RE: [Andromda-user] 3.0m2 hibernate cartridge fails if <<entity>> does not declare a <<primary key>>

[Wouter Z. <wz...@br...>]

Hi Greg,

This will be handled more correctly in the next milestone release when
the validation has been put in place (currently still under
construction). The cartridge will then give you a more expressive
message instead of an exception.

Anyway, in Hibernate the id (or composite-id) element is mandatory so
one way or the other you will always need to specify what primary key to
use

Here a fragment from the hibernate mapping dtd:
(http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd)


<!ELEMENT class ( 
  meta*,
  (cache|jcs-cache)?,
  (id|composite-id),
  discriminator?,
  (version|timestamp)?,
 
(property|many-to-one|one-to-one|component|dynamic-component|any|map|set
|list|bag|idbag|array|primitive-array)*, 
  ((subclass*)|(joined-subclass*))
)>
