Rendering HTML with a servlet

public void doGet(HttpServletRequest request,

HttpServletResponse response)

throws ServletException, IOException {

HttpSession session = request.getSession(false);

BankAccount account =

(BankAccount)session.getValue("home.banking.account");

double balance = account.getBalance();

java.text.NumberFormat number =

java.text.NumberFormat.getCurrencyInstance(Locale.UK);

String formattedBalance = number.format(balance);

//…etc.

• Following a successful look up, this servlet pulls the account object from the session, retrieves its balance and formats it using a currency object
