Modifying SOAP:Fault errors raised by endpoints

[Jim Talbut]

Hi,

I have a route that looks like this:
                from( sourceEndpoint )
                        .onException( java.lang.Throwable.class 
).process( new Processor() {
                                public void process(Exchange exchange) 
throws Exception
                                {
                                    log.warn( "onException\n\n\n\n" );
                                    Throwable caused = 
exchange.getProperty(Exchange.EXCEPTION_CAUGHT, Throwable.class);
                                    log.info( "caused = " + 
caused.getClass().getCanonicalName() );
                                    log.info( "caused = " + 
caused.getMessage() );
                                    log.info( "caused = " + 
caused.toString() );
                                    log.info( "caused = " + caused );
                                }
                            }).end()
                        .to( destinationEndpoint );
Both sourceEndpoint and destinationEndpoint are CXF endpoints.
When destinationEndpoint is unavailable (the server is down) the 
onException handler is thrown correctly.

But if destinationEndpoint returns a SOAP:Fault onException isn't 
triggered and I can't find out how to modify the SOAP:Fault that the 
clients of sourceEndpoint receive.
I need to ensure that SOAP:Server faults are modified before being 
returned to the client.

I tried adding a processor, but that only gets called on the way In, 
whether it returns a fault or not.

I'm new to camel but I've managed to get most of my requirements met, 
leaving me with just this problem that's got me completely stumped.

Thanks

Jim
