encoding and saxparser 2003-01-20 - By Joseph Shraibman
OK here is what I used to test:

sp.setFeature("http://apache.org/xml/features/allow-java-encodings",true);
sp.setContentHandler(tch);
InputSource is = null;

{
File file = new java.io.File("/tmp/temp1.xml");
DOMParser _dp = new DOMParser();
InputStream is = new FileInputStream(file);
_dp.parse(new InputSource(is));
Document doc = _dp.getDocument() ;
StringWriter sw = new StringWriter();
TransformerFactory.newInstance().newTransformer().transform(new
DOMSource(doc), new StreamResult(sw));
%> xml: <br> <%= sw %><br>

my xml file:
<?xml version="1.0" encoding="ISO-8859-1"?>
<data>
<firstname>D�cio</firstname>
</data>
My xerces is 2.2.1. In my test the first one does not work but the last one
does.
You can see what the jsp looks like at http://xis.xtenit.com/temp.jsp (except
that has an
old version of TestContentHandler that puts colons in the output.
