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

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

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 3

A deployment descriptor describes
A)Web component response settings
B)Web component setting
C)Web component request objects
D)All of the above

Accepted Answer

B

Question 4

The values of and in web.xml file A)must be same B)must not be same C)may be same D)None of the above

Accepted Answer

The values of and in a web.xml file may be the same, but typically they are different. The is a logical name used to reference the servlet in other parts of the web.xml, while specifies the fully qualified class name of the servlet.

A)Initialization, Cleanup, Compilation, Execution
B)Initialization, Compilation, Cleanup, Execution
C)Compilation, Initialization, Execution, Cleanup
D)Cleanup, Compilation, Initialization, Execution

Accepted Answer

The correct order of phases in the JSP life cycle is Compilation, Initialization, Execution, Cleanup.

Question 7

Which attribute specifies a JSP page that should process any exceptions thrown but not caught in the current page?
A)The ErrorPage Attribute
B)The IsErrorPage Attribute
C)Both A & B
D)None of the above

Accepted Answer

The ErrorPage attribute in JSP is used to specify a page that will handle exceptions thrown by the current page.

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 9

Which of the following is an advantage of the statement - Separation of business logic from JSP ?
A)Custom Tags in JSP
B)JSP Standard Tag Library
C)All the above
D)None of the above

Accepted Answer

The answer of Which of the following is an advantage...

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.

Question 11

JavaServer Pages often serve the same purpose as programs implemented using the Common Gateway Interface (CGI)

Accepted Answer

JavaServer Pages (JSP) and CGI programs both enable dynamic content generation for web applications, allowing server-side logic to generate HTML for client browsers.

Question 12

Which is the Microsoft solution for providing dynamic Web content?
A)ASP
B)JSP
C)Both A and B
D)None of the above

Accepted Answer

ASP (Active Server Pages) is Microsoft's server-side script engine for dynamically-generated web pages. JSP (JavaServer Pages) is a technology used for the same purpose but developed by Sun Microsystems, not Microsoft.

Question 13

Which tag is used to execute java source code in JSP?
A)Declaration Tag
B)Scriptlet tag
C)Expression tag
D)None of the above

Accepted Answer

Scriptlet tag is used to execute Java source code in JSP.

Question 14

A JSP page consists of which tags?
A)HTML tags
B)JSP tags
C)Both A & B
D)None of the above

Accepted Answer

A JSP page can contain both HTML tags and JSP tags, allowing for the creation of dynamic web content.

Question 15

Which packages does a JSP API consist of?
A)javax.servlet.jsp
B)java.servlet
C)javax.servlet.jsp.tagext
D)Both A & C

Accepted Answer

The JSP API consists of two packages: javax.servlet.jsp and javax.servlet.jsp.tagext. These packages support the development of JavaServer Pages.

Question 16

Which of the scripting of JSP not putting content into service method of the converted servlet?
A)Declarations
B)Scriptlets
C)Expressions
D)None of the above

Accepted Answer

The answer of Which of the scripting of JSP not...

Question 17

The difference between Servlets and JSP is the …………….
A)translation
B)compilation
C)syntax
D)Both A and B

Accepted Answer

The primary difference between Servlets and JSP is in their syntax. Servlets are written in Java, and their syntax is purely Java code. JSP (JavaServer Pages), on the other hand, allows for more of an HTML-like syntax with Java code embedded within it, making it more convenient for designing web pages.

Question 18

Which of the following are the valid scopes in JSP?
A)request, page, session, application
B)request, page, session, global
C)response, page, session, application
D)request, page, context, application

Accepted Answer

The valid scopes in JSP are request, page, session, and application. These scopes determine the visibility and lifetime of attributes.

Question 19

JSP includes a mechanism for defining …………………………. or custom tags.
A)static attributes
B)local attributes
C)dynamic attributes
D)global attributes

Accepted Answer

JSP includes a mechanism for defining dynamic attributes or custom tags, allowing developers to create their own tag libraries that encapsulate complex behavior.

Question 20

Why DB connections are not written directly in JSPs?
A)Response is slow
B)Not a standard J2EE architecture
C)Load Balancing is not possible
D)Both B and C

Accepted Answer

Directly writing database connections in JSPs is not considered a standard J2EE architecture practice, and it can also interfere with the implementation of effective load balancing strategies.
