CXF Fault interceptor: log useful information

Question

I would like to log some information in case of fault. In particular I'd like to log the ip address and port of the client contacting the server, the username if the security in active, and, if possible, also the incoming message.

I added an interceptor in the getOutFaultInterceptors chain of the endpoint, but in the handleMessage I don't know which properties I can use.

Some ideas?

Thank you

I solved in this way

public FaultInterceptor() {
    super(Phase.MARSHAL);
}

public void handleMessage(SoapMessage message) throws Fault {
    Fault fault = (Fault) message.getContent(Exception.class);
    Message inMessage = message.getExchange().getInMessage();
    if (inMessage == null) return;

    String xmlMessage = null;
    InputStream is = inMessage.getContent(InputStream.class);
    String rawXml = null;
    if (is != null) {
        rawXml = is.toString();
    }

    String username = null;
    if (rawXml != null && rawXml.length() > 0) {
        try {
            XPath xpath = XPathFactory.newInstance().newXPath();
            XPathExpression xpathExpression;

            xpathExpression = xpath.compile("//*[local-name()=\'Envelope\']/*[local-name()=\'Header\']/*[local-name()=\'Security\']" +
                    "/*[local-name()=\'UsernameToken\']/*[local-name()=\'Username\']");

            InputSource source = new InputSource(new StringReader(rawXml));

            username = xpathExpression.evaluate(source);
        } catch (XPathExpressionException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        xmlMessage = XMLUtils.prittyPrinter(is.toString());
    }

    String clientAddress = "<unknown>";
    int clientPort = -1;
    HttpServletRequest request = (HttpServletRequest)inMessage.get(AbstractHTTPDestination.HTTP_REQUEST); 
    if (null != request) {               
        clientAddress = request.getRemoteAddr(); 
        clientPort = request.getRemotePort();
    }

    logger.warn("User: " + username + " [" + clientAddress + ":" + clientPort + "] caused fault: " + fault +
            "\nMessage received: \n" + xmlMessage);



}

I found the "inMessage" property and on it I found the original message (and I can retrieve the username) and the "request" from which I retrieved the host and port.

Thank you.
