Java – Persistence.xml not correctly configured

I'm not able to get this persistence file correct… I do not find any more information in the book that I use as a guide. I'm using a MySQL database.

<?xml version="1.0" encoding="UTF-8"?>
    <persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
      <persistence-unit name="a11_DA_g5_PU" transaction-type="JTA">
        <jta-data-source>a11_DA_g5</jta-data-source>
        <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
        <class>entities.Book</class>
        <class>entities.Author</class>
        <class>entities.Customer</class>
        <class>entities.Membership</class>
        <properties>
          <property name="eclipselink.target-database" value="DERBY"/>
          <property name="javax.persistence.jdbc.driver" value="org.apache.derby.jdbc.ClientDriver"/>
          <property name="javax.persistence.jdbc.url" value="jdbc:mysql://studev.groept.be:3306/a11_DA_g5"/>
          <property name="javax.persistence.jdbc.user" value="a11_DA_g5"/>
          <property name="javax.persistence.jdbc.password" value="passwordhere"/>
          <property name="eclipselink.ddl-generation" value="create-tables"/>
        </properties>
      </persistence-unit>
    </persistence>
