> If the "resultset" is not iterated completely ,  one filehandler is leaking
> Ex: We need only first row. This case one resource is leaking
> {code}
> ResultSet resultSet = createStatement.executeQuery("select * from sampletable");
> if (resultSet.next())
> {
> 	System.out.println(resultSet.getString(1)+"   "+resultSet.getString(2));
> } 
> {code}
> Command used for checking the filehandlers
> {code}
