Hi,

i am trying to get the 2nd level cache working properly with different kind of relations. According to what i've
read the following is true:

OneToMany:
Changes have to be done on both sides (setParent on the many side and collection.add on the one side). If
something deleted by Cascade.DELETE i have to evict all affected collections from the cache.

ManyToMany:
I don't know.

Could anybody tell me wether the OneToMany part is correct and where i can find information according
to ManyToMany relations. The best thing would be a page with all necessary information to cache and all
relation types.

Thanks a lot!

Yours

Argh... i totally get crazy with this.
Do i really have to manage the ManyToMany relation on both sides? Even though i tell hibernate using mappedBy what
the "main" side is? Do i really have to manage Cascade.DELETE manually in order to clear all related caches? And this
for maybe hundreds of beans and dozens of relations?

This would probably turn the 2nd level cache into a very questionable thing :(
