Hi Sergio,

If you are the one from TDC, you will remember me :)

It seems like your issue here is the mysql driver that is in the lib folder. You need to update/replace your mysql driver located at [JIRA Installation Directory]\lib.

Here is the list of drivers:

https://confluence.atlassian.com/display/DOC/Database+JDBC+Drivers

1. Stop Tomcat (JIRA)

2. Stop MySQL

3. Replace/Update Driver

4. Start MySQL

5. Start Tomcat

I would delete the logs and check again.

Good luck and nice to hear from you if you are the Sergio that I know.

Mehmet
