Hi,

Because CXF write the XML message without using the SOAPMessage write method to write the message, so setting the SOAPMessage.WRITE_XML_DECLARATION to be true doesn't help you.

Here is CXF interceptor that did the trick, it will tell StaxOutInterceptor to write the xml start document for you.

public class WriteXmlDeclarationInterceptor extends AbstractPhaseInterceptor<SoapMessage> {
    public WriteXmlDeclarationInterceptor() {
        super(Phase.PRE_STREAM);
        addBefore(StaxOutInterceptor.class.getName());
    }

    public void handleMessage(SoapMessage message) throws Fault {
        message.put("org.apache.cxf.stax.force-start-document", Boolean.TRUE);        
    }

}
