Check if the jar file that contains the
"org.apache.xerces.parsers.SAXParser" class is on your classpath.
Kind regards,

Subject: [xsl] Problem transforming a xml document
PLEASE HELP!
I'm having problems transforming a XML file. Here is the class
source code. It's only a few lines:
//---------------------- CODE -------------------------
// ** import's **
public class GenerateHTML {
public String process(String xmlString, String xslFile) throws
TransformerConfigurationException, TransformerException, DocumentException,
SAXException {
ByteArrayOutputStream result = new ByteArrayOutputStream();
SAXReader reader = new SAXReader("org.apache.xerces.parsers.SAXParser");
Document document = reader.read(new InputSource(new
StringReader(xmlString)));
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new StreamSource(new
File(xslFile)));
DocumentSource source = new DocumentSource(document);
transformer.transform(source, new StreamResult(result));
return(result.toString());
}
}
//---------------------- END CODE -------------------------
I've tested the two parameters ("xmlString" and "xslFile") and they have the
information that I want.
I'm using this class inside a bean and every time I try to transform the
generated XML (which is valid! I tested it with XML Spy 5) it keeps giving
me the following error:
--------
javax.xml.transform.TransformerFactoryConfigurationError: Provider null
could not be instantiated: java.lang.NullPointerException
at javax.xml.transform.TransformerFactory.newInstance(Unknown
Source)
( ... )
--------
I can't figure out what the problem is!? I've never had this problem before.
Can someone help me please.
