You have to follow all that user1877955 said, and add this code, to avoid ClassCastException:

web.xml

    com.bla.Init

Init.java

package com.bla;

import javax.servlet.ServletContextEvent;

public class Initjavax.servlet.ServletContextListener {

    public void contextDestroyed(ServletContextEvent arg0) {

    }

    public void contextInitialized(ServletContextEvent arg0) {
        HibernatePersistenceProviderResolver.register();
    }
}

HibernatePersistenceProviderResolver.java

package com.bla;

import java.util.Collections;
import java.util.List;
import java.util.logging.Logger;

import javax.persistence.spi.PersistenceProvider;
import javax.persistence.spi.PersistenceProviderResolver;
import javax.persistence.spi.PersistenceProviderResolverHolder;

import org.hibernate.ejb.HibernatePersistence;

public class HibernatePersistenceProviderResolver implements PersistenceProviderResolver {
    private static final Logger LOGGER = Logger.getLogger(HibernatePersistenceProviderResolver.class.getName());

    private volatile PersistenceProvider persistenceProvider = new HibernatePersistence();

    public List getPersistenceProviders() {
        return Collections.singletonList(persistenceProvider);
    }

    public void clearCachedProviders() {
        persistenceProvider = new HibernatePersistence();
    }

    public static void register() {
        LOGGER.info("Registering HibernatePersistenceProviderResolver");
        PersistenceProviderResolverHolder.setPersistenceProviderResolver(new HibernatePersistenceProviderResolver());
    }
}
