	<soapenv:Body>
		<soapenv:Fault xmlns:ns0="http://www.example.org/MyService">
		<faultcode>ns0:genericFault</faultcode>
		<faultstring/>
		<faultactor/>
		<detail>
			<GenericFault xmlns="http://www.example.org/FaultInfo">
			<FaultInfo>
				<ErrorDescription>Error - soap1.1</ErrorDescription>
			</FaultInfo>
			</GenericFault>
		</detail>
		</soapenv:Fault>
	</soapenv:Body>
</soapenv:Envelope> 

For SOAP 1.2 messages, the QName of the WSDL port fault should be included in the Code/Subcode/Value element as seen below:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
	<soap:Header xmlns:exem="http://www.example.org/MyService"/>
	<soap:Body xmlns:exem="http://www.example.org/MyService">
		<soap:Fault>
			<soap:Fault>
				<soap:Value>soap:Receiver</soap:Value>
				<soap:Subcode>
					<soap:Value  xmlns:ns1=" soap:value>"="" target="_blank">http://www.example.org/MyService">ns1:genericFault</soap:Value>
				</soap:Subcode>
			</soap:Code>
			<soap:Reason>
				<soap:Text xml:lang="pt">Failure calling partner.</soap:Text>
			</soap:Reason>
			<soap:Node>...</soap:Node>
			<soap:Detail>
				<err:GenericFault xmlns:err="http://www.example.org/FaultInfo">
					<err:FaultInfo>
						<err:ErrorDescription>Error Desc</err:ErrorDescription>
					</err:FaultInfo>
				</err:GenericFault>
			</soap:Detail>
		</soap:Fault>

	</soap:Body>
</soap:Envelope>
