The pattern of using the SAAJ interceptor like that really only works for the
incoming side. For the outgoing side, you would need to break the
interceptor into two parts. Something like:
public class HelloOutboundInterceptor extends AbstractSoapInterceptor{
private SAAJOutInterceptor saajOut = new SAAJOutInterceptor ();
public HelloOutboundInterceptor(){
super(Phase.PRE_PROTOCOL);
addAfter(SAAJOutInterceptor.class.getName());
}
public void handleMessage(SoapMessage message) throws Fault {
//make sure the saaj model is setup
getSOAPMessage(message);
//add the ending interceptor to do the work
message.getInterceptorChain().add(new EndingInterceptor());
}
static class EndingInterceptor extends AbstractSoapInterceptor {
public EndingInterceptor() {
super(Phase.PRE_PROTOCOL_ENDING);
addBefore(SAAJOutEndingInterceptor.class.getName());
}
public void handleMessage(SoapMessage message) throws Fault {
//your logic here
}
}
}
THAT said, it may be better to just use an interceptor early in the chain
(like USER_LOGICAL) to build up a DOM for your specific header and just do:
Header header = new Header(qname, dom);
message.getHeaders().add(header);
and CXF would automatically add the header to the output during writing
without having to deal with the saaj tree.
