XSLT Implementations in JDK

This section describes the Java implementation classes of XSLT in JDK. XSLT interfaces are defined in the javax.xml.transform package: TransformerFactory, Transformer, Source, Result. JDK 1.4 actually uses org.apache.xalan package for XSLT transformation.

JDK offers the following interfaces to support XSLT:

One thing seems to be missing here: who represents the transformation stylesheet? The answer is that the stylesheet will be read in when you instantiate a Transformer object.

I have a simple test program here, XSLClassChecker.java, to show what are the XSLT implementation classes included in JDK:

/* XSLClassChecker.java

import javax.xml.transform.Source;
import javax.xml.transform.Result;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.stream.StreamResult;
class XSLClassChecker {
   public static void main(String[] args) {
      try {
         TransformerFactory f = TransformerFactory.newInstance();
         System.out.println(f.toString());
         Transformer t = f.newTransformer();
         System.out.println(t.toString());
         Source s = new StreamSource();
         System.out.println(s.toString());
         Result r = new StreamResult();
         System.out.println(r.toString());
         t.transform(s,r);
      } catch (TransformerConfigurationException e) {
         System.out.println(e.toString());   
      } catch (TransformerException e) {
         System.out.println(e.toString());   
      }
   }
}

Compile and run this example program with JDK (Java Development Kit):

herong> java XSLClassChecker

com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImp...
com.sun.org.apache.xalan.internal.xsltc.trax.TransformerImpl@25154f
javax.xml.transform.stream.StreamSource@10dea4e
javax.xml.transform.stream.StreamResult@647e05
javax.xml.transform.TransformerException: Result object passed to
  ''{0}'' is invalid.
