ONLINE EXAMINATION USING JSP

AIM:
      To create a three tier application for conducting online examination using JSP and database.

ALGORITHM:

1.       Design the HTML page (ExamClient.html) with the following
a)      Create a form to get the input from the user.
b)      Use radio buttons to make various options for the questions.
c)       Set the URL of the server (ExamServer.jsp) as the value of the action attribute.
d)       Use submit button to invoke the server and send the form data to the server.
2.       Create the JSP file with the following
a)       Read the input from the client.
b)       Retrieve the answers from the database.
c)       Match the answers from the user with the correct answers from the database table.
d)       For each correct answer increment the mark by 5.
e)       Server displays the mark and result to the client as a response.
