10.5.3 Servlet admin.java
Acest servlet este apelat atunci cand utilizatorul are rolul de administrator. Sarcina sa este de a furniza trei butoane de optiuni pentru a se lucra asupra produselor din baza de date, asupra subcategoriilor sau asupra comenziilor. Servlet-urile catre care pointeaza aceste butoane sunt: comen.java, opert.java si categ.java.
