Xalan (XML + XSL) Transformation

  Asked By: Matilda    Date: Oct 30    Category: Java    Views: 1383
  

Please, what is wrong in this code?

It is a class to transform a XML file using a XSLT file.
It just works with the simple example of Apache Xalan.
With other files, I get this message:

javax.xml.transform.TransformerConfigurationException:
javax.xml.transform.TransformerException: java.lang.ClassCastException

I use Java 1.4.02, Apache Xalan 2.5.2 and Apache Xerces 2.6.0.

// Create a transform factory instance.

InputStream xslIS = new BufferedInputStream(new
FileInputStream(psArquivoXSL));
StreamSource xslSource = new StreamSource(xslIS);
// Note that if we don't do this, relative URLs can not be
resolved correctly!
xslSource.setSystemId(psArquivoXSL);

// Create a transformer for the stylesheet.
Transformer transformer = tfactory.newTransformer(xslSource);

InputStream xmlIS = new BufferedInputStream(new
FileInputStream(psArquivoXML));
StreamSource xmlSource = new StreamSource(xmlIS);
// Note that if we don't do this, relative URLs can not be

xmlSource.setSystemId(psArquivoXML);

// Transform the source XML to System.out.
transformer.transform( xmlSource, new StreamResult(new
OutputStreamWriter(System.out)));
}
}
