How to connect with mysql

[tamakochang]

Now I'm getting stuck.  I cant connect to Activiti Explorer after I change db.properties to be

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/activitiDB?autoReconnect=true
jdbc.username=root
jdbc.password=ta_280332

Please tell me steps to connect Activiti using mysql.

P.S. I use Activiti-5.12 implementing with Apache-Tomcat7

Thank you for you help

What stacktrace do you see when you boot the Tomcat server?
