Question

    public void getEvent(String tableClick) {

    Events e = new Events();
    try {
        pst = conn.prepareStatement("SELECT * FROM Event WHERE eventID='"+tableClick+"' ");
        rs = pst.executeQuery();
        while(rs.next()){      
        e.setEventName(rs.getString(2));
        System.out.println(rs.getString(2));
        e.setEventDate(rs.getDate(3));
        e.setEventTime(rs.getString(4));
        e.setEventVenue(rs.getString(5));
        e.setEventDetail(rs.getString(6));
        e.setEventOpportunity(rs.getString(7));
        e.setEventMoreDetails(rs.getString(8));
        e.setEndTime(rs.getString(9));
        rs.close();
        pst.close();
       }
    } 
    catch(SQLException ex){
    ex.printStackTrace();
    } 
} //end getEvent

Whilst the System.out.println(rs.getString(2) print a value from database, I am unable to populate this information in my bean.

I am using mutators to populate the JavaBean, but when I try to use the accessors in my View class of the MVC framework, it displays null.

Here is my Call from VIEW class

Method in VIEW class

     public void changeDisplay() {
       Events e = new Events();
       evTitle.setText(""+e.getEventName());
       evWhen.setText("When: "+ e.getEventDate());
       evWhere.setText("Where: "+ e.getEventVenue());
       evDescription.setText("Description: "+ e.getEventDetail());
       evOpportunity.setText("Opporunity: "+ e.getEventOpportunity());
       evMoreDet.setText("More Details: "+ e.getEventMoreDetails());
   }

This code can’t work… Why do you have a method called getEvent with a void return type? What you want is probably something like that :

public Event getEvent(String tableClick) {
Events e = new Events();
try {
    pst = conn.prepareStatement("SELECT * FROM Event WHERE eventID='"+tableClick+"' ");
    rs = pst.executeQuery();
    while(rs.next()){      
    e.setEventName(rs.getString(2));
    System.out.println(rs.getString(2));
    e.setEventDate(rs.getDate(3));
    e.setEventTime(rs.getString(4));
    e.setEventVenue(rs.getString(5));
    e.setEventDetail(rs.getString(6));
    e.setEventOpportunity(rs.getString(7));
    e.setEventMoreDetails(rs.getString(8));
    e.setEndTime(rs.getString(9));
    rs.close();
    pst.close();
    return e;
   }
} catch(SQLException ex) {
    ex.printStackTrace();
    return null;
} 

} //end getEvent

I don’t know how your code is working but you probably want to called that method from the view and then display the value. Your changeDisplay method is displaying null because you just created the object…

You probably need something like :

public void changeDisplay(Events e) {
    evTitle.setText(""+e.getEventName());
    evWhen.setText("When: "+ e.getEventDate());
    evWhere.setText("Where: "+ e.getEventVenue());
    evDescription.setText("Description: "+ e.getEventDetail());
    evOpportunity.setText("Opporunity: "+ e.getEventOpportunity());
    evMoreDet.setText("More Details: "+ e.getEventMoreDetails());
}
