[jdom-interest] Re: jdom 1.0 XMLOutputter -- problems

Wed May 10 14:53:05 PDT 2006

all examples I see to create XML files, like for example here..

http://www.cafeconleche.org/books/xmljava/chapters/ch14s03.html

say they are creating XML files, but they're only creating what goes 
INSIDE xml file, not actual XML file..    it says on this page:

   Let’s begin with a simple JDOM program that creates this XML document:

   <?xml version="1.0"?>
   <GREETING>Hello JDOM!</GREETING>

   Since all documents should have root elements, we’ll need to
   create the root GREETING element first, then use that element
   to create the document:

      Element root = new Element("GREETING");
      root.setText("Hello JDOM!");
      Document doc = new Document(root);

doesn't this just create what goes INSIDE xml file?  and how de we 
create xml file itself (and how do we give it a name)?

thank you..
