How to retrieve return value in out interceptor?
Hi,
I want to filter some return values in an out interceptor, but am
struggling to figure out how to retrieve it.
I have tried this:
MessageContentsList outObjects =
MessageContentsList.getContentsList(message);
Exchange exchange = message.getExchange();
OperationInfo op = exchange.getBindingOperationInfo() == null
? null
: exchange.getBindingOperationInfo().getOperationInfo();
and see a lot of info...but can't figure out how to retrieve the _return
value I see in the xxx.jaxws_asm
Any pointers?

Hi
You can use JAX-RS 2.0 ContainerResponseFilter with 2.0 ResourceInfo [1]
context injected into it. Or access Response annotations (method
annotations by default) directly from ContainerResponseFilter response
context.
In a pure CXF out interceptor you can get it from the exchange:
OperationResourceInfo ori = exchange.get(OperationResourceInfo.class);
ori.getMethodToInvoke();

Thanks, Dan!
One more question, how do I retrieve the method called (I need to retrieve
the annotations from it) if it's a JAX-RS method?
I have used this for in interceptors, but doesn't seem to be working for
out interceptor:
private Method getTargetMethod(Message m) {
BindingOperationInfo bop =
m.getExchange().get(BindingOperationInfo.class);
if (bop != null) {
MethodDispatcher md = (MethodDispatcher)
m.getExchange().get(Service.class).get(MethodDispatcher.class.getName());
return md.getMethod(bop);
}
return (Method)m.get("org.apache.cxf.resource.method");
}

Move your interceptor up into the PRE_LOGICAL with a addBefore(WrapperClassOutInterceptor.class.getName()). The list should then just have the return value (and any holders for other outs). The WrapperClassOutInterceptor combines those into the asm generate object.
