icon Problem sa servletom20.11.2007. u 17:05 - pre 200 meseci
da li neko zna sta bi mogao biti problem.....

na klik dugmeta u jsp strani treba da pozovem servlet i kad kliknem button on ga pozove (prikaze ga u adresbar liniji u browseru),ali se nista
ne desi....a trebalo bi da pozove proceduru i insertuje u bazu,a to ne uradi.
u web.xml je mapiran servlet

moze li ko pomoci....

Code:

public class NekiServlet extends HttpServlet
{

    static Logger logger = Logger.getLogger(NekiServlet.class);
    
    public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        try{
             //uradi nesto sa bazom ovde    
                         getServletContext().getRequestDispatcher("/jsp/neka_jsp_stranica.jsp").forward(request,response);

        } catch (Exception e) {
            logger.debug("SEVERE: desila se strasna greska..."+e.getMessage());
            e.printStackTrace();
            
        }
    }

    public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doGet(request, response);
        
    }
}


porbaj ovako da napises servlet, imaces neki trag u logu a na serverskoj konzoli ce ti se ispisati kompletan stack trace izuzetka.

Vidi, nisam se puno udubljivao u JSP stranu, ali evo ti par hintova:

Koristi MVC arhitekturu. Poenta je da izbegnes programiranje u JSP stranici i da servleti rade svoj posao, a jsp svoj.

Sto se tice servleta, on mora da ima doPost metodu (s obzirom da je to specificirano kao method u jsp stranici) koja treba da obradi zahtev. Tu mozes da pozoves neku svoju f-ju koja upisuje u db ili sta god vec da radi.

U principu, najbolje je da definises servlet koji uhvati zahtev, procita request parametre, eventualno napuni neki form bean (pogledaj apache commons beanutils, posto na zalost iz servleta ne postoji nacin da u cugu upumpas parametre u bean, dok u jsp to moze), odradis biznis logiku i napunis value objekat (neki bean), smestis ga u neki scope, a onda pomocu dispatcher-a, prosledis nekoj jsp strani da prikaze sta treba.
