SOAP前缀soapenv已经绑定到超文本传输协议：//

Question

我正在尝试向SOAP请求添加自定义命名空间声明，更具体地说：

env.addNamespaceDeclaration("soapenv", "http://www.w3.org/2003/05/soap-envelope");

我在SOAP消息处理程序中执行此操作，根据我使用的Web服务的规范，此命名空间声明是绝对必需的。但是，jax ws库似乎总是在发送消息之前尝试添加此soapenv命名空间声明，然后失败如下：

Exception in thread "main" javax.xml.ws.WebServiceException: javax.xml.stream.XMLStreamException: prefix soapenv has been already bound to http://www.w3.org/2003/05/soap-envelope. Rebinding it to http://schemas.xmlsoap.org/soap/envelope/ is an error

HandleMessage函数：

public boolean handleMessage(SOAPMessageContext context) {

    //Inquire incoming or outgoing message.
    boolean outbound = (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);

    try {

        if (outbound) {
            // OUTBOUND

            System.out.println("Direction=outbound (handleMessage)");
            SOAPMessage msg = ((SOAPMessageContext) context).getMessage();

            // get SOAP-Part
            SOAPPart sp = msg.getSOAPPart();

            //edit Envelope
            SOAPEnvelope env = sp.getEnvelope();
            env.addNamespaceDeclaration("web", "http://example.com/webservices");
            env.addNamespaceDeclaration("soapenv", "http://www.w3.org/2003/05/soap-envelope");
            env.removeNamespaceDeclaration("S");

            env.setPrefix("soapenv");


            SOAPHeader soapHeader = env.addHeader();
            SOAPBody soapBody = env.getBody();

            soapHeader.setPrefix("soapenv");
            soapBody.setPrefix("soapenv");

            Name ticketHeaderName = env.createName("TicketHeader", "web",
                   "http://example.com/webservices");
            SOAPElement ticketHeader =  soapHeader.addChildElement(ticketHeaderName);

            SOAPElement soapHeaderElem2 = ticketHeader.addChildElement("SessionId", "web");
            soapHeaderElem2.addTextNode(sessionId);

            msg.saveChanges();

            // print SOAP-Message
            dumpSOAPMessage(msg);

        } else {
            // INBOUND

            System.out.println("Direction=inbound (handleMessage)");
            SOAPMessage msg = ((SOAPMessageContext) context).getMessage();
            dumpSOAPMessage(msg);
         }

    } catch (Exception e) {

        //All other unhandled problems.
        e.printStackTrace();
    }
    return true;
}

使用SOAP1.1规范时会发生此错误

 <soapenv:Envelope xmlns:SOAPENV="http://schemas.xmlsoap.org/soap/envelope/"  xmlns:web="http://saxobank.com/webservices/">

但是您尝试将名称空间设置为SOAP 1.2版本：

 <soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope"  xmlns:web="http://saxobank.com/webservices/">

编写正确规格的请求为我解决了这个问题。
