@WebServlet annotation for JSP files

New to jsp and servlets in general. I've learned that I can skip url-mapping in web.xml by applying a @WebServlet annotation to a servlet. Its also my understanding that what a jsp file is, is something that is compiled down to a servlet at execution time. Is it possible to also apply an @Webservlet annotation to a jsp file, such that the resultant servlet is already mapped, and I don't have to create url-mapping tags in web.xml for all my .jsp files?

Thanks for any info!

Annotation @Webservlet can be applied only to Servlet(java class). If you want to get access to jsp, it's can be reach by two way:

  1. Register jsp in web.xml
  2. Create servlet with will redirect to jsp.

But add business logic to jsp is a bad practice. JSP responsible only for view part of MVC pattern.

Model-View-Controller (MVC) is a pattern used in software engineering to separate the application logic from the user interface. As the name implies, the MVC pattern has three layers.

Model Layer

This is the data layer which contains business logic of the system, and also represents the state of the application

The Controller Layer

Controller layer acts as an interface between View and Model. It receives requests from the View layer and processes them, including the necessary validations.

The View Layer

This layer represents the output of the application, usually some form of UI. The presentation layer is used to display the Model data fetched by the Controller.
