Thanks for your answer, chris! You gave some useful hints that solved
some other issues in my code;)
Anyway, my problem unfortunately remains. And the more I get into it
I think it is a really not expected behavior - maybe a java bug?
Once again, my scenario: I realize the following (very simple) ER model:
Hotel (1) --A-- (*) Room (*) --B-- (*) Feature
The cascade type is set to ALL, fetch is Eager. Also I ensured that
all Entities are stored right into the database. So I think the code
is just fine.
I instanciate just one (!) hotel pojo (with some room objects which
themselves keep some references to some Feature objects) on the
client side. Then I perform a jndi lookup to retrieve the (so called)
AdminFacade and just call the createHotel(Hotel) method while setting
the earlier created hotel as parameter. When calling this method
remotely the memory on the SERVER SIDE (at least I think so, see full
stack trace below), exceeds the limit of even 1.5gb heap space!
The problem: I noticed the following strange behavior depending on
how I realize the relationships (which causes the highly increased
memory consumption and I think therefor a StreamCorruptionException).
I use a HashMap<Int, Room> for realizing relationship A. For
relationship B I use
a) an Array Feature[]
b) a LinkedList<Feature> (also tried HashSet)
In case a) everything works fine, in case b) the memory explodes
while Marshalling (again I think so) the one Hotel pojo.
So, as you hopefully can see, my problem is not related to any
"mapping objects to databases" or to any persistence issues at all.
The problem occures while serializing data through RMI and (?) CORBA.
It seems very strange to me that using one "level" of 1:n
relationships (A) works but any deeper level (like B) of 1:n
relationships (realized via Collections) results in gigabytes of
memory usage!! Looks to me like an endless loop or what so ever.
Can you follow my thoughts or are there any tweaks on marshallign/
serialization I could check out to get behind it?
Thanks again for your time.
With best Regards,
Vivian
