I'm developing a stand alone timetable scheduling system using netbeans IDE and i would like to link the output (ie a created schedule/timetable) to the web browser so that it can be viewed from there once a user logs in. Ho开发者_运维问答w should i go about it?
Write a service that both desktop and browser UIs can access the same way. Both can display the same data.
You could encapsulate the logic in a service, say ScheduleService (or TimetableService). Suppose you have the following interface definining your ScheduleService:
public interface ScheduleService {
public List<Appointment> getAppointments(Date when);
public void setAppointment(Date when, Appointment appointment);
}
Then you provide your implementation under ScheduleServiceImpl:
public class ScheduleServiceImpl implements ScheduleService {
public List<Appointment> getAppointments(Date when) {
// TODO: get list of appointments
}
public void setAppointment(Date when, Appointment appointment) {
// TODO: create appointment
}
}
In your GUI code, you would directly use your ScheduleServiceImpl, while the WebService would use a proxy method. Obviously, these proxy methods should also implement the ScheduleService
interface, but in their implementation they would delegate all calls to the real implementation.
public class ScheduleServiceWebServiceImpl implements ScheduleService {
ScheduleService realImplementation = new ScheduleServiceImpl();
public List<Appointment> getAppointments(Date when) {
return realImplementation.getAppointments(when);
}
public void setAppointment(Date when, Appointment appointment) {
realImplementation(when, appointment);
}
}
}
For the WebService part, of course, you might want to transform the output (via a JSP, or XSLT) to generate HTML or any other output format.
