Hi again, I think I have replicated the issue that you're encountering with the code from the UserGuide. I'm currently investigating it. With regards to your 2nd questions, Cache has no getChild() method, I suppose you're refering to getNode() instead? If so, this is indentical to calling cache.getRoot().getChild(fqn). There's no difference between them two. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4240934#...
