Hi Max please i don't get it ...........i don't think i need a course on concurrency.there is a problem i believe the hibernate community is not addressing properly.and it has to do with the one to many mapping and the reverse wich is many to one. i have read from other places and many people seem to be talking about it.the Error that keeps coming is :COULD NOT SYNCHRONISE DATABASE STATE WITH SESSION.
please if you can help i would appreciate it but please i think your reply to me is strong language thank you.

Well if you've got a specific problem, post the details and we'll try to help. Solving your synchronisation problems upfront without any information is a tall order.

pkkamos,
do you really think there is a real problem with bidirectionnal associations? i think what you must do is:
1- read reference doc and hibernate in action
2- read it again
3- read wiki about bidirectionnal associations
4- search the forum with

Quote:

COULD NOT SYNCHRONISE DATABASE STATE WITH SESSION.

5- debug your apps and ask yourself if you have a good session management
6- if you're not sure, go to 1- and 2- again ;))
7- then, and only then go back here and read the rules, post some mapping files, some java code, and short stacktrace.

Then, someone will help you, every friend on this forum that respect the rules get help, no problem.

Regard,

Hi pkkamos,

My response were merely a joke answer to a question that was unanswerable since you provided NO information whatsoever besides the word synchronization which has a very broad definition.

But anyway - follow Anthony's advice its the least you can do.

Furthermore the log output and stack trace should actually tell you very precise why the error occurs.
