if(rs.next())

{

out.print("<h4> Database Technology : " + rs.getString(2)+"</h4>");

out.print("<h4> Compiler Design : " + rs.getString(3)+"</h4>");

out.print("<h4> Object Oriented Analysis and Design ; " + rs.getString(4)+"</h4>");

out.print("<h4> Web Technology : " + rs.getString(5)+"</h4>");

out.print("<h4> Information Security : " + rs.getString(6)+"</h4>");

out.print("<h4> High Speed Networks : " + rs.getString(7)+"</h4>");

}

else

{

out.println("<h1>Invalid Register Number</h1>");

} }

catch(Exception e)

{

out.println("<h1>"+qr+"<br>"+e+"</h1>");

}

finally

{

out.println("</body>");

out.println("</html>");

out.close();

}

}

}

Output:

Client side Application

Servlet Output:

Result:

Thus a server side page to display results of a student using Servlet created successfully.
