Java - Consume SOAP Web Service from String XML Envelope
Question
Using SoapUI I have built the following XML envelope and encapsulated it in a String.
ProcessJournal is a method which has no parameters, and returns a string.
String soapText = "<Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:upd=\"http://webservices.vm.vmc/UpdateCMA/\">" +
"<Header/>" +
"<Body>" +
"<upd:ProcessJournal/>" +
"</Body>" +
"</Envelope>";
Now... I simply want to invoke the web service defined above. And have found some sample code to do so
// Create SoapMessage
MessageFactory msgFactory = MessageFactory.newInstance();
SOAPMessage message = msgFactory.createMessage();
SOAPPart soapPart = message.getSOAPPart();
// Load the SOAP text into a stream source
byte[] buffer = soapText.getBytes();
ByteArrayInputStream stream = new ByteArrayInputStream(buffer);
StreamSource source = new StreamSource(stream);
// Set contents of message
soapPart.setContent(source);
// -- DONE
message.writeTo(System.out);
//Try accessing the SOAPBody
SOAPBody soapBody = message.getSOAPBody();
The problem is, at message.getSOAPBody();, I get an error
XML-22103: (Fatal Error) DOMResult can not be this kind of node.

SEVERE: SAAJ0511: Unable to create envelope from given source
All the various samples I find, end up having the same type of error when getSOAPBody() is executed.

I don't know whether you ever found a solution to this. I've just recently been seeing the exact same error and it was due to a TransformerFactory not being set.
I used the TransformerFactory from the Saxon library - the jar for which can be obtained here .
I then set a system property which referenced the Saxon TransformerFactory:
System.setProperty("javax.xml.transform.TransformerFactory",
"net.sf.saxon.TransformerFactoryImpl");
The error then disappeared when I re-ran my code.
The above is just one way to set the TransformerFactory. There are a number of other ways to do this which I found here: stackoverflow.com/questions/11314604/

It looks like the problem was with the namespace prefixing in your soapText. I was able to execute your example without error and without manually setting any TransformerFactory simply by modifying your soapText as follows:
String soapText =
"<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:upd=\"http://webservices.vm.vmc/UpdateCMA/\">" +
"<soapenv:Header/>" +
"<soapenv:Body>" +
"<upd:ProcessJournal/>" +
"</soapenv:Body>" +
"</soapenv:Envelope>";
Note the added soapenv: prefix in all the Soap elements in contrast to the upd prefix in your Soap service namespace.
