[JBoss Eclipse IDE (users)] - Re: Cache-related error creating SessionFactory in Hibernate

I restarted Eclipse, and it worked the first time I tried to open the SessionFactory. Then, I ran a HQL query, and it threw an error, complaining that the table didn't exist.
So I edited the hibernate.cfg.xml file, correcting the database URL, and next time I tried to open the SessionFactory, I got:

[JBoss Seam] - Entity Scope question
by sjmenden
The seam docs are not completely clear on where an Entity lives when it exists in several scopes.
The following example:
| @Entity
| @Name("dog")
| @Scope(EVENT)
| @Role(name="currentDog", scope=SESSION)
| @Table(name="dogs")
| public class Dog implements Serializable {
| ....
|
So now, when exactly does my dog live in the EVENT scope and when does he live in the SESSION scope with the name currentDog.
Based on what I have observed so far, I would guess that the currentDog object gets put in the SESSION scope the first time I outject it, is that correct?
Also, if I outject the dog object
| @Out Dog dog.
|
Does this mean that the Dog object gets outjected to both EVENT(dog) and SESSION(currentDog)?
