ashutosh,
thanks for taking the time to reply.
I tried the test code and the resolution you had
posted but it did not make any difference.
Then i went on to try the sample code you had and
realized that i don't get the problem that was posted
as a bug. I didn't even need to call setSOAPEnvelope()
method. May be the issue is gone away in 1.2RC3.
However my problem still persists. My issue is that i
don't want to add a new element to the body but rather
i'd like to modify an existing one. See the code
below. None of the saveChanges() or setSOAPEnvelope()
or other method calls can make the modified body
persist beyon the scope of the invoke() method in the
handler:
public void invoke(MessageContext context) {
...
Node someNode =
body.getElementsByTagName("MyNodeName").item(0);
someNode.appendChild(
body.getOwnerDocument().createTextNode(
"someTextForMyNode"));
// print the body now
// the oputput includes the new text node
System.out.println(XMLUtils.ElementToString(body));
// the body shows the modification correctly here
// however after the message is forwarded to the
service
// you can no longer see the changes
