public class AccountBean  {
   private Account account;

   public AccountBean() {
         account = new Account();
   }
   //setters and getters

   public void submit() {
             //persist to DB
             account = new Account();   //create a new account after
submit
    }
}

Well, taking a look at this bean notice the account = new Account()
line in the submit method.  That means that after an account is created
via the submit method the bean will hold a blank new account which will
hold no information whatsoever.   When you visit the page all the
information will be blank.   Another strategy  is to remove that
line...

public class AccountBean  {
   private Account account;

   public AccountBean() {
         account = new Account();
   }
   //setters and getters

   public void submit() {
             //persist to DB
             //account = new Account();   //this line is removed
    }
}

and just make sure that the AccountBean is of request scope and you
will get the same functionality.
