get/setTextContent has recently been implemented in NodeImpl. Something else is simply not implemented yet. Feel free to create a jira issue for this and link that here (btw this is an easy chance for contributing adding a small patch ;-) ).
Glad to finally get a reply, thanks! I did create a JIRA issue: https://jira.jboss.org/jira/browse/JBWS-2700. A link from the issue to this forum was already made. I did make changes to our SW or other 3rd party package locally to work with JBoss; but the solution was not pretty and I don't want to maintain other 3rd party code:-).
I am facing the same issue. Will you please help me to solve this issue.
Note: I have posted this issue in the following link.
