How to convert SOAPBody to String

Question

I want to convert SOAPBody to String. What is the best way to do it? Should i first convert it to xml and then convert it into String or we can jsut convert it into String.<

When starting from a SOAPMessage, the easiest way is to use the writeTo method :

ByteArrayOutputStream stream = new ByteArrayOutputStream();
soapMessage.writeTo(stream);
String message = new String(stream.toByteArray(), "utf-8") 

(Above, I assume your SAAJ implementation will use UTF-8, you'd probably want to check).

If starting from a SOAPBody, then you probably should use XML APIs, seeing SOAPBody is a org.w3.dom.Element, the easiest way would probably be using TrAX :

SOAPBody element = ... // Whatever
DOMSource source = new DOMSource(element);
StringWriter stringResult = new StringWriter();
TransformerFactory.newInstance().newTransformer().transform(source, new StreamResult(stringResult));
String message = stringResult.toString();

(Sorry I do not have my IDE right here, can not check if this compiles, but that should be pretty close).

Please note : A serialized SOAPMessage may not be raw XML : it might be a MIME structure : if the SOAPMessage actually uses SwA (SOAP With Attachment) or MTOM. However, SOAPBody is definitely pure XML.
