The servlet forwards the processed data to the view using the __________ mechanism.
- forward
- include
- request
- response
The servlet forwards the processed data to the view using the forward mechanism, allowing the view to render the updated information based on the servlet's processing.
Servlets in an MVC framework typically receive user input through __________.
- cookies
- hidden fields
- request parameters
- session attributes
Servlets in an MVC framework typically receive user input through request parameters, which are data sent by the client as part of the HTTP request and can be accessed by the servlet.
The __________ pattern used in MVC frameworks centralizes request handling in a single servlet.
- Adapter
- Front Controller
- Observer
- Strategy
The Front Controller pattern used in MVC frameworks centralizes request handling in a single servlet.
Which component in the MVC framework is typically implemented using servlets?
- Controller
- DAO
- Model
- View
In the MVC framework, servlets are typically used to implement the Controller component, responsible for handling user input, processing requests, and interacting with the model and view components.
In an MVC-based web application, where do servlets generally fit in?
- Controller
- DAO
- Model
- View
In an MVC-based web application, servlets generally fit in the Controller layer. They handle user input, process requests, and coordinate communication between the model and view components.
How are requests forwarded from servlets to the appropriate view in an MVC framework?
- Forward
- Include
- Redirect
- Response.sendRedirect()
Requests from servlets to the appropriate view in an MVC framework are forwarded using the Forward mechanism, allowing seamless interaction between the controller and the view components.
What role do servlets play in handling controller logic in MVC frameworks?
- Servlets are responsible for rendering views in MVC frameworks.
- Servlets handle the controller logic by processing and managing user requests.
- Servlets manage database connections in MVC architectures.
- Servlets primarily focus on handling presentation logic in MVC.
Servlets play a crucial role in handling controller logic by processing and managing user requests, directing them to the appropriate components in the MVC architecture.
In MVC architecture, how does a servlet interact with the model to process business logic?
- Servlets communicate with the model through JavaBeans or other business logic components.
- Servlets directly manipulate the model by interacting with the database.
- Servlets have no interaction with the model in MVC.
- Servlets use JSPs exclusively to handle business logic in MVC.
Servlets interact with the model by communicating through JavaBeans or other dedicated business logic components to process business logic in an MVC application.
How are servlets used in conjunction with JSPs in a typical MVC application?
- Servlets and JSPs are interchangeable and can be used for any MVC role.
- Servlets and JSPs are not used together in MVC applications.
- Servlets handle business logic, and JSPs handle presentation logic.
- Servlets handle presentation logic, and JSPs handle controller logic.
In a typical MVC application, servlets are often used to handle business logic, while JSPs are used for presentation logic. Servlets and JSPs work together to achieve a separation of concerns in MVC.
How can servlets be effectively used to implement the front controller pattern in an MVC application?
- Delegate control to JSP pages
- Directly connect the servlets to the database
- Implement a central servlet that handles all incoming requests
- Use multiple servlets for each controller action
Servlets can effectively implement the front controller pattern by having a central servlet that handles all incoming requests, allowing for a centralized point to manage request handling in an MVC architecture.
