Stuck: What interceptor unmarshals qnames back into java objects?
I'm attempting to write my first interceptor, but having trouble getting of
the ground. It's basically a custom logger that takes attributes from the
request/response and writes them to a database our DBA's have created for
me.
I chose the interceptor route because it is easily enabled/disabled in the
Spring config, and we want to use it across many of our webservices without
changing the webservice code.
These are SOAP services over Http.
First, my interceptor class declaration:
public class SimpleUsageTrackingCXFInterceptor implements
PhaseInterceptor<Message>
public void handleMessage(Message soapMessage) throws Fault {
....
}
soapMessage has a ton of methods. I need to get a handle to the Java objects
the XML represents. if I call Message.getValues() I get a bunch of QName
objects. Is there a better method to use to get the unmarshalled objects?
I've read through the mailing list that where I insert my interceptor in the
chain has a lot to do with this... I've tried setting breakpoints in
PhaseInterceptorChain but It's really not clicking. Is there a particular
interceptor I should insert my interceptor after?
I'm not asking for someone to write my code, just a stern shove in the
correct direction. Thanks for any help guys!

It would be one of the subclasses of AbstractInDatabindingInterceptor.
USUALLY that would be DocLiteralInInterceptor, but it could also be the
RPCInInterceptor or others.
In anycase, to get the List of params, you would normally do:
MessageContentsList lst = MessageContentsList.getContentsList(message);
(which really just does msg.getContent(List.class) and double checks the
class
and such)
However, what's in there could also depend on where in the chain your
interceptor lives and whether you use jaxws or not. If you put it
immediately after the DocLiteralInInterceptor (unmarshal phase), it
would
probably have a single object in it being the wrapper object. If you
move
your interceptor to POST_LOGICAL and after the
WrapperClassInInterceptor, the
list would have the individual parts.
