Hi, Simon,

I did try what you described here and it worked - afterInvoke is called
with respnseMC that contains the fault SOAP message. So it's doable.
Here's the code snippet.

        try {
            AccessController.doPrivileged(new
PrivilegedExceptionAction<Object>() {
                public Object run() throws AxisFault {
                    operationClient.execute(true);
                    return null;
                }
            });
        } catch (PrivilegedActionException e) {
                MessageContext responseMC = 
        
operationClient.getMessageContext(WSDLConstants.MESSAGE_LABEL_IN_VALUE);
        
                for ( PolicyHandler policyHandler : policyHandlerList )
{
                policyHandler.afterInvoke(msg, responseMC,
operationClient);
                }            
                operationClient.complete(requestMC);
            throw (AxisFault)e.getException();
        }

Thanks,
