How to hide implementation of JDBC while processing large query in client's code?

I have client's methods that processes a large SQL query. I wouldn't like to do that through getting whole query result to memory, but process it in batches. It entails with exposing JDBC API to client's code. I think that this code could be refactored much better.

    //client's method
    m_jdbcManager = JdbcManagerUtil.getInstance();
    m_tupleManager = DbTupleManager.getInstance();
    Connection connection = null;
    PreparedStatement statement = null;
    ResultSet resultSet = null;
    try {
        connection = m_jdbcManager.getConnection();
        connection.setAutoCommit(false);
        statement = connection
                .prepareStatement(Statements.SELECT_RIGHT_TUPLES);
        statement.setInt(1, id);
        statement.setFetchSize(JdbcManagerUtil.FETCH_SIZE);
        resultSet = statement.executeQuery();
        while (resultSet.next()) {
            Tuple tuple = (Tuple) m_tupleManager
                    .readObject(resultSet);
            //process tuple, invokes methods from client class 
        }
        connection.setAutoCommit(true);
        JdbcManagerUtil.closeEverything(connection, statement, resultSet); 
    } catch (<exceptions>) { 
    }

I tried to expose method that returns ResultSet, but after processing, there must be released resources Connection, PreparedStatement and ResultSet. JDBC 4 and PostreSQL database.
