Problems with insert data into a CLOB column in Oracle

I want to insert data (which is kept in a Reader variable) into a CLOB column in Oracle 9i database but it does not work. When I for example try with the code written below a row is created in the table and the column ID (just a NUMBER column) gets its value but the CLOB column remains empty (and I know there is a value in the Reader variable). Which is the best way to solve this (answers both in Danish and English is OK)??


  public void executeInsertClob(Reader inReader)
  {
  try {
      CallableStatement cs = null;
      con.setAutoCommit(false);
      // Call Stored DB procedure for updating clob column
      cs = (CallableStatement)
      con.prepareCall( "begin INSERT INTO TEST (XML,ID) VALUES (?,?); end;" );
      // use setCharacterStream to set the clob parameter.
      cs.setCharacterStream(1,inReader,6000);
      int id=99;
      cs.setInt(2,id );
      cs.execute();
      con.setAutoCommit(true);
    }catch(SQLException sqlEx)
    {
      sqlEx.printStackTrace();
      log = new Log();
      log.setLogMessage(sqlEx.getMessage());
      log.writeLogFile();
    }
 
  }
