Custom handling of exceptions and SOAP faults with CXF

[Pascal Ognibene]

Hi,

I've written a web service implementation (wsdl first) using CXF. This 
service can throw exceptions. Currently they're automatically caught by 
CXF and mapped to a SOAP fault, but I want to include additional 
informations in the SOAP fault message.

I tried with CXF Soap11FaultOutInterceptor, but I only have a Message as 
input; the original exception is not available. And I need it to extract 
informations from this exception and build a custom Fault message.

Basically what I have now is something like:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";>
   <soap:Body>
      <soap:Fault>
         <faultcode>soap:Server</faultcode>
         <faultstring>Fault occurred while processing.</faultstring>
      </soap:Fault>
   </soap:Body>
</soap:Envelope>

And what I would like to get is:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";>
   <soap:Body>
      <soap:Fault>
         <faultcode>soap:Server</faultcode>
         <faultstring>1234|param1|param2|param3</faultstring>
      </soap:Fault>
   </soap:Body>
</soap:Envelope>

Where the fault string is custom built using data extracted from the 
initial exception.

BTW I'm using CXF with Spring; don't know if it has an impact.

Any help is welcome.
