ERROR: org.hibernate.util.JDBCExceptionReporter - Cannot load JDBC driver class 'com.mysql.jdbcDriver'
39,735
You've got the wrong driver name here:
jdbc.driverClassName=com.mysql.jdbcDriver
It should be:
jdbc.driverClassName=com.mysql.jdbc.Driver
Note the . between jdbc and Driver.
The way to diagnose similar things is to look at the class that it couldn't find:
Cannot load JDBC driver class 'com.mysql.jdbcDriver'
That already looks suspicious as the name jdbcDriver doesn't follow Java naming conventions. So at that point you then double-check what it should really be - e.g. by looking in the jar file - and fix the configuration.
As noted in comments, I don't think it's a good idea to have multiple versions of the same jar file on the classpath though - I can't see that ending well.

I'm trying to configurate a Java MVC webapp with Spring and Hibernate, and MySQL database, but when I run the server I have this error, and I don't know what's the problem.
