JAXB duplicates database records in the output XML file

Question

I am trying to export a database through XML file using JAXB. But i get an XML file having my records with the @XMLElement name i gave it (SMS_Database) and also another one following it with <list/> as the RootElement name. I don't know where it's coming from. Here is the code:
import java.io.*;
import java.sql.*;
import java.util.ArrayList;
import javax.xml.bind.*;
public class Parse2Xml {
  static final String XMLBASE = "./SMS_Database.xml";
  static ArrayList<Intermed> dataList = new ArrayList<Intermed>();
  static Connection con = null;
  static PreparedStatement ps = null;
  static ResultSet rs = null;
  public static void main(String[] args) throws JAXBException, IOException {
        con = getConnection();
        try{
          ps = con.prepareStatement("SELECT * FROM SMS_Log");
          rs = ps.executeQuery();
          while (rs.next()) {
              dataList.add(getData(rs));
          rs.close();
          ps.close();
          con.close();
        } catch (SQLException ex) {
            ex.printStackTrace();
        DataStore SMS_Database = new DataStore();
        SMS_Database.setList(dataList);
        JAXBContext context = JAXBContext.newInstance(DataStore.class);
     Marshaller m = context.createMarshaller();
     m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
     Writer w = null;
     try {
          w = new FileWriter(XMLBASE);
          m.marshal(SMS_Database, w);
     } finally {
          try {
               w.close();
          } catch (Exception e) {
    static Connection getConnection(){
        String sqlURL = "jdbc:mysql://localhost:3306/SMSDB";
        String username = "SUNNYBEN";
        String password = "drowssap";
        try {
            try {
                Class.forName("com.mysql.jdbc.Driver").newInstance();
            } catch (InstantiationException ex) {
                ex.printStackTrace();
            } catch (IllegalAccessException ex) {
                ex.printStackTrace();
        } catch (ClassNotFoundException ex) {
            ex.printStackTrace();
        try {
            con = DriverManager.getConnection(sqlURL, username, password);
        } catch (SQLException ex) {
           ex.printStackTrace();
        return con;
    static Intermed getData(ResultSet rs) throws SQLException {
            Intermed mediator = new Intermed();
            mediator.setSms_id(rs.getString("sms_id"));
            mediator.setSender_id(rs.getString("sender_id"));
            mediator.setMessage(rs.getString("message"));
            mediator.setPhone_no(rs.getString("phone_no"));
            mediator.setDate_sent(rs.getString("date_sent"));
            mediator.setSchedule_date(rs.getString("schedule_date"));
            mediator.setUsername(rs.getString("username"));

            return mediator;
