can not schedule an exam

Question

Hello,
I can not schedule the exams i've created.
I've done everything. I've added questions, managed groups, created users and create question papers.
whenever I select schedule exam, (I fill every blanks it asks) it passes next page but never schedule exam.
Please help me to solve this problem.
p.s: I'm using Kaldin 2.1
        

Answer 1

Hi karoks,

It seems that you have to use latest MySQL connector in Kaldin.

• Download latest jar file from below link.

http://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.26.zip/from/http://cdn.mysql.com/

• Copy mysql-connector-java-x.x.x.jar from downloaded archive and paste into "lib" folder of kaldin installation directory, remove old version of jar file from "lib" folder.
• Open kaldin-installation-directory/webapps/kaldin/WEB-INF/lib/. Locate mysql-connector-java.x.x.x.jar and remove it.
• Restart Kaldin & Check again.
• If you still persist this issue. Please provide error log from catalina.out, you can find this file in "log" directory of kaldin installation folder.

Thanks
