A mortgage company is building a system that allows customers to apply for a mortgage using a
web application. A mortgage typically takes several days to process, so the customers receive
results through an email message. When a customer completes the mortgage form, the customer
must click the Submit button. When the Submit button is clicked, the application sends the
mortgage data to an external system for processing and displays a JSP indicating that the
application has been accepted. Because the company’s core business is mortgages, the
architecture must guarantee the delivery of mortgage data between the web application and the
external processing system. In this situation, which technology should the web application use to
send the mortgage data to the external processing system?
A.
a JMS queue
B.
XML over HTTP
C.
a synchronous web service
D.
an asynchronous web service
