java - 是否可以在 JAX-RPC java 客户端中访问原始 SOA/XML 消息？

Question

我正在尝试通过 JAX-RPC java 客户端访问 XML 响应。

我一直在研究 Axis 自定义处理程序，但看起来它们仅在服务端有用。

Here's some code that will give you the XML response payload back. You can either get it directly from AXIS Stub class, or from a handler that wrote it to the MessageContext. Here's the one that reads it directly:

private String getSOAPResponseXML(Object clientstub) {
    String returnValue = null;
    org.apache.axis.client.Stub stub = (org.apache.axis.client.Stub)clientstub;
    Call call = stub._getCall();
    if (call != null) {
        MessageContext ctx = call.getMessageContext();
        // If I registered a handler
        // returnValue = (String) ctx.getProperty( ClientHandler.SOAP_RESPONSE );

        // or use:
        try {
            Message msg = call.getResponseMessage();
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            // NOTE: If we never get a response (a request handler throws an uncaught error
            // this can cause a java.lang.NullPointerException
            msg.writeTo(baos);
            returnValue = baos.toString();
        } catch (java.io.IOException ex) {
            log.debug("Error in getSOAPResponseXML", ex);
        } catch (javax.xml.soap.SOAPException ex) {
            log.debug("Error in getSOAPResponseXML", ex);
        }
    }
    return returnValue;
} // getSOAPResponseXML

If you need the handler, just let me know.
