EX.NO: 8(b) PROGRAM USING SAX WITH XML
DATE:
AIM:
To write a program using SAX along with XML file.
ALGORITHM:
Step 1: Start the program
Step 2: Keep the xml and java file in the same folder.
Step 3: Import the required packages initially.
Step 4: Use Buffer Reader to read the contents from the command prompt.
Step 5: Get the name of the xml file from the user to execute.
Step 6: Using XML Reader Factory obtain the parser.
Step 7: If the document is correctly parsed then print document is well formed else print document is not well formed.
Step 8: Stop the program.
Coding:
import java.io.*;
import org.xml.sax.*;
import org.xml.sax.helpers.*;
public class Parsing_SAXDemo
{
public static void main(String[] args) throws IOException
{
try
{
System.out.print("Enter the name of XML document ");
BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
String file_name = input.readLine();
File fp = new File(file_name);
if (fp.exists())
{
try
{
XMLReader reader = XMLReaderFactory.createXMLReader();
reader.parse(file_name);
System.out.println(file_name + " is well-formed.");
}
catch (Exception e)
{
System.out.println(file_name + " is not well-formed.");
System.exit(1);
}
}
else
{
System.out.println("File is not present: " + file_name);
}
}
catch (IOException ex){ex.printStackTrace();}
}
}

OUTPUT:
XMLnot well formed program:
XML well formed program:

RESULT:
Thus the program for SAX is successfully executed and output is verified.
EX.NO: 9 PROGRAM USING AJAX
DATE:
Aim:
To write programs to search and display chemistry element’s definition detail using JSP.
Algorithm:
Step 1: Start the Program
Step 2: Enter the chemistry element in index.html
Step 3: Read the element data by request.getParameter() on chems.jsp.
Step 4: Check given element in element list.
Step 5: Display the definition of given element.

EX.NO: 10 web service-DATABASE CONNECTIVITY
DATE:
AIM:
To implement a program to run the web service.
ALGORITHM:
Step 1: Start the Program
Step 2: Create a new service web application as server in net beans
Step 3: In the server side web application, save the NewWebService program in java extension.
Step 4: In the web service side name the pack as pack1
Step 5: Clean and build the server side and then text the web service
Step 6: Create the client side as web application client and save the programs in jsp and html extension
Step 7: Clean and build the server side and then text the web service client
Step 8: Stop the Program
