Java Online Exam System

I have posted a new open source project on sourceforge.net

Overview:
Online examination system using JEE where system can be customized to work in universities , schools and companies (interview tool).

URL:
http://sourceforge.net/projects/online-exam4j/

Features:
- Online Customizable Examination System.
- Auto-submit when time ends up.
- Support single selection and multiple selection.
- Easy navigation.
- Support text and Image-based questions.
- Configurable (even question per page, email sending, ...)
- Send emails to examine and examiner according to configurations.
- Auto-submit when time ends up.
- Work well with IE and FF and other browsers.
- Work well with page reload/refresh (no answers/timer lost)
- Used Ajax for better efficiency.
- Voucher based system (can be renewed after expired)
- Audit user actions.
- No admin interface currently and uses Query Browser of MySQL instead.
- Support pauses for 5 min.
- Support UTF8 for all languages.

How To Run:
1-Import DB schema into MySQL DB.
2-Open the DB "Exam" schema, do few changes in Config table per your custom data.
3-Deploy the WAR file into Glassfish V3 server (you may need to create the DataSource but mostly you won't need this step).
4.Test the application using : valid vouchers: 123456 or 123455
Application URL would looks like:

http://localhost:8080/ExamSystem/

-localhost and port could differ according to your server IP and port.


Future Work:
-Add admin interface.
-Support Voucher Types (each voucher for a dedicated exam).
-Support report and print certificate/report/exam.
-Statistical analysis of the exam data.

  4. The project works fine on the glassfish3 server. You need to appropriately adjust the settings for the application to work. The .war file does not work in Tomcat.

    1. You can do the following in sequence:
      1. Check server log for any exception?
      2. Check DB port ?
      3. Check server port in the requested URL
      4. Check the server admin console

  18. Sir, I get this message all the time : HTTP 404 not found.
    1. What should I do?
    2. And where to configure the db, in mysql or in netbeans?

    ReplyDelete
    Replies
    1. This means the application is not configured properly.
      DB need to be imported inside my SQL and define the datasource in NetBeans in web.xml.

      Delete
    2. Thanks for the help Sir, but still after configuring the datasource and all, I am having the same problem (after entering voucher number). Please refer the link below, I have attached some screenshots :

      https://www.dropbox.com/sh/wwlr6mbfdjwfx38/AACCchF8cxDPyf7zrshqrnlTa?dl=0

      I think the problem is with that nullpointerexception in the glass fish logs.
      also, browser log says "failed to load resource".
      Thanks

      Delete
    3. The issue here is the data source configurations is still not working, you can create the datasource in Glassfish admin console directly and you only need to use JNDI name: "jdbc/ExamSys".
      You can also add username and password to the configurations.
