Here is the code that the JAX-WS SoapHandler things use for this. This may
help. It MAY require the SAAJOutInterceptor configured in as well. Not
really sure.
Dan
// server side inbound
message.getInterceptorChain().abort();
Endpoint e = message.getExchange().get(Endpoint.class);
if (!message.getExchange().isOneWay()) {
Message responseMsg = new MessageImpl();
responseMsg.setExchange(message.getExchange());
responseMsg = e.getBinding().createMessage(responseMsg);
message.getExchange().setOutMessage(responseMsg);
SOAPMessage soapMessage =
((SOAPMessageContext)context).getMessage();
responseMsg.setContent(SOAPMessage.class, soapMessage);
InterceptorChain chain =
OutgoingChainInterceptor.getOutInterceptorChain(message
.getExchange());
responseMsg.setInterceptorChain(chain);
// so the idea of starting interceptor chain from any
// specified point does not work
// well for outbound case, as many outbound interceptors
// have their ending interceptors.
// For example, we can not skip MessageSenderInterceptor.
chain.doInterceptStartingAfter(responseMsg,
SoapPreProtocolOutInterceptor.class.getName());
}
