Discuss JSP design patterns.

bookmark

JSP design patterns are reusable solutions to common design problems encountered in JSP-based applications. Some commonly used design patterns in JSP include:

  • Model-View-Controller (MVC): Separates the application into model (data), view (presentation), and controller (logic) components to achieve separation of concerns.
  • Front Controller: Centralizes request handling and dispatches requests to appropriate components.
  • View Helper: Encapsulates complex view-related logic and data manipulation into a separate helper class to simplify JSP code.
  • Data Access Object (DAO): Provides an abstraction layer for accessing and manipulating data from various data sources.
  • Composite View: Combines multiple smaller views into a single cohesive view to enhance reusability and maintainability.
