Converting Stax source code with Java

I have some codes:

XMLInputFactory xif = XMLInputFactory.newInstance()
TransformerFactory tf = TransformerFactory.newInstance("org.apache.xalan.processor.TransformerFactoryImpl",null)

Transformer t = tf.newTransformer()
DOMResult result = new DOMResult()
t.transform(new StAXSource(reader),result)

This results in the following errors:

The reader object is of type com sun. org. apache. xerces. internal. impl. XMLStreamReaderImpl

Solution

So I foolishly tried the wrong thing This solves it:

System.setProperty("javax.xml.transform.TransformerFactory","com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl");
