Java EE (Java Enterprise Edition) General Discussion

I'm trying to create a blank XML document that will have the skeleton of a well formed XML document and a root node.

I'm doing this

DocumentImpl newdoc = new DocumentImpl();
Element faq = newdoc.createElement("faq");
newdoc.appendChild(faq);
to create the new document and make faq the root node but it does nothing. I've already created the file into which this root node should go using

PrintWriter out = new PrintWriter (new FileOutputStream("filename.xml"), true);
Is this correct?

Any help is greatly appreciated.
