What is the DOM?
The DOM is a W3C (World Wide Web Consortium) standard.
The DOM defines a standard for accessing documents:
"The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document."
The W3C DOM standard is separated into 3 different parts:
Core DOM - standard model for all document types
XML DOM - standard model for XML documents
HTML DOM - standard model for HTML documents
The HTML DOM (Document Object Model)
When a web page is loaded, the browser creates a Document Object Model of the page.
The HTML DOM model is constructed as a tree of Objects.
With the HTML DOM, JavaScript can access and change all the elements of an HTML document.
The Browser Object Model (BOM) in JavaScript includes the properties and methods for JavaScript to interact with the web browser.
BOM provides you with window object, for example, to show the width and height of the window. It also includes the window.screen object to show the width and height of the screen.
The document describes a Java program to create a color palette applet with the following features:
1. Create a matrix of buttons to display a color palette.
2. Allow the user to select a color from the palette to set the background or foreground of a text area control.
3. Use a checkbox control as radio buttons to select whether the selected color sets the background or foreground.
The algorithm defines the necessary classes and objects, adds the controls to the applet using init(), arranges the controls with setBounds(), sets button backgrounds with setBackground(), adds listeners, and conditionally sets the text area background or foreground based on the checkbox selection.
This document discusses JavaScript events and event listeners. It begins with an introduction that defines events as notifications that specific actions occurred, like user or browser actions. Event handlers are scripts that are executed in response to events. Events can be used to trigger JavaScript code that responds to user interactions. The document then provides examples of common event types like onclick, onsubmit, onmouseover, onmouseout, focus, and blur. It also discusses how to add and remove event listeners using addEventListener() and removeEventListener() methods. The document concludes with an example demonstrating how events can be used to change an HTML element in response to user clicks.

A.I. refers to the capability of machines to imitate intelligent human behavior. The history of A.I. began in the 1950s but has improved greatly in recent decades with advances like Sophia robot. A.I. is needed because humans have physical limitations, while robots can perform dangerous jobs. A.I. is created through a combination of programming, hardware, and sensors. It has many applications like healthcare, education, industry, finance, and customer support. While A.I. provides benefits like low error rates and replacing humans in dangerous jobs, there are also disadvantages such as high costs, lack of creativity, and potential unemployment. The future of A.I. could include automated transportation, cyborg technology

22. Experiment: -7
Objective: -Install TOMCAT web server and APACHE. Access the above developed
static web pages for books web site, using these servers by putting the web pages
developed.
Program:- install TOMCATE web server and APACHE and Access them
Downloading the Tomcat Installer
1. Access the Tomcat Download page. Open a new browser tab or window and enter “Apache Tomcat 7
download” in the address bar. Hit the Enter key to view the search results. Select the first link in the results
from the official Apache Tomcat page.
Tomcat 7 is the latest version, though you can select earlier versions from the left menu
panel on the download page.
2. Download the installer zip file. Go down the page to find the “Binary distribution” folder
under the “7.0.62” heading. In the folder, locate “Binary Distribution/Core” heading and
click the “Zip” link to download the installer. #* The unitary file size of the zip package is
around 8MB.
3. Unzip the installer. Go to the “Download” folder of your computer and unzip the file with
WinZip or WinRAR, or whatever unzipping program you have. Avoid unzipping the folder
to the desktop, as you will find the path of the software files hard to locate later. The best
option will be to unzip to “E:myserver.” The unzipped directory will be
“E:myservertomcat-.0.62.”
Part2
Installing Tomcat
1. Check the installation directory. Check the installed directory to ensure it contains all the
sub folders (bin, logs, webapps, work, temp, conf, and lib). These are the required
subfolders for installing the server. If any of the folder is missing, download the zip file
again.
2. Create JAVA_HOME. After checking the directory, you should create an environment
variable called “JAVA_HOME.” To do this, go to Start >> Control Panel >> System >>
Advanced System Settings. After reaching it, click the “Advanced” tab, then click
Environment Variables >> System Variables.
Select the “New” button in the System Variables menu. In the “Variable name” field, enter
“JAVA_HOME.” Enter “c:Program FilesJavajdk1.7.0_{xx}” in the “Variable value” field.
(Variable value is nothing but the JDK directory, you can always find this in program files.)
3. Ensure its workability. To make sure that it’s working correctly, start a command shell
and issue: set JAVA_HOME. To open the command shell, click the “Start” button and then
“All Programs”. Type the following in the command prompt, “set JAVA_HOME =
23. C:Program FilesJavajdk1.6.0_06” and press enter. The JAVA_HOME is set. Type the
following in the command prompt, “set JAVA_HOME = C:Program FilesJavajdk1.6.0_06”
and press enter. The JAVA_HOME is set.
4. Create JRE_HOME. At times, you may need to set JRE_HOME instead of JAVA_HOME,
like errors when using Java. If this is the case, JRE should be used. Create JRE_HOME
the same way you created Java, but remember that the JRE installed directory will be
different (C:Program FilesJavajre7).
Part3
Configuring Tomcat
1. Locate the configuration files. Locate the four configuration XML files of Tomcat in the
“conf” sub-directory of the Tomcat directory (E:myservertomcat7.0.40conf). The four files
should be context.xml, tomcat-users.xml, server.xml, and web.xml file.
2. Create a backup. Before proceeding, make a backup of the configuration files. Because of
file permissions with your backup/restore, you don’t want to restore the server with
different file permissions than what was there originally.
To do this, go to Internet router >> Prompt, issue the Enable command by entering
“Enable,” and provide the required password when prompted. A page will be displayed
with your router settings. Entering “Enable” will change the prompt to Router#, which
indicates that the router is now in privileged mode. Copy the running configuration file to
the TFTP server.
Afterwards, open the configuration file with a text editor, like Textpad or Notepad. Search
for and remove any line that starts with “AAA.” Copy the configuration file from the TFTP
server to a new router in privileged (enable) mode, which has a basic configuration.
3. Enable directory listing. Open the configuration file “web.xml” in a text editor, and change
the directory listing by changing “listings” from “false” to “true” for the “default” servlet.
4. Set the TCP Port Number. Open the configuration file “server.xml” in a text editor. The
default port number of Tomcat is 8080. Now you need to change this, since the same port
number can be used by other servers like SQL Server. You may choose any number
between 1024 and 65535.
5. Enable automatic reload. Open the configuration file “context.xml” in a text editor. Here,
set reloadable=“true” to the <Context> element to enable automatic reload after the code
changes.
Part4
Starting Tomcat
1. Run the startup. Launch the command prompt in Windows 7. Once launched, set the
current directory to “<TOMCAT_HOME>bin”. For example, E:myservertomcat7.0.40bin,
and run “startup.bat”.
24. When you first start the command prompt, you will be located in your personal directory.
This is typically C:Usersusername. With the basic navigation commands, you can set the
directory as specified in the above step.
2. Start the server. This will direct you to a new console window of the server. Read the
messages that appear on the console. Look out for the Tomcat’s port number and double-
check.
3. Access Tomcat. Open any web browser on your Windows and then enter the URL
“http://localhost:9999”. This will direct you to the Tomcat server’s welcome page. Once you
are directed to the server page, you are almost done. Now try the URL
“http://localhost:9999/examples” to view JSP and servlet examples.
4. Tomcat when you’re done. To do this, press Ctrl + C in the Tomcat console.
25. Experiment: -8
Objective:- Assume four users user1, user2, user3 and user4 having the passwords
pwd1, pwd2, pwd3 and pwd4 respectively. Write a servlet for doing the following.

27. Experiment: -9
Objective: -Install a database (Mysql or Oracle). Create a table which should contain at
least the following fields: name, password, email-id, phone number Write a java
program/servlet/JSP to connect to that database and extract data from the tables and
display them. Insert the details of the users who register with the web site, whenever
a new user clicks the submit button in the registration page.
Install a Database (Mysql or Oracle):-
Step 1: download MySQL
Download MySQL from dev.mysql.com/downloads/. Follow MySQL Community
Server, Windows and download the “Without installer” version.
As always, virus scan the file and check the its MD5 checksum using a tool such as fsum.
Step 2: extract the files
We will install MySQL to C:mysql, so extract the ZIP to your C: drive and rename the
folder from “mysql-x.x.xx-win32” to “mysql”.
MySQL can be installed anywhere on your system. If you want a lightweight installation, you
can remove every sub-folder except for bin, data, scripts and share.
Step 3: move the data folder (optional)
I recommend placing the data folder on another drive or partition to make backups
and re-installation easier. For the purposes of this example, we will create a folder
called D:MySQLdata and move the contents of C:mysqldata into it.
You should now have two folders, D:MySQLdatamysql and D:MySQLdatatest. The original
C:mysqldata folder can be removed.
Step 4: create a configuration file
MySQL provides several configuration methods but, in general, it is easiest to to
create a my.ini file in the mysql folder. There are hundreds of options to tweak MySQL
to your exact requirements, but the simplest my.ini file is:
[mysqld]
# installation directory
basedir="C:/mysql/"
# data directory
datadir="D:/MySQLdata/"
(Remember to change these folder locations if you have installed MySQL or the data folder
elsewhere.)
Step 5: test your installation
The MySQL server is started by running C:mysqlbinmysqld.exe. Open a command box
(Start > Run > cmd) and enter the following commands:
28. cd mysqlbin
mysqld
This will start the MySQL server which listens for requests on localhost port 3306. You can
now start the MySQL command line tool and connect to the database. Open another
command box and enter:
cd mysqlbin
mysql -u root
This will show a welcome message and the mysql> prompt. Enter “show databases;” to view
a list of the pre-defined databases.
Step 6: change the root password
The MySQL root user is an all-powerful account that can create and destroy
databases. If you are on a shared network, it is advisable to change the default
(blank) password. From the mysql> prompt, enter:
UPDATE mysql.user SET password=PASSWORD("my-new-password") WHERE User='root';
FLUSH PRIVILEGES;
You will be prompted for the password the next time you start the MySQL command line.
Enter “exit” at the mysql> prompt to stop the command line client. You should now shut
down MySQL with the following command:
mysqladmin.exe -u root shutdown
Step 7: Install MySQL as a Windows service
The easiest way to start MySQL is to add it as a Windows service. From a command
prompt, enter:
cd mysqlbin
mysqld --install
Open the Control Panel, Administrative Tools, then Services and double-click MySQL. Set the
Startup type to “Automatic” to ensure MySQL starts every time you boot your PC.
Alternatively, set the Startup type to “Manual” and launch MySQL whenever you choose using
the command “net start mysql”.
29. Note that the Windows service can be removed using:
cd mysqlbin
mysqld –remove
