Hi Steve,
the DN enhancer will generate a default constructor if there is none
defined explicitly, and so I think that your ChatsParticipant is actually:
ChatsParticipant has only
public class ChatsParticipant extends Attendee {
public ChatsParticipant() {
super();
}
public ChatsParticipant(ChatsPerson person) {
super(person);
}
...
}
The error you have is:
java.lang.IllegalAccessError: tried to access method
au.com.scds.eventschedule.base.impl.Attendee.<init>()V from class
au.com.scds.chats.dom.participant.ChatsParticipant
.In this the Attendee.<init>()V is a reference to your private constructor
of Attendee.
The fix will be to change the visibility of Attendee's constructor to
protected or public.
HTH
Dan
