Re-assign value tag after first form submission?

Assume I have the following class

public class Account {

  private Long id;
  private String username;
  private String password;

  // getters + constructor

}

The following action class

public MyAction extends ActionSupport {

  private CoreService service;

  private long id;
  private String username;
  private String password;

  private Account account;

  public String loadAccount() {
    account = service.getAccountById(id);
    return SUCCESS;
  }

  public String updateAccount() {
    service.updateAccount(account);
    return SUCCESS;
  }
  // getters + setters
}

I use the loadAccount() method to populate the form's fields.

And my form:

<form action="update_account" method="post">
      <label for="username">New username</label>
      <input type="text" name="username" value="${account.username}" id="username" placeholder="Enter name" required>

      <label for="password">New password</label>
      <input type="password" name="password" id="password" placeholder="Enter new password" required>
</form>

Now, assume the user will write down a new username but the validation fails. The value inside 'username' textfield will be reset to account's username. I want to change my program and make it initially load account's username but then if validation fails it will load the last input.

Change the code for displaying a field

<input type="text" name="username" value="${username}" id="username" placeholder="Enter name" required>

then a method to set it after loading

public String loadAccount() {
  account = service.getAccountById(id);
  setUsername(account.getUserName());
  return SUCCESS;
}
