I have seen this question asked before, but with no definitive answer.
I have a handler which needs to modify a message. After some experimentation, I tried the following:
1 Message message = (Message) messageContext.getCurrentMessage();
2 SOAPBody soapBody = (SOAPBody) message.getSOAPEnvelope().getBody();
3 SOAPEnvelope soapEnvelope = new SOAPEnvelope();
4 Iterator iterator = soapBody.getChildElements();
5 while (iterator.hasNext()) {
6 SOAPBodyElement soapBodyElement = (SOAPBodyElement) iterator.next();
7 Element element = soapBodyElement.getAsDOM();
8 NodeList nodeList = element.getElementsByTagName("myTag");
9 if (nodeList.getLength() > 0) {
10 Node node = nodeList.item(0);
11 node.getFirstChild().setNodeValue("myNewValue");
12 }
13 soapEnvelope.addBodyElement(new SOAPBodyElement(element));
14 }
15 Message newMessage = new Message(soapEnvelope);
16 newMessage.setMessageContext(messageContext);
17 messageContext.setCurrentMessage(newMessage);
However, this results in an exception ("No deserialization context to use in MessageElement.getValueAsType()!", which I find from looking at the source code for Message element is because I did not set a DeserializationContext when I created a SOAPBodyElement in line 13.
What I can't figure out is how to create a DeserializationContext. The constructors for DeserializationContextImpl require either an InputSource or a SOAPHandler, and it is not clear to me how to get these.
Can anyone help, or is there a better way to get modify the message in a handler?
