Yesterday I started upgrading a framework I maintain from Xalan 1 to
Xalan 2 (2.2.D9). Everything went just fine until I started replacing my
XSLTInputSource usage. I'm sure this is merely user error on my part,
but I'm having a hard time figuring out where the problem is.
Basically, I am trying to load the file
http://localhost:8000/servlet/ui.xsl.
Using Xalan 1 I would parse the XSL file into a DOM tree, then use the
DOM tree later to generate HTML. Loading my XSL file in Xalan 1 looked
like:
String xslFile =
event.getConfig().getServletContext().getInitParameter("xsl.document");
DOMParser parser = new DOMParser();
parser.parse(new XSLTInputSource(xslFile));
xslDocument = parser.getDocument();
Moving to Xalan 2 I now use StreamSource, Transformer, and
TransformerFactory. My code for loading the XSL file looks like:
String xslFile =
event.getConfig().getServletContext().getInitParameter("xsl.document");
TransformerFactory factory = TransformerFactory.newInstance();
transformer = factory.newTransformer(new StreamSource(xslFile));
My source code using Xalan 1 works fine, and has for about 8 months.
With Xalan 2, OTOH, I get the following error:
javax.xml.parsers.ParserConfigurationException: Namespace not supported
by SAXParser

<snip>
I am confused by the error. I think what the error is reporting is the
fact that StreamSource cannot load http: protocols. That, or I am doing
something wrong. In either case, after several hours debugging, the
clue-o-meter is still dangerously close to zero, so any help would be
appreciated. TIA.
