STEP 2: Write a sample XML program.

STEP 3: Write a DOM Parser program using java by including the necessary

package.

STEP 4: Execute the java program by including the XML file as an argument.

STEP 5: Write a SAX Parser program using java by including the necessary

package.

STEP 6: Execute the java program by including the XML file as an argument.

STEP 7:Stop the program.

EX.NO:9 PROGRAM USING AJAX

AIM:

To Write a Programs using Asynchronous Java Script and XML.

ALGORITHM:


STEP 2: Write a program using html that includes the necessary tags and java

script function and object (XMLHttpRequest)

STEP 3: Update the web page using the content given in an input file.


CODING:

Ajax.html

//source file

<html>

<head>

<script type="text/javascript">

function loadXMLDoc()

{

if (window.XMLHttpRequest)

{// code for IE7+, Firefox, Chrome, Opera, Safari

xmlhttp=new XMLHttpRequest();

}

else

{// code for IE6, IE5

xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");

}

xmlhttp.onreadystatechange=function()

{

if (xmlhttp.readyState==4 && xmlhttp.status==200)

{

document.getElementById("myDiv").innerHTML=xmlhttp.responseText;

}

}

xmlhttp.open("GET","ajax_info.txt",true);

xmlhttp.send();

}

</script>

</head>

<body>

<div id="myDiv"><h2>Let AJAX change this text</h2></div>

<button type="button" onclick="loadXMLDoc()">Change Content</button>

</body>

</html>

//input file ajax_info.txt

AJAX is not a new programming language.

AJAX is a technique for creating fast and dynamic web pages.

OUTPUT:

RESULT:

Thus the program using Asynchronous Javascript and XML (AJAX) has been executed

successfully.

Ex.no:10. WEB SERVICE AND DATABASE

AIM:

To create an airline service and a travel agent and the travel agent is searching for an

airline using web services and database

ALOGRITHM:

Step 1: Create webpage in jsp with airline service information for travel agencies.

Step 2: Create database for airline in MSAcess.

Step 3: Connect the database with servlet.

Step 4: Open jsp file using any servlet and also open database file

Step 5: Enter the details and update it.

Step 6: Stop the program.
