I Want to Map Class in Hibernate with Key to The table itself, by Hibernate not let it happen:

@Entity public class someclass {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
protected int id;
@ManyToOne
protected someclass parent;
private Double value;}

My xml file

<property
name="hibernate.hbm2ddl.auto">create</property>

And error:

Unable to execute command [alter table someclass drop
foreign key FKjyit8vtv8upkxd7wgt4wtoj0g] Caused by:
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table
'someclass.someclass' doesn't exist

How to Map it Correctly?
