to display the exception soap fault xml sent by the client in mule

Question

i have a mule service in which it contains a proxy service and client.When i give request to client it is throwing some exception.while throwing the exception it is sending one soap fault xml in which it contains details tag which i need to display it in the response.I am using inInterceptor in soap client to access the fault and the class used is CheckFaultInterceptor. At present i am able to access only the fault string from soap client.But my requirement is to access the entire soap fault xml.Please help me. my mule configuration.xml is:

Answer 1

Avoiding interceptors in the proxy-client will help in solving this scenario

See the modified flow. This should provide you with the total soap-fault response from the HTTP Outbound call.

<flow name="CreateSrvcReqGSSInvocation" doc:name="CreateSrvcReqGSSInvocation">
    <mulexml:dom-to-xml-transformer
        returnClass="java.lang.String" doc:name="DOM to XML" />
        <logger message="Request to GSS #[message.payload]" level="INFO"
        doc:name="Logger" />
    <cxf:proxy-client doc:name="SOAP"
        enableMuleSoapHeaders="true" payload="envelope">            
    </cxf:proxy-client>
    <mulexml:dom-to-xml-transformer>
        doc:name="DOM to XML"
    </mulexml:dom-to-xml-transformer>
    <http:outbound-endpoint exchange-pattern="request-response"
        method="POST" address="${outbound.gss.sr}" transformer-refs="AddSoapActionHeader"
        doc:name="InvokeGSSCreateSR" responseTimeout="${outbound.gss.sr.responseTimeOutInMillisec}" />
</flow>

Hope this helps.
