So I guess...

Hello I am trying to write a Java-Program which converts a XML-file in a HTML. It should take the Transformation-file from the XML-file itself. Below find a possible XML-file: <?xml version="1.0" encoding="UTF-8"?> <!-- edited with XMLSPY v5 rel. 3 U (http://www.xmlspy.com) by Michael Herren (private) -->

At the moment, I'm using the default DOM utilities to create DOM trees and then try to translate them to strings, which I would then send. I'm trying to do this with the Transformer.transform() method, passing in a DOMSource and a StreamResult, with the StreamResult...

Hi all, I'm still somewhat new to servlet/JSP programming, but I want to my application to use the MVC model.

Hello, I hope it's okay to post to the three groups simultaneously. I've got a set of four applets, all of which use the same GUI, except for one change.
