Spring Web with AJAX
The topic of this chapter is not a subject in the certification exam, but it is useful to know all the tools that can be used to develop a web application in the most efficient way. A properly designed user interface should ensure that a request is sent to the server only when the content of the request is complete and valid so that it can be used by a server operation. Using requests between the client and the server application is not a good practice. It is time-consuming and can go wrong when the network connection is unstable.
