Why would you design a J2EE application so user data is entered by way of a JavaServer Page and managed by an underlying JavaBeans class?
-
To make the user interface more interesting.
-
To simplify application deployment.
-
To prevent malicious programs from gaining access to sensitive information on your database server.
-
To make the application much easier to update, maintain, and manage.
The JSP-JavaBean separation follows the Model-View-Controller pattern. JSP handles presentation (the View), while JavaBeans encapsulate business logic and data (the Model). This separation means you can modify the user interface without touching business logic, and vice versa, making the application easier to update and maintain. Option A is incorrect because JSP is not about visual appeal but separation of concerns. Option C incorrectly suggests this prevents malicious programs - security requires separate measures. Option B is wrong - J2EE apps require deployment regardless of architecture.
Splitting a J2EE application into a JavaServer Page (presentation/view) backed by an underlying JavaBean (data/logic) follows the MVC-style separation of concerns — this makes the application much easier to update, maintain, and manage, because the view and the data-handling logic can change independently without breaking each other. It's not primarily about making the UI 'more interesting' (that's a design/UX concern, not an architectural reason) or simplifying deployment (JavaBeans don't inherently reduce deployment complexity) or blocking malicious access (that's a security/authorization concern handled elsewhere, not the point of this pattern).
