 public void trsToXml(String ofile)
 {
  SAXTransformerFactory
factory=(SAXTransformerFactory)SAXTransformerFactory.newInstance(); //the
exception points to this line
  try{
   FileWriter fw=new FileWriter(ofile);
   PrintWriter pw=new PrintWriter(fw,true);
   StreamResult stream=new StreamResult(pw);
   handler=factory.newTransformerHandler();
   Transformer trans=handler.getTransformer();
   trans.setOutputProperty(OutputKeys.ENCODING,"ISO-8859-1");
   trans.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"trs_xml.dtd");
   trans.setOutputProperty(OutputKeys.INDENT,"yes");
   handler.setResult(stream);
   handler.startDocument();
   AttributesImpl atts=new AttributesImpl();
   handler.startElement("", "", "test", atts);
   atts.clear();
   handler.startElement("", "", "foo", atts);
   handler.characters(new char[]{'a','b','c'}, 0, 3);
   handler.endElement("", "", "foo");
   handler.endElement("", "", "test");
   handler.endDocument();
   pw.flush();
   pw.close();
  }catch(Exception _){_.printStackTrace();}
this one throws the first exception
 }
 public void xmlToTrs(File sfile,String oFileName)
 {
  PrintWriter pWriter=null;
  try{
   SAXParserFactory factory=SAXParserFactory.newInstance(); // the exception
points to this line
   factory.setValidating(true);
   SAXParser parser=factory.newSAXParser();
   boolean proceed=true;
   File trs=new File(oFileName);
   if(trs.isFile() && trs.exists())
   {
    System.out.println("the file \""+oFileName+"\" already exists\nDo you
wish to overwrite it ? Y/N\n");
    BufferedReader input=new BufferedReader(new InputStreamReader(System.in
));
    proceed=input.readLine().equalsIgnoreCase("y");
   }
   if(proceed)
   {
    parser.parse(sfile, new DefaultHandler());
    pWriter=new PrintWriter(new FileWriter(trs),true);
    pWriter.write(sHeading.toString
()+sGeneral.toString()+sItems.toString());
    pWriter.flush();
   }
  }
  catch(Exception _){_.printStackTrace();}
  finally{if(pWriter!=null) pWriter.close();}
 }
and this one the second
