Where do you have to place the MySQL Driver Jar to work?

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
