Hibernate save Oracle Number

I am having issues with Hibernate save. I wanted the newly created primary key so I had saved the object but it gives me a class cast exception. Persist works just fine.

Employee e = sessionFactory.getCurrentSession().save does not work
sessionFactory.getCurrentSession().persist works

java.lang.ClassCastException: java.lang.Long incompatible with com.test.Employee
java.math.BigDecimal incompatible with com.test.Employee -- If I change it to BigDecimal

Oracle column - "ID" NUMBER(36 , 0) NOT NULL

@Id
@GeneratedValue(generator = "testKey")
@SequenceGenerator(name = "testKey", sequenceName = "ID_SEQ")
@Column(name = "ID")
private Long id;

Should I be using something other than Long
 
It is sorta covered in the JavaRanch Style Guide.
