Unable to display data fetched from the database - database

Question

I am new to stackoverflow and to Java. I am trying to fetch the data from the database then display it in a JSF page.
For the table I have a model : BusesInfo.java that contains getters and setters for the attributes of the table.
then I also have BusesDao that fetches the data from DB and stores it in an array list. BusesInfoBean that links these data to the JSF page. The connection to the database is success. the JSF page contains a table that calls BusesInfobean.busesInfo in the columns i call BusesInfo.attribute
Please I need your help! Below you can find sample codes:
package beans;
import daos.BusesDao;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.annotation.PostConstruct;
import javax.faces.view.ViewScoped;
import models.BusesInfo;
#ViewScoped
public class BusesInfoBean implements Serializable {
private final BusesDao busesDao = new BusesDao();
private ArrayList<BusesInfo> busesInfo;
public BusesInfoBean(){}
#PostConstruct
public void init(){
try {
busesInfo = busesDao.buildBusesInfo();
} catch (Exception ex) {
Logger.getLogger(ManageEventsBean.class.getName()).log(Level.SEVERE, null, ex);
}
}
public ArrayList<BusesInfo> getBusesInfo() {
return busesInfo;
}
public void setBusesInfo(ArrayList<BusesInfo> busesInfo) {
this.busesInfo = busesInfo;
}
}
BusesDao.java
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.HashMap;

public class BusesDao extends ConnectionDao {
public ArrayList<BusesInfo> buildBusesInfo() throws Exception {
ArrayList<BusesInfo> list = new ArrayList<>();
Connection conn = getConnection();
try {
String sql = "SELECT * FROM BUSES_INFO";
PreparedStatement ps = conn.prepareStatement(sql);
ResultSet rs = ps.executeQuery();
while (rs.next()) {
list.add(populateBusesInfo(rs));
}
rs.close();
ps.close();
return list;
} catch (SQLException e) {
throw new SQLException(e.getMessage());
}
}
private BusesInfo populateBusesInfo(ResultSet rs) throws SQLException {
BusesInfo busesInfo = new BusesInfo();
busesInfo.setBusID(rs.getInt("BUS_ID"));
busesInfo.setDriverID(rs.getInt("DRIVER_ID"));
busesInfo.setDepartureTime(rs.getString("DEPARTURE_TIME"));
busesInfo.setArrivalTime(rs.getString("ARRIVAL_TIME"));
busesInfo.setRouteEn(rs.getString("ROUTE_EN"));
busesInfo.setRouteAr(rs.getString("ROUTE_AR"));
busesInfo.setLicensePlate(rs.getString("LICENSE_PLATE"));
busesInfo.setCapacity(rs.getInt("CAPACITY"));
return busesInfo;
}
public static void main(String [] args){
try {
BusesDao busesDao = new BusesDao();
ArrayList<BusesInfo> busesInfo = busesDao.buildBusesInfo();
} catch (Exception ex) {
Logger.getLogger(EventsDao.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
the model class BusesInfo only contains getters and setters:
public class BusesInfo implements Serializable {
private int busID;
private int driverID;
private String departureTime;
private String arrivalTime;
private String routeEn;
private String routeAr;
private String licensePlate;
private int capacity;
public BusesInfo(){}

this.busID = busID;
this.driverID = driverID;
this.departureTime = departureTime;
this.arrivalTime = arrivalTime;
this.routeEn = routeEn;

this.capacity = capacity;
}
public int getBusID() {
return busID;
}
public void setBusID(int busID) {
this.busID = busID;
}
public int getDriverID() {
return driverID;
}
public void setDriverID(int driverID) {
this.driverID = driverID;
}
public String getDepartureTime() {

}
public void setDepartureTime(String departureTime) {
this.departureTime = departureTime;
}
public String getArrivalTime() {
return arrivalTime;
}
public void setArrivalTime(String arrivalTime) {
this.arrivalTime = arrivalTime;
}
public String getRouteEn() {
return routeEn;
}
public void setRouteEn(String routeEn) {
this.routeEn = routeEn;
}
public String getRouteAr() {
return routeAr;
}
public void setRouteAr(String routeAr) {
this.routeAr = routeAr;
}
public String getLicensePlate() {

}
public void setLicensePlate(String licensePlate) {
this.licensePlate = licensePlate;
}
public int getCapacity() {

}
public void setCapacity(int capacity) {
this.capacity = capacity;
}
}
