Great question. I'm trying to work through this now as I believe it is the root cause of a namespace error I'm having. If you are using Maven you will probably need to put it there; otherwise, in your classpath.

BTW... If you are using maven add this to your pom:

mysql mysql-connector-java 5.1.23

Can I change transaction type to JTA?

My web project is run on Glassfish server and using j2ee 7. But I couldn't connect to mySql server.

I config persistence.xml file like yours, it don't connect to mySql db but connect to derby

@khacsinhcs you're probably using Netbeans. That problem is common to netbeans.

mine is throwing an exception error like this "Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]"
what to do
i cannot able to connect to mysql database

IT AINT FUCKING WORKING CUNTS

very good. thanks

if im using mysql in xampp do i need to put org.hibernate.dialect.MySQL5Dialec in the application properties of spring boot prj ?

org.hibernate.ejb.HibernatePersistence

change the above line to

org.hibernate.jpa.HibernatePersistenceProvider

I executed that persistence.xml and then the Hibernate show me this message

23:50:44.846 [main] WARN org.hibernate.orm.connections.pooling - HHH10001002: Using Hibernate built-in connection pool (not for production use!)
Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

Therefore, I recommend to change this to the under line

<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />

->

<property name="javax.persistence.jdbc.driver" value="com.mysql.cj.jdbc.Driver"/>
