Subject: [xsl] Problem transforming a xml document From: Carlos Barroso <est-c-barroso@xxxxxxxxxxxxx> Date: Fri, 14 Mar 2003 10:29:04 -0000 |
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. XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
