Problemas com conexão mysql

Estou iniciando com hibernate + jsf + ajax estou fazendo exemplo do blog Java Anywhere do eduardo bregaida so que quando eu vou executar a classe geraBanco ele da seguinte erro :

import org.hibernate.cfg.AnnotationConfiguration;

import org.hibernate.cfg.Configuration;

import org.hibernate.tool.hbm2ddl.SchemaExport;

public class GeraBanco {

public static void main(String[] args) {

Configuration configuration = new AnnotationConfiguration();

configuration.configure();

SchemaExport schemaExport = new SchemaExport(configuration);

schemaExport.create(true, true);

}

}

e as exceções foram as seguintes:
