Example thin client - home banking

• This example shows how HTML forms and servlets can provide a thin client architecture

• A simple form

  • gets the password and PIN from an account holder
  • posts the data to a servlet

• The first servlet (‘ProcessRequestServlet’)

  • attempts to retrieve an account from the host
  • calls other servlets to respond with the balance (if the account is retrieved) or an error page (if it is not)

• The other servlets

  • dynamically render HTML on the client
