Re: AW: AW: [JBoss-user] JBoss3.2.1 violates fk constraints

Yes, exactly.

10.3.4.1 Remove methods
"When the remove method is invoked on an entity object, the container
must invoke the entity Bean Provider’s ejbRemove() method as described
in Section 10.5.3. After the bean provider’s ejbRemove() method
returns (and prior to returning to the client), the Container must
remove the entity object from all relationships in which it
participates, and then remove its persistent representation."

But Jboss just removes the link between the parent and the child by erasing
the attribute of the table (for example address_id) and then removes the parent
from the table. Is this the correct behavior ?

Hello Ingo,

yes, you have to check it yourself. If the schema you use has database
constraints, then the db won't let you remove the parent.
