How to change Mime Headers of SOAP message using Java

I have to change Mime header for SOAP request, especially the 'content type' header, my code is already working for most of headers, but for some reason I get back the old value for the content type header:
Here is the simplified code with comments:
public static synchronized SOAPMessage sendSoapRequest(String endpointUrl, SOAPMessage request) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException {
SOAPMessage response = null;
HashMap<String,String> headers = ConfigManager.GetInstance().GetHeaders();
int number_of_retries = ConfigManager.GetInstance().GetNumberOfAttempts();
if (number_of_retries==0)
{
number_of_retries = 10;
}
for (int i = 0; i <=number_of_retries ; i++) {
try {
// Send HTTP SOAP request and get response
SOAPConnection soapConnection
= SOAPConnectionFactory.newInstance().createConnection();
***// here I have mime headers with "Content-Type: text/xml; charset=utf-8"***
if (headers != null)
{
Iterator it = headers.entrySet().iterator();
while (it.hasNext()) {
HashMap.Entry pair = (HashMap.Entry)it.next();
// request.getMimeHeaders().addHeader(pair.getKey().toString(), pair.getValue().toString());
request.getMimeHeaders().setHeader(pair.getKey().toString(), pair.getValue().toString()); ***// I set here: "Content-Type => application/soap+xml"***
}
request.saveChanges(); ***// I got back mime headers with "Content-Type: text/xml;*** charset=utf-8"
}
response = soapConnection.call(request, endpointUrl); ***// If I don't use request.saveChanges(), I also get back mime headers with "Content-Type: text/xml; charset=utf-8"***
// Close connection
soapConnection.close();
return response;
}
}
return null;
}
I don't understand why Content-Type is set back to 'text/xml; charset=utf-8' and how to fix it.

From the code you have and the comment, it seems to me that you are using SAAJ to make a SOAP call to a SOAP 1.2 endpoint and your attempt to set the correct content type is conflicting with whatever SAAJ is doing behind the scenes.
SAAJ allows you to work with an object tree while handling the SOAP details for you. By default it knows to work with SOAP 1.1. The main thing to note here is that for SOAP 1.1. the content type is text/xml and the SOAP XML namespace is http://schemas.xmlsoap.org/soap/envelope/.
You want to send application/soap+xml which is the content type for SOAP 1.2. The SOAP XML namespace will in this case be http://www.w3.org/2003/05/soap-envelope.
So even if you manage to set the desired content type, your XML message created by SAAJ will still be wrong because it will have the namespace of SOAP 1.1. because that's the default.
If you want to call a SOAP 1.2. endpoint you need to tell SAAJ that. Your SAAJ object tree is probably built by using a MessageFactory which has a default instantiation of SOAP 1.1. with:
MessageFactory mf = MessageFactory.newInstance();
If you need SOAP 1.2. you need to tell SAAJ that with this instead:
MessageFactory mf = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);
If you do that you will still have the issue with the content type, but this time it will be SAAJ setting application/soap+xml (which is what you want) and also set the proper XML SOAP namespaces within the message.

Unable to view reply in SOAP call

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

using SOAPHeader class to update SOAPMessage Header java

Scenario: I have to call a WSDL based webService and parse its response.
Problem: I am having problem to update the SOAPMessage SOAP Header & SOAP Body OR SOAP Enevelope, which I can create using the classes generated from the WSimport tool.
I have generated java classes for the provided wsdl using WSimport tool. There were many classess generated and among them I found one class which has objects to create SOAP Header, Body and other details as shown in the picture. My problem is that when I generate my soapbody and header from the provided class, I am not able to add it to the SOAP Message which i want to post to the webservice in order to get the response. Is there any method that i need to create to generate SOAP message ?
{
Body mySoapBody = new Body();
Header mySoapHeader = new Header();
Envelope mySoapEnevelope = new Envelope();
//Generate SOAP Body
mySoapBody.getAny().add(objofIdentifyCustomerClass);
//Generate SOAP Header
mySoapHeader.getAny().add(emfHeader);
//Generate SOAP Enevelope
mySoapEnevelope.setBody(mySoapBody);
mySoapEnevelope.setHeader(mySoapHeader);
//This is an Issue, Cant add generated Header to the SOAP Message
SOAPMessage soapMsg= MessageFactory.newInstance().createMessage( );
//MessageFactory factory = MessageFactory.newInstance();
//SOAPMessage message = factory.createMessage();
soapMsg.getSOAPBody().addDocument(getRE02XMLBodyMsg(ciscoRE02Request));
// How to add/update SOAP Header in the SOAPMessage ????
}

I guess I was not understanding the process correctly. I read blogs of this location which helped me resolve the problem and made the code efficient:

If you have problem writing to a WebService I highly encourage you to read this article.

HandleFault in CXF interceptors

I'm using CXf's fault out interceptor to intercept the exception from the web services method. That works fine within the handleMessage method..
Now I have two questions,
How do I had extra information to the Fault object apart from setting the faultcode?
Say if there is any error in the handleMessage method, the control goes to handleFault method but in the handle fault method it simply unwinds and logs something like - GetMth has thrown exception, unwinding now: java.lang.Exception. But the fault message(in xml format) is not being sent to the client as Output mesasage,
2. How do I make sure that the fault message is sent as SOAPfault to the clinet? (in the hanldeMessage below, i have place `f=null` to introduce the fault) Please Suggest!!!
I managed to write the xml content to the writer class with the below code, but am unable to pass this message to the client. I mean even after writing the message to the xmlwriter class and content being written fine to the console log, its not been sent to the client. i.e, I dont see the outbound message being sent nor printed when i turn on the monitors and the interceptor outbound logs. Could anyone please help me with this?
MessageFactory factory = getFactory(message);
SOAPMessage soapMessage = factory.createMessage();
SOAPPart soapPart = soapMessage.getSOAPPart();
SOAPBody soapBody = soapPart.getEnvelope().getBody();
SOAPFault soapFault = soapBody.addFault();
soapFault.setFaultString("Strange");
W3CDOMStreamWriter writer1 = new SAAJStreamWriter(soapPart);
message.setContent(XMLStreamWriter.class, writer1);
message.setContent(SOAPMessage.class, soapMessage);
message.setContent(Node.class, soapMessage.getSOAPPart());
message.getInterceptorChain().add(SAAJOutEndingInterceptor.INSTANCE);

Please advise.

JAX-WS get soap without actually sending to a web-service

Using JAX-WS and a custom WSDL, is there a way to get the message that would be sent to a web-service without actually making a call to the service? I need to generate a soap message conforming to a WSDL, but that soap message is actually embedded into another message. I was thinking I could create a local web-service that just echos back the message but it seems like there should be a way without doing this or using a handlerchain when it doens't really matter that the message is sent.
Maybe the easiest thing to do is just to generate the soap manually?

I hope this helps:
http://www.java-tips.org/java-ee-tips/java-api-for-xml-web-services/writing-a-handler-in-jax-ws.html
You can intercept message before being sent, get the body, get the header, sign it with SAML or whatever you want, and then send it to server.

maybe this example helps (from Understanding Web Services, Part 1: SOAP, IBM Developer Works, page 21):
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage message = messageFactory.createMessage();
SOAPPart SOAPPart = message.getSOAPPart();
SOAPEnvelope envelope = SOAPPart.getEnvelope();
SOAPBody body = envelope.getBody();
SOAPElement bodyElement = body.addChildElement(envelope.createName("echo", "req", "http://localhost:8080/axis2/services/MyService/"));
bodyElement.addChildElement("category").addTextNode("classifieds");
message.saveChanges();
SOAPPart SOAPpartbefore = message.getSOAPPart();
SOAPEnvelope reqenv = SOAPpartbefore.getEnvelope();
System.out.println(reqenv.toString());
