You have taken over an old web application that contains a servlet for each use case. These servlets have become difficult to maintain because the service methods have grown big. Also,since the use cases are similar, lot of code has been repeated accross the servlets.
Which patterns can you apply in this situation?
a Business Delegate
b Transfer Object
c Front Controller
d Session Facade
e Model View Controller
the answer is given as a and c, but i feel it is c and e.
can anyone clarify?
