I'm using Spring 3.0.2 and I have a class called MovieDAO that uses JDBC to handle the db. I have set the @Repository annotations and I want to convert the SQLException to the Spring's DataAccessException I have the following example:

   @Repository
    public class JDBCCommentDAO implements CommentDAO {

        static JDBCCommentDAO instance;
        ConnectionManager connectionManager;

        private JDBCCommentDAO() {
            connectionManager = new ConnectionManager("org.postgresql.Driver", "postgres", "postgres");
        }

        static public synchronized JDBCCommentDAO getInstance() {
            if (instance == null)
                instance = new JDBCCommentDAO();
            return instance;
        }

        @Override
        public Collection<Comment> getComments(User user) throws DAOException {
            Collection<Comment> comments = new ArrayList<Comment>();
            try {
                String query = "SELECT * FROM Comments WHERE Comments.userId = ?";
                Connection conn = connectionManager.getConnection();
                PreparedStatement stmt = conn.prepareStatement(query);
                stmt = conn.prepareStatement(query);
                stmt.setInt(1, user.getId());
                ResultSet result = stmt.executeQuery();
                while (result.next()) {
                    Movie movie = JDBCMovieDAO.getInstance().getLightMovie(result.getInt("movie"));
                    comments.add(new Comment(result.getString("text"), result.getInt("score"), user, result.getDate("date"), movie));
                }
                connectionManager.closeConnection(conn);
            } catch (SQLException e) {
                e.printStackTrace();
                        //CONVERT TO DATAACCESSEXCEPTION
            }
            return comments;
        }
}

I Don't know how to get the Translator and I don't want to extends any Spring class, because that is why I'm using the @Repository annotation
