Hi,
First of all Java does not allow multiple inheritance ie u can extend from only one base class.
work around :
write two seperate java class say
1. myJavaMapping.java which extends AbstractTransformation.
2. mySaxParser.java which extends DefaultHandler
And now create an object of mySaxParser in ur myJavaMapping class(see below code).
                mySaxParser parser = new mySaxParser(out);                             //Out is the outputstream
          SAXParserFactory factory = SAXParserFactory.newInstance(); //standard class
          try
               SAXParser saxParser = factory.newSAXParser();              //standard class
               this.out = out;
               saxParser.parse(in, parser);                                                 //begin parsing                                                                               
// in is inputstream object & has input XML
          catch(Exception e)
               e.printStackTrace();
Hope it is clear,
