EMBEDDING AN IMAGE MAP IN AN HTML PAGE
Aim:
To create an html page with an embedded image and to fix the hotspots for linking.
Algorithm:
Step 1: Start the program.
Step 2: Create an html page and embed an image in it.
Step 3: Using the X-Y co-ordinates, fix the various hotspots used to link other pages.
Step 4: Create 4 different pages separately.
Step 5: Using link tag, connect each hotspot with its respective link page.
Step 6: Load the main html program, and check the links.
Step 7: Stop the program.

APPLYING STYLE TO AN HTML PAGE USING CSS
Aim:
To create an html page, and to apply style formatting using external Cascading Style Sheet.
Algorithm:
Step 1: Start the program.
Step 2: Create an html page.
Step 3: Create an external CSS (Cascading Style Sheet).
Step 4: Link the external style sheet page with the main html page.
Step 5: Load the main page.
Step 6: The style formatting will be applied to the main html page.

CREATION OF 3-TIER APPLICATION USING JSP AND DATABASE
Aim:
To develop a 3-tier application for displaying student’s mark list using java server pages and
MS-Access database.
Algorithm:
Step 1: Start the program.
Step 2: Create a MS-Access database table named student for storing student’s marks.
Step 3: Create an html form for entering the register number of the student.
Step 4: Open control panel and make the database connectivity settings.
Step 5: Create a JSP coding for processing the student’s marks from the database.
Step 6: Deploy the JSP and the html page in the Netbeans 6.8 IDE to create the application
package.
Step 7: Run the application in the IDE.
Step 8: The student’s mark list for the corresponding register number will be displayed.
Step 9: Stop the program.

PARSING XML DOCUMENT USING DOM API
Aim:
To write a java code using DOM API for parsing an XML document and check whether it is well
formatted or not.
Algorithm:
Step 1: Start the program.
Step 2: Create an XML document containing student’s information.
Step 3: Write a java code that import the various DOM related classes to parse the XML
document.
Step 4: Compile and run the java file which parses the document and displays whether the
created XML document is correctly formatted.
Step 5: Stop the program.
