Relation load problem

[s0d0]

I'm having problem with entity beans.
When I use findByPrimaryKey to fetch one entity on "parent" table,
all child objects is fetched immediately. I have millions of records in child table so it kills performance. Is this normal behaviour?

I'm using JBoss 4.0.3SP1.

It`s a matter of cascade. Read EJB 3.0 persistence spec.
You can map wanted cascade values.

I missunderstood you. Basically it is not enabled by default (acessing child list should throw then LazyInitializationException if refering in page), but which entitymanager do you use? Seam for example fetches all lists.

Sorry I'm quite newbie with J2EE..
Where is entitymanager defined/configured?

I'm using EJB 2.x entity beans...
