Help!xml can't transform property

Question

I want to transform xml using xslt and I download jakarta's xalan.But I find it seems has some problem.So I write a class to test the xalan package.My code is:
/////////////////////////////////Test30.java///////////////////////////////////////
import org.apache.xalan.xslt.XSLTProcessor;
import org.apache.xalan.xslt.XSLTResultTarget;
import org.apache.xalan.xslt.XSLTInputSource;
import org.apache.xalan.xslt.XSLTProcessorFactory;
//import com.lotus.xsl.*;
import org.xml.sax.SAXException;
import java.io.*;
import org.xml.sax.*;
10 public class Test30
11 {
12     public static void main(String[] args)
13     {
14          try
15          {
16          XSLTInputSource inputXML = new XSLTInputSource("trying1.xml");
17          XSLTInputSource inputXSL = new XSLTInputSource("trying.xsl");
18          XSLTProcessor processor = XSLTProcessorFactory.getProcessor();
19          processor.process(inputXML, inputXSL, new XSLTResultTarget(System.out));
20          }catch(Exception e)
21          {
22               System.out.println(e);
23          }
It is compiled successfully.But the console report error when I execute it.It report:"Exception in thread "main" java.lang.NoSuchFieldError: m_elemStack

I test it in servlet and the problem is the same as this.
I don't know why this happen and I debug it all day.I can't find any error today.
Anyone can help me? :(

I used this example and it works fine for me :
public static void transformXML(String xml, String xsl, OutputStream oStream)throws Exception {
TransformerFactory tFactory = TransformerFactory.newInstance();
if(tFactory.getFeature(DOMSource.FEATURE) && tFactory.getFeature(DOMResult.FEATURE)) {
//Instantiate a DocumentBuilderFactory.
DocumentBuilderFactory dFactory = DocumentBuilderFactory.newInstance();
// And setNamespaceAware, which is required when parsing xsl files
dFactory.setNamespaceAware(true);
//Use the DocumentBuilderFactory to create a DocumentBuilder.
DocumentBuilder dBuilder = dFactory.newDocumentBuilder();
//Use the DocumentBuilder to parse the XSL stylesheet.
Document xslDoc = dBuilder.parse(xsl);
// Use the DOM Document to define a DOMSource object.
DOMSource xslDomSource = new DOMSource(xslDoc);
// Set the systemId: note this is actually a URL, not a local filename
xslDomSource.setSystemId(xsl);
// Process the stylesheet DOMSource and generate a Transformer.
Transformer transformer = tFactory.newTransformer(xslDomSource);
//Use the DocumentBuilder to parse the XML input.
Document xmlDoc = dBuilder.parse(xml);
// Use the DOM Document to define a DOMSource object.
DOMSource xmlDomSource = new DOMSource(xmlDoc);
// Set the base URI for the DOMSource so any relative URIs it contains can
// be resolved.
xmlDomSource.setSystemId(xml);
// Create an empty DOMResult for the Result.
DOMResult domResult = new DOMResult();
// Perform the transformation, placing the output in the DOMResult.
transformer.transform(xmlDomSource, domResult);
//Instantiate an Xalan XML serializer and use it to serialize the output DOM to System.out
// using a default output format.
Serializer serializer = SerializerFactory.getSerializer(OutputProperties.getDefaultMethodProperties("xml"));
serializer.setOutputStream(oStream);
serializer.asDOMSerializer().serialize(domResult.getNode());
} else {
throw new org.xml.sax.SAXNotSupportedException("DOM node processing not supported!");
}
