Drop-down menu for customer login

The CustomerManager class contains a getCustomerSelectList method that retrieves the ssn of all the customers. This list can be used to populate a drop-down menu for customer login:

Open the logon.jsp.

Replace the input field with a Combo Box component:

Id: ssn1
Value: #{sessionScope.SSN}

Add two choices for the list:

Click Add Choice (Label: Select an ssn, Value: 000-00-0000)
Click Add Set of Choices (Label: <selectitems>, Value: click and locate #{customerManager.customerSelectList})

Validation: Select Value is required.
