Problems with creating MySQL table with hibernate

At first I try to create table with names USERS or USER, but google said me that it is a reserved words in MySQL and I try with QWERTY, the table is not created anyway.

Entity Class

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="QWERTY")
public abstract class User {
    @Id
    @GeneratedValue
    protected Long id;
    protected String username;
    protected String firstname;
    protected String secondname;
    protected String middlename;
    protected String password;

    @Type(type = "org.hibernate.type.NumericBooleanType")
    protected Boolean accountIsNotLocked;

    public User(){  
    }   

    // getters and setters...
}

Creating table

import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.tool.hbm2ddl.SchemaExport;

import by.grsu.epam.domain.User;

public class TestUser {

    public static void main(String[] args) {
        AnnotationConfiguration config = new AnnotationConfiguration();
        config.addAnnotatedClass(User.class);
        config.configure();

        new SchemaExport(config).create(true, true);
    }

}

The logging shows that you are not setting the correct dialect (Using dialect: org.hibernate.dialect.HSQLDialect). So, you have to set the correct dialect: org.hibernate.dialect.MySqlDialect. Then Hibernate will generate the correct statements for MySQL.
