[Hibernate] JPA Question : Deletion w.r.t One-to-many relation

[The R. <the...@gm...>]

Hi,

Am a newbie to Java Persistence API. In our database, we have a one-to-many
relationship between 2 tables, say t1 & t2 i.e. one record of t1 can be
associated with multiple records in table t2. Is it possible to delete a row
in t2 without doing anything to the associated row in t1? Is this allowed in
JPA? I heard that an error saying "parent is null' is thrown in such a case?

Thanks.
