HelloDemo.java
Java
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloDemo extends GenericServlet {
public void service(ServletRequest request, ServletResponse response)
throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Hello MSBTE example</title>");

out.println("<body>");
out.println("<h1>Hello MSBTE</h1>");
out.println("</body>");
out.println("</html>");
}
}

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ParameterDemo extends GenericServlet {
public void service(ServletRequest request, ServletResponse response)
throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String name = request.getParameter("sname");
String roll=request.getParameter("sroll");
out.println("<html>");
out.println("<head>");
out.println("<title>Parameter example</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Parameter Example</h1>");
out.println("<h2>Wlecome "+name+"</h2>");
out.println("<h2>Your roll number is :"+roll+"</h2>");
out.println("</body>");
out.println("</html>");
}
}
