Hello Quadi BEL,

what is the version of your MySQL database and the driver? Because as I can see in the log, you use org.hibernate.dialect.MySQLDialect in your persistence.xml. Latest MySQL is of version 5 and it requires org.hibernate.dialectMySQL5Dialect (it's possible to try also MySQL5InnoDBDialect for InnoDB storage engine).
