Galera, depois de insistir muito com a conexão do eclipse com SQLServer, acabei sedendo para o MySQL, então fiz o download do SqlWorkbench e conectei, até ai tudo bem, mas quando coloquei meu codigo para funfar oia o que deu.

package Eventos.Ultil;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

import Eventos.classes.Usuarios;

public class Jdbc2 {
	public static void main(String args[]) {

		EntityManagerFactory factory = Persistence
				.createEntityManagerFactory("eventos");
		EntityManager em = factory.createEntityManager();

		Usuarios usu = new Usuarios();
		usu.setEmail("[email removido]");
		usu.setFone("2222-1111");
		usu.setNome("cassio");
		em.getTransaction();
		em.persist(usu);
		em.getTransaction().commit();

	}

}

Galera eu coloquei a pasta META-INF no classpath mas ai ele gerou o seguinte

Primeiro, você não possui um arquivo persistence,xml
Segundo, como este aquivo não existe, você não tem um EntityManager chamado eventos…

Eu te tenho o hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>

<hibernate-configuration>

	<session-factory>

		<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
		<property name="connection.url">jdbc:mysql://127.0.0.1:3306/mysql</property>
		<property name="connection.username">root</property>
		<property name="connection.password"></property>

		<property name="c3p0.min_size">5</property>
		<property name="c3p0.max_size">20</property>

hibernate.cfg.xml != persistence.xml

Você está misturando as coisas, tentando criar uma aplicação utilizando JPA e EntityManager, mas baseando-se em uma estrutura do hibernate.

Você deve definir se vai utilizar EntityManager, então, crie o persistence.xml
Senão, troque o EntityManager por Session e boa.

Sugestão, jogue fora o tutorial que está seguindo, procure pela documentação oficial ou mesmo, por exemplos na net.
