Core JSP In recent years, a large amount of software development activity has migrated from the client to the server. The client-centric model, in which a client executes complex programs to visualize and manipulate data, is no longer considered appropriate for the majority of enterprise applications.

Instead, applications are redesigned to use a web browser as a "terminal". The application itself resides on the server, formatting data for the user as web pages and processing the responses that the user fills into web forms.
