Java/Oracle CLOB i UFT-8 format

We have data in an Oracle CLOB column in UTF-8 format. We want to write this data into a text file by using a JAVA client and keep it in UTF-8 format. To write the data into the file is no problem but we loose the UTF-8 format. How should we do to keep the UTF-8 format? A code example to solve this would be great!


    OracleResultSet orabatchResult = dbFacade.executeFetchXML();
    while (orabatchResult.next()){
        oracle.sql.CLOB clb = orabatchResult.getCLOB(1);
       
        java.io.Reader reader = clb.getCharacterStream();

        FileWriter fw=new FileWriter("test.xml");       
        int tmp;
        while ( (tmp=reader.read()) != -1 )
        {
          // Write one character at a time to the file.
          fw.write( (char) tmp );
        }
        fw.close();
    }
