id without property

Hi,

in
http://www.hibernate.org/hib_docs/v3/re ... aration-id
I read that most classes will also have a JavaBeans-style property holding the unique identifier of an instance.

As described it is perfectly fine to ommit the name attribute in the <id> tag.

What is the equivalent of that in the annotations world?
How do I annotate classes that don't carry a property holding the unique identifier?

Read the EJB spec draft, entity beans need an identifier property.

maybe I don't understand the scope of Hibernate Annotations, but wouldn't that be a reson for something like:

Code:

package org.hibernate.annotations;
[...]
@Target(TYPE) @Retention(RUNTIME)
public @interface Id {
   String column();
   GeneratorType generate() default NONE;
   String generator() default "";
   [...]
}

The thing is that your request is quite uncommon and has some important drawbacks (unability to play with detached objects etc etc).
