无法在SOAP调用中查看回复

Question

I'm currently working on a custom SOAP call to a specific domain beyond my control. I know the SOAP call fails but I cannot seem to grab the returned (wrong)value.

Right now I'm using the code below:

                    Document document = convertStringToDocument(this.MeldingString);
                // System.out.println(document);
                SOAPConnectionFactory myFct = SOAPConnectionFactory.newInstance();
                MessageFactory myMsgFct = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);
                SOAPMessage message = myMsgFct.createMessage();
                SOAPConnection myCon = myFct.createConnection();

                // Adding parts
                SOAPPart mySPart = message.getSOAPPart();
                SOAPEnvelope myEnvp = mySPart.getEnvelope();

                // Escape the password for usage in header
                String escpwd = StringEscapeUtils.escapeJava(this.Password);

                // Header
                MimeHeaders headers = message.getMimeHeaders();
                headers.setHeader("Content-Type", "application/soap+xml;charset=UTF-8");
                headers.setHeader("Authorization", this.Username + ":" + escpwd);

                // Body
                SOAPBody body = myEnvp.getBody();
                body.addDocument(document);

                // Sending
                Core.getLogger("GetResultSOAPmsg").trace("Started");
                URL endPt = new URL(
                        "URL-TO-MY-SERVICE");
                System.setProperty("java.net.useSystemProxies", "true");
                try {
                    SOAPMessage reply = myCon.call(message, endPt); "UTF-8");

            }
            catch(Exception e)
            {
                e.printStackTrace();
            }

This yields the following error which is very common al throughout SO:

SEVERE: SAAJ0537: Invalid Content-Type. Could be an error message instead of a SOAP message
com.sun.xml.internal.messaging.saaj.SOAPExceptionImpl: com.sun.xml.internal.messaging.saaj.SOAPExceptionImpl: Invalid Content-Type:text/html. Is this an error message instead of a SOAP response?

Now I have read most of these topics already and they explain how this problem is usually solved (namespaces, escaping URL, etc.) but I cannot seem to figure out what is wrong in my case. This is a private service and the other side is unfortunately unable to assist me in this case. The error could be anything from wrong certificates to misspelling the URL.

Therefore I would like to actually SEE onscreen what the actual reply is that was received when making the call. This is going to help me (assuming it's something like a 503, 404 or other page). Regardless of what I do and where I set my breakpoints, there is no information on Reply. It makes somewhat sense since it was unable to create said object but the entire message seems to be discarded.

In what way will I be able to see what the actual reply was to my call before it is discarded?

I think there's a problem with your header

headers.setHeader("Content-Type", "application/soap+xml;charset=UTF-8");

try something like

headers.setHeader("Content-Type", "application/xml;charset=UTF-8");

or

headers.setHeader("Content-Type", "application/json;charset=UTF-8");

depending on the content type that the content type accepted by the service
