HTML을 파싱하는 과정에서 HTMLCLEANER를 이용해서 XML로
바꾼 다음의 코드인  strstream 를 외부 파일로 만들고 싶어서
예전 자바 시간의 배운 내용을 토대로
   String fileName = "C:\\a.txt";
   FileOutputStream fos  = new FileOutputStream(fileName);
   byte [] data = strstream.getBytes();
   fos.write(data);
   fos.flush();
   fos.close();
이렇게 구현을 했는데...파일이 안생기네요..-0-;;;
저의 잘못된 부분을 꼬집어 주시면 감사하겠습니다..ㅜㅜ
