Question 1

What is the difference between servlets and applets?
i. Servlets execute on Server; Applets execute on browser
ii. Servlets have no GUI; Applet has GUI
iii. Servlets creates static web pages; Applets creates dynamic web pages
iv. Servlets can handle only a single request; Applet can handle multiple requests

A)i, ii, iii are correct
B)i, ii are correct
C)i, iii are correct
D)i, ii, iii, iv are correct

i, ii are correct

Accepted Answer

i. Servlets are server-side components that run on a web server, handling requests and responses, while applets are client-side components that run within a web browser, providing a graphical user interface (GUI) for interaction.ii. Servlets typically do not have a graphical user interface (GUI) as they run on the server side and generate dynamic content, often in the form of HTML pages. Applets, on the other hand, are designed to have a GUI and run in a web browser, allowing for interactive features.iii. The statement that servlets create static web pages is incorrect; servlets are capable of creating dynamic web content based on the request they receive.iv. The statement that servlets can handle only a single request is incorrect; servlets are designed to handle multiple concurrent requests. Similarly, the statement about applets handling multiple requests is misleading in this context, as applets primarily interact with the user in the browser and any handling of "requests" would typically involve communication with a server component, not the applet directly managing these requests.

Question 2

Which are the session tracking techniques?
i. URL rewriting
ii. Using session object
iii.Using response object
iv. Using hidden fields
v. Using cookies
vi. Using servlet object

A)i, ii, iii, vi
B)i, ii, iv, v
C)i, vi, iii, v
D)i, ii, iii, v

i, ii, iv, v

Accepted Answer

Session tracking can be achieved through URL rewriting, using session objects, using hidden fields, and using cookies. These methods help maintain state between client requests in stateless HTTP protocol environments.

Question 8

The ASP and JSP technologies are quite similar in the way they support the creation of Dynamic pages, using HTML templates, scripting code and components for business logic.

Accepted Answer

Both ASP (Active Server Pages) and JSP (JavaServer Pages) are server-side technologies that allow the creation of dynamic, server-generated web pages by embedding scripts (written in VBScript or JavaScript for ASP and Java for JSP) within HTML to manage the content dynamically. They support the use of components or objects for implementing business logic, thus making them similar in their approach to generating dynamic web content.

Question 10

JSPs eventually are compiled into Java servlets, you can do as much with JSPs as you can do with Java servlets.

Accepted Answer

JSPs (JavaServer Pages) are indeed compiled into Java servlets by the server. Since servlets are Java classes that handle requests and responses in a web application, and JSPs are essentially a more convenient way to write servlets (allowing for easier inclusion of HTML and other content), anything you can do with a servlet can also be achieved with a JSP, albeit with potentially different syntax and structure.
