Hi.
I've used the sequence of Oralce 9i.
So I changed the @ID Annotation in the ManyToMany and OneToOne Relationship Tutorial as below.

@Id(generate = GeneratorType.IDENTITY) => @Id(generate = GeneratorType.SEQUENCE, generator="EJB3_SEQ")

and I've created the sequence as "EJB3_SEQ" to the Oracle 9i

There is an error message after deploy it as below.

09:31:53,075 ERROR [Ejb3Module] Starting failed jboss.j2ee:service=EJB3,module=Relationship.ejb3
org.hibernate.MappingException: org.dom4j.DocumentException: Error on line 13 of document : The element type "generator" must be terminated by the matching end

Please let me know how to use the sequence ?
