Iniciando no Hibernate

Pessoal, estou com problema ao rodar o código à seguir:

package hibernate;

import java.io.Serializable;

import javax.persistence.CascadeType;

import javax.persistence.Column;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import <a href="http://javax.persistence.Id">javax.persistence.Id</a>;

import javax.persistence.JoinColumn;

import javax.persistence.JoinTable;

import javax.persistence.OneToOne;

import javax.persistence.Table;

@Entity

@Table(name = “USER”)

public class User implements Serializable {

@Id

@GeneratedValue

@Column(name = “USER_ID”)

private Long id;

public Long getId() {

return id;

}

public void setId(Long id) {
	this.id = id;
} 

@OneToOne(optional=true, cascade = CascadeType.ALL)
@JoinTable(name="UserAddress", joinColumns={
		@JoinColumn(name="USER_ID", unique=true)
}, inverseJoinColumns = {
		@JoinColumn(name="addressId")
})
private Address shippingAddress;

public Address getShippingAddress() {
	return shippingAddress;
}

public void setShippingAddress(Address shippingAddress) {
	this.shippingAddress = shippingAddress;
}

}

package hibernate;

import java.io.Serializable;

import javax.persistence.Column;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import <a href="http://javax.persistence.Id">javax.persistence.Id</a>;

import javax.persistence.OneToOne;

import javax.persistence.Table;

@Entity
@Table(name = “ADDRESS”)

public class Address implements Serializable {

@Id

@GeneratedValue

@Column(name = “ADDRESS_ID”)

private Long id;

private String street;

private String city;

private String zipcode;

@OneToOne(optional=true, mappedBy=“shippingAddress”)

private User user;

public User getUser() {
	return user;
}

public void setUser(User user) {
	this.user = user;
}
 
public Long getId() {
	return id;
}

public void setId(Long id) {
	this.id = id;
}

public String getStreet() {
	return street;
}

public void setStreet(String street) {
	this.street = street;
}

public String getCity() {
	return city;
}

public void setCity(String city) {
	this.city = city;
}

public String getZipcode() {
	return zipcode;
}

public void setZipcode(String zipcode) {
	this.zipcode = zipcode;
}

}

package hibernate;

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.hibernate.Transaction;

public class Example1 {

public static void main(String[] args) throws Exception {

/** Getting the Session Factory and session <em>/

SessionFactory session = HibernateUtil.getSessionFactory();

Session sess = session.getCurrentSession();

/</em>* Starting the Transaction <em>/

Transaction tx = sess.beginTransaction();

/</em>* Creating Pojo <em>/

User newUser = new User();

<a href="//newUser.setId">//newUser.setId</a>(1L);

Address shippingAddress = new Address();

newUser.setShippingAddress(shippingAddress);

shippingAddress.setUser(newUser);

/</em>* Saving POJO <em>/

sess.saveOrUpdate(newUser);

/</em>* Commiting the changes */

tx.commit();
	System.out.println("Record Inserted");
	/** Closing Session */
	

	
	session.close();
}

}

O erro lançado é:

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.annotations.Version).

log4j:WARN Please initialize the log4j system properly.
