I am new to Hibernate . I am getting the below exception while executing. Can anyone please help to resolve the problem

Here is the hbm file:

package org.java.dto;
import javax.persistence.Embedded;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.AttributeOverrides;
import javax.persistence.AttributeOverride;
import javax.persistence.Column;

@Entity
@Table(name="USER_DETAILS")
public class UserDetails {
@Id @GeneratedValue(strategy=GenerationType.AUTO)
private int userId;
private String userName;


@Embedded
@AttributeOverrides({
@AttributeOverride (name="street",column=@Column(name="HOME_STREET_NAME")),
@AttributeOverride (name="city",column=@Column(name="HOME_NAME_CITY")),
@AttributeOverride (name="state",column=@Column(name="HOME_STATE_NAME")),
@AttributeOverride (name="pincode",column=@Column(name="HOME_PIN_CODE"))

})

public Address getHomeAddress() {
return homeAddress;
}
public void setHomeAddress(Address homeAddress) {
this.homeAddress = homeAddress;
}
public Address getOfficeAddress() {
return officeAddress;
}
public void setOfficeAddress(Address officeAddress) {
this.officeAddress = officeAddress;
}
private Address homeAddress;
@Embedded
private Address officeAddress;


public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}

public String getUserName() {
return userName ;
}
public void setUserName(String userName) {
this.userName = userName;
}


}
