Thank you for the information. It isn't quite solving my issue though. What I am trying to do is to log the values in my request stream. My request looks like this:
<?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:xsd="http://www.w3.org/2001/XMLSchema"; xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";> <soap:Body> <getChannel> <session> <sessionUser>123</sessionUser> <sessionGuid>ABC123DEF456</sessionGuid> </session> <channelid>1</channelid> </getChannel> </soap:Body> </soap:Envelope> The inputs are a custom session class I created, and a long I want my interceptor to get out -The name of the service -The name of the method -The session as an object -The channel id as an object I want to be able to do this all in one interceptor, and I do not want to make it a high Impact operation as it would be done in every call and written to a log. I tried your example and the body comes through as null always. I have been doing this: List body = msg.getContent(List.class); mySession sess = (mySession)body.get(0); Which is not ideal. I would like to access the input generically - in so much that I want to pull named parameters from a variety of different calls (some called channelId, some userId, etc) and I am looking to be able to either sniff for these items trivially (they are not always in there) if possible. There will always be a mySession type object that has two fields in it, but I don't know if it will always be first. So, with this in mind, can you provide more guidence. I am doing this currently in the invoke phase.

Please let me know if there is anything missing or still not clear on this page. I am not sure what type of parameters you want to access through interceptors, lets presume you want to access the java parameter objects that are used to invoke the SEI operations. For example, for an operation whose signature is "String sayHi(String input)", you may want to access the value of input before sayHi is invoked. In this case, basically what you need to do is: 1. Write an interceptor according to the instruction [1]. 2. The java parameter objects are only available after a certain interceptor. To figure out exactly what phase your interceptor need to sit in, you need to understand what happens along the interceptor chain. Basically when the request comes in, it is available as an InputStream, then a StaxReader is created in StaxInInterceptor to read this InputStream. The flow in the interceptor chain keeps moving. If the incoming request is a soap message, the soap headers will be stripped off by some intercetors, then the soap body. The content of soap body will be marshaled into java objects by either JAXB data binding or Aegis data binding by data binding interceptors. Finally the ServiceInvokerInterceptor is invoked which will in turn dispatch the request to "sayHi". In your case, I believe adding your interceptor before ServiceInvokerInterceptor should do the trick. 3. The java parameter objects can be accessed from Message. Eg: public class MyInterceptor extends AbstractPhaseInterceptor<Message> { public MyInterceptor () { super(Phase.INVOKE); } public void handleMessage(final Message message) { Object invokee = message.getContent(List.class); if (invokee == null) { invokee = message.getContent(Object.class); } ......... } } To understand more about CXF interceptor chain, I would suggest you do a quick debugging to see how the message flows along the interceptor chain.
