JSP is a technology based on Java that produces dynamic web pages. JSP files contain HTML tags as well as special JSP tags where Java code is embedded. There are three main types of JSP elements - directives, scripting elements, and action elements. Directives provide information to the JSP engine, scripting elements contain Java code, and action elements perform tasks like accessing Java beans. Common implicit objects in JSP include application, page, session, and request objects. Java beans can be used with JSP through action tags like useBean, setProperty, and getProperty.
This slide is about basics of java servlet and java server page.
A basic example of JSP using multiple directives.
Further information of setting up and using of Apache Tomcat server.
JSP technology has facilitated the segregation of the work of a Web designer and a Web developer.
A Web designer can design and formulate the layout for the Web page by using HTML.
On the other hand, a Web developer working independently can use java code and other JSP specific tags to code the business logic.
The simultaneous construction of the static and dynamic content facilitates development of quality applications with increased productivity.

If you want to earn much in web development business, you also need to learn Java web technologies.
Java has de facto standart frameworks such as EJB 3.0, Spring and others that can be bound to them.
But at heart, they all use the similar JSP/Servlet technology and add some layers above them to speed up the development.
You will use them in your daily business but before using them, you must learn the basics and what is going on while using them. Otherwise, you will not be able to find a proper solution to common problems.
This course will make you understand the basics of JSP / servlet technlogies, designing a relational database, DB operations, design patterns, working with other developers,
and let you know the must-do operations in professional projects such as performance increasing, logging errors.
If you want to develop a web-site in a couple of hours without understanding what you are doing, you may go ahead and find other resources. But if you really want to understand what you are doing and learn the theory at the same time, this course will be a great oppurtunity for you. You will develop a real working project. Yow will first write quick and dirty code then you will apply professional patterns one by one while investigating the problems.
You will walk through a real development flow:
1- Write a quick and dirty code for doing the job.
2- You will design database tables and high performance queries
3 - You will apply design patterns to make the code reusable and high performance.

Creating JavaServer Pages (JSP) files
Most types of JSP files can be created using the New JSP File wizard. To create a basic JSP file using the wizard, complete the following steps:
Create a dynamic Web project if you have not already done so.
In the Project Explorer, expand your project and right click on your WebContent folder or on a subfolder under WebContent. Note that if you choose any other folder in which to create the JSP, then it will not be included in the WAR file that is deployed to the server. In addition, link validation will not encompass files that are not under the WebContent folder.
From the context menu, select New > JSP. The New Java Server Page window appears with your folder selected
Type a file name into the File name field, making sure you include the jsp extension (jsp, jsv, jtpl, or jspx) in the file name.
You have several options for proceeding:
To accept the defaults associated with a new JSP file, select Finish.
To link to a file in the file system and specify path variables, select Advanced and then make your selections using the Browse and Variables buttons.
To use a template file for the initial content of your JSP page, select Next. The Select JSP Template window appears. Select the Use JSP Template check box, and then select one of the sample templates. You can also select the JSP Templates link to add or remove JSP templates to your list of templates.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

JSP comments
JSP elements; Directives, Scripting, Actions
JSP implicit objects
Example of writing JSP
Java Bean
3. INTRODUCTION
JSP is a technology based in java which produces dynamic web
pages.
JSP is a server side scripting language technology created by
sun micro systems.
JSP files are html files which contains special tags where java
code is embedded into it.
JSP have .jsp extension.
4. JSP VS. ASP
JSP is technology introduced by Sun micro systems where as
ASP is a technology introduced y Microsoft.
JSP is abbreviation of JAVA SERVER PAGES and ASP is
abbreviation of ACTIVE SERVER PAGES
ASP pages can connect to my sql & ms Access databases and
also can connect to other database with the help of ADO
whereas JSP can connect to any database loading the
appropriate driver when needed.
5. JSP VS. ASP
ASP runs on Microsoft IIS server which run on Microsoft
operating system where as JSP can run on any Linux based
server, IBM JBOSS as well as in Microsoft platform.
ASP is an interpreted language, JSP can interpreted as well as
compiled.
JSP is free of cost including JSP server where as ASP is free
but running ASP on Microsoft IIS server cost money.
6. JSP LIFE CYCLES
JSP are deployed in the web server as servlet.
The JSP page is compiled to servlet by JSP engine, eliminating
the html tags and putting them inside out.println() statements
and removing the jsp tags.
Once it is translated into servlet then the servlet, then it
follows the servlet lifecycles.
8. JSP ERRORS
Three types of error can be evolved in JSP:-
Jsp error; which occurs when jsp is translated to servlet.
Java code error; occurs when the servlet is complied to java class.
HTML error; occurs during the presentation of html pages in the
browser.
9. JSP ERRORS
The first two errors (jsp error and java code error) is detected
by the application server.
The HTML error is detected by the web browser.
10. JSP COMMENTS
Comments can be include in the jsp page, follows:-
<%-- --%>
</* */>
<!-- --!>
11. JSP ELEMENTS
The elements in jsp contains the tags, each having special
meanings, containing java codes which tells the jsp engine
what/how dynamic output has to processed.
There are three types of elements:-
Directives
Scripting
Action
12. DIRECTIVES
Directives:- This tag is used to convey special information
about the page to the jsp engine.
Syntax:-
<%@ %>
Three kinds of Directives are available:-
page
include
tag library
13. DIRECTIVES
page directive ; this directive informs the jsp engine about the
headers and facilities that the page should get from the
environment.
There can be any number of page directives in a jsp page.
Declared usually at the top.
Syntax:-
<%@page attribute= %>
Attributes can be; include, import, session, etc.
Example; <%@page import=“package_name”%>
14. DIRECTIVES
Include directive ; this is used to statically include one or
more resources to the jsp page.
This allows the jsp developer to reuse the code.
Syntax:-
<%@include page=“”%>
There is only on attribute named „page‟ in include directive.
15. SCRIPTING ELEMENTS
Scripting Elements; contains embedded java code.
There are three types:-
Declarations
Expression
Scriplets
16. SCRIPTING ELEMENTS
Declarations; this tag allows the developer to declare one or
multiple variable and methods.
They do not produce any output.
Syntax:-
<%! %>
Example:- <%! public String name;
public int age;
public void setDetail(name,age); %>
17. SCRIPTING ELEMENTS
Expression; this tag allows the developer to embed single java
expression which is not terminated by a semi colon.
Syntax:-
<%= %>
Example:- <%= new java.util.Date() %>
18. SCRIPTING ELEMENTS
Scriplets; this tag allows the developer to embedded java code
inside it that can use the variable declared earlier.
Syntax:-
<% %>
Example:- <% int sum=a+b;
system.out.println(sum);
%>
19. ACTION ELEMENT
Functions provided like:-
Use of java bean technology in jsp page.
Browser independent support for applet.
Transfers control among pages.
Syntax:-
<jsp: />
20. ACTION ELEMENT
Standard action tag are:-
useBean
setProperty
getProperty
param
include
forward
plugin
21. JSP IMPLICIT OBJECTS
There are certain objects in jsp that can be used in jsp page without being
declared these are Implicit objects. There are nine implicit object in JSP:-
application
page
pageContext
config
session
exception
request
response
out
22. EXAMPLE OF JSP
A simple jsp program to show date using scriplets;” teddyTest.jsp”
<html>
<head>
</head>
<body>
<h1>JSP Page to show today Date </h1>
<% out.println(new java.util.Date()); %>
</body>
</html>
23. EXAMPLE OF JSP
Now we will use the implicit object to get values from a html page.
This is a html page to take user inputs “Impli.html”
<html>
<body>
<form ACTION=“ImpliShow.jsp”>
Name=<input type=“text” name=“nm”>
<input type=“submit”>
</form>
</body>
</html>
24. EXAMPLE OF JSP
ImpliShow.jsp
<html>
<body>
<%
String nm=request.getParameter("usr");
String ag=request.getParameter("age");
out.println (“name:”+nm+””+age:”+ag);
%>
</body>
</html>
25. JAVA BEAN
Java bean is a self contained class file in java which typically
contains;
No argument constructor.
Is seriliziable.
Have getter and setter methods to get and set values of the
properties.
According to java white papers java beans are reusable
component in java, and they combine various objects into a
single one which can be accessed by multiple user.
26. JAVA BEAN
Jsp use three action tag for use of java bean technology:-
useBean=used to locate or instantiate a bean class.
setProperty=set the property value or values of a bean class.
getProperty=get the property values of a bean class, first the
property values are converted into string and then added to the
request stream.
28. JAVA BEAN
Example of useBean action tag in jsp:-
Class student{
private String name;
Private int age;
public void setName(string n){
name=n;}
publci void setAge(int a){
age=n;}
}
29. JAVA BEAN
A html page named bean.html
<html>
<body>
<form ACTION=“teddyBean.jsp”>
Name=<input type=“text” name=“nm”>
<input type=“submit”>
</form>
</body>
</html>
32. JAVA BEAN
<jsp:setProperty name=“obj" property="name" value="*" />
To set all the values of the property.
<jsp:setProperty name=“obj” property=“_property”
value=“_value” />
To set a particular property with a value.
33. JAVA BEAN
Example of setProperty and getProperty action tag:-
Package teddyPack
public class jB {
private String name;
private int age;
public void setAge(int age){this.age=age;}
public void setName(String name){this.name=name;}
public String getName(){return name;}
public int getAge(){ return age;}
}
34. JAVA BEAN
A html page named “setGET.html”
<html>
<body>
<form ACTION=“setGet.jsp”>
Name:<input type=“text” name=“name”>
Age:<input type=“text” name=“age”>
<input type=“submit”>
</form>
</body></html>
