>                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-581
>             Project: Hibernate Tools
>          Issue Type: Bug
>          Components: reverse-engineer
>    Affects Versions: 3.1beta4
>            Reporter: Matt Read
>
> My hibernate.reveng.xml contains the following:
> 	<table catalog="Swan" schema="InsuranceLedger" name="jouJournal">
> 		<primary-key>
> 			<generator class="IDENTITY"></generator>
> 		</primary-key>
> 	</table>
> This results in the following annotations on my @Id field when generating annotated Java:
>     @GenericGenerator(name="generator", strategy="IDENTITY", parameters = { } )
> @Id @GeneratedValue(generator="generator")
>     @Column(name="jouSID", unique=true, nullable=false, insertable=true, updatable=true)
>     public Long getsID() {
>         return this.sID;
>     }
> Which results in the following error at runtime:
> org.hibernate.MappingException: could not instantiate id generator
> 	at org.hibernate.id.IdentifierGeneratorFactory.create(IdentifierGeneratorFactory.java:97)
> 	at org.hibernate.mapping.SimpleValue.createIdentifierGenerator(SimpleValue.java:152)

> Replacing the generated annotation with the following works fine:
>     @Id
>     @GeneratedValue(strategy=GenerationType.IDENTITY)
>     @Column(name="jouSID", unique=true, nullable=false, insertable=true, updatable=true)
>     public Long getsID() {
>         return this.sID;
>     }
