Multithreaded environment getting exceptions
wrote...
Hi,
that's just standard transactional behaviour :-) You are not allowed to change the same items in 2 sessions in parallel, and there's no implicit ordering when this problem is detected; but the servlet just returns the raw exception back to you. If you need to deal with such situations (e.g it will happen during standard operation and is suppossed to work), you probably need to handle this situation, either by implementing your own servlet (which just implements retries or a higher-level locking based on the path), or you deal with it in your browser application (javascript).
kind regards,
Jörg
Hi Jorg,
Thanks for your reply. I am stress testing the system and basically, i am opening an admin session as i need to do group and user related operations. All this happens within a method and the variables have all got a local scope (and they are obviously not thread safe) . After i am done creating users and adding them to groups,i need to further create few other nodes which are user related and finally i save the session. All this done within a method which further calls other methods to complete the task.
In case i receive this generic exception, i can rollback the transaction but stress testing is throwing a lot of these issues and client won't accept a lot of people being shown error screens in case of these issues.
I am not particularly sure of what you meant by (which just implements retries or a higher-level locking based on the path).
Thanks.
