This document provides an overview of core web application development using servlets and JSPs. It discusses what servlets and JSPs are, their lifecycles, how they interact with clients, and why they are useful for enterprise application development. Servlets are Java programs that handle requests and responses, while JSPs make it easier for designers and developers to work together by separating template data from dynamic content generation code. The document outlines the initialization, execution, and destruction phases of the servlet and JSP lifecycles, and how JSPs are translated into servlets. It also covers request parameters, sessions, JSP elements like directives and scripting tags, implicit objects, and variable scopes in J
Servlet is java class which extends the functionality of web server by dynamically generating web pages.
Servlet technology is used to create Dynamic web application. Servlet technology is robust and scalable. init() and service() methods are more important in life cycle of a servlet. doGet() and doPost() are methods used under service() method.
Servlet architecture comes under a java programming language used to create dynamic web applications. Mainly servlets are used to develop server-side applications. Servlets are very robust and scalable. Before introducing servlets, CGI (common gateway interface) was used.
A self motivated mobile application ready for integration with any brokerage company.
Application is being designed as generic as possible to ease real integration with companies and with stock organizations

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

5. What is Java Servlet?
• An alternate form of server-side computation that
uses Java
• The Web server is extended to support an API, and
then Java programs use the API to create dynamic
web pages
• Using Java servlets provides a platform-independent
replacement for CGI scripts.
• Servlets can be embedded in many different servers
because the servlet API, which you use to write
servlets, assumes nothing about the server's
environment or protocol.
6. Servlet Life Cycle
• Initialization
– the servlet engine loads the servlet’s *.class file in the JVM
memory space and initializes any objects
• Execution
– when a servlet request is made,
• a ServletRequest object is sent with all information about the
request
• a ServletResponse object is used to return the response
• Destruction
– the servlet cleans up allocated resources and shuts down
7. Client Interaction
• When a servlet accepts a call from a client,
it receives two objects:
– A ServletRequest, which encapsulates the
communication from the client to the server.
– A ServletResponse, which encapsulates the
communication from the servlet back to the
client.
• ServletRequest and ServletResponse are
interfaces defined by the javax.servlet
package.
11. Session Capabilities
• Session tracking is a mechanism that servlets use to
maintain state about a series of requests from the
same user(that is, requests originating from the
same browser) across some period of time.
• Session tracking capabilities. The servlet writer can
use these APIs to maintain state between the servlet
and the client that persists across multiple
connections during some time period.
14. What is JSP?
• A Java Servlet is a Java program that is run on the
server
– There are Java classes for retrieving HTTP requests and
returning HTTP responses
– Must return an entire HTML page, so all tuning of the page
must be done in a Java program that needs to be re-
compiled
• Java Server Pages (JSP)
– use HTML and XML tags to design the page and JSP scriplet
tags to generate dynamic content (Easier for separation
between designer & developer)
– use Java Beans and useful built-in objects for more
convenience
15. JSP Life Cycle
• JSP page (MyFirstJSP.jsp)
– Translated to Servle (MyFirstJSP.servlet)
– Compiled to class (MyFirstJSP.class)
– Loaded into memory (Initialization)
– Execution (repeats)
– Destruction
• Any change in JSP page automatically repeats the
whole life cycle.
16. Introduction
• A Java Servlet is a Java program that is run on the
server
– There are Java classes for retrieving HTTP requests and
returning HTTP responses
• Java Server Pages (JSP)
– use HTML and XML tags to design the page and JSP scriplet
tags to generate dynamic content
– use Java Beans, which are reusable components that are
invoked by scriplets
17. What do JSPs contain?
• Template data
– Everything other than elements (eg. Html tags)
• Elements
– based on XML syntax
• <somejsptag attribute name=“atrribute value”> BODY
</somejsptag>
– Directives
– Scripting
• Declarations
• Scriptles
• Expressions
– Standard Actions
18. Directives
• <%@ directivename attribute=“value”
attribute=“value” %>
• The page directive
– <%@ page ATTRIBUTES %>
– language, import, Buffer, errorPage,…
– <%@ page languange=“java”
import=“java.rmi.*,java.util.*” %>
• The include directive
– <%@ include file=“Filename” %>
– the static file name to include (included at translation
time)
• The taglib directive
– <% taglib uri=“taglibraryURI” prefix=“tagPrefix” %>
19. Scripting
(Declaration, Expressions, Scriptlets)
• <%! . . %> declares variables or methods
– define class-wide variables
– <%! int i = 0; %>
– <%! int a, b; double c: %>
– <%! Circle a = new Circle(2.0); %>
– You must declare a variable or method in a jsp page before
you use it
– The scope of a declaration is the jsp file, extending to all
includes
• <%= . . %> defines an expression and casts the result
as a string
20. Scripting II
• <%= . . %> can contain any language expression, but
without a semicolon, e.g.
• <%= Math.sqrt(2) %>
• <%= items[I] %>
• <%= a + b + c %>
• <%= new java.util.Date() %>
• <% . . %> can handle declarations (page scope),
expressions, or any other type of code fragment
• <% for(int I = 0; I < 10; I++) {
out.println(“<B> Hello World: “ + I); } %>
21. JSP and Scope
• Page - objects with page scope are accessible only within the
page where they are created
• Request - objects with request scope are accessible from
pages processing the same request where they were created
• Session - ojbects with session scope are accessible from pages
processing requests that are in the same session as the one in
which they were created
• Application - objects with application scope are accessible
from pages processing requests that are in the same
application as the one in which they were created
• All the different scopes behave as a single name space
22. Implicit Objects
• These objects do not need to be declared or instantiated by
the JSP author, but are provided by the container (jsp engine)
in the implementation class
• request Object (javax.servlet.ServletRequest)
• response Object (javax.servlet.ServletResponse)
• session Object (javax.servlet.http.HttpSession)
• application Object
• out Object
• config Object
• page Object
• pageContext Object (javax.servlet.jsp.PageContext)
• exception
25. Why Servlet/JSP?
What is an Enterprise Application?
• Reliable
• Scalable
• Maintainable
• Manageable
– If you are developing an Enterprise Application for
whose daily transactions are millions?
• Performance? Scalability? Reliability?
