Answer 1

Some of the latest Nolio versions doesn't support Mysql out of the box, and require some configuration for it. This is the Nolio knowledge base, on how to configure version 4.7 to work with Mysql - Nolio 4.7 - Custom Installation without Database Configuration This should solve your problem.

Answer 2

I had the same exception while trying to configure the PersistentManager with a JDBC Store using MySQL. I just had to copy the mysql-connector jar (for instance mysql-connector-java-5.1.34-bin.jar) to my tomcat library directory ([tomcatDir]/lib/.)

If the connection string is incorrect you get another error:

org.apache.catalina.session.JDBCStore getConnection
SEVERE: A SQL exception occurred com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown database 'invalidDB'
