Hi,

I have a question about the CompositeUserType.
Cosider the following situation:
In the tables in my DB I have a field that stores the ID of the user, that created the record. The information for that ID is in separate class.
If I create a CompositeUserType for that field, how can I pass the object, that holds the ID info to that CompositeUserType. Maybe somehow using the SessionImplementor parameter, passed to nullSafeGet/Set.


Regards,

The idea behind this is that I want to have a common type for fields with the same semantics. And most of these fields are system field.

the CompositeUserType creates that Object which contains the ID and returns it.
There's a good example in HiA.

For example in the "nullsafeget"-Method you won't return an "int" or "long" but a Object called "CreatorID" ...

OK, obviously I was not completely clear.
The idea in this case is mainly when I want to set a value to that field, but I have to get the value from external oblect. In this case the ID of the user. How can I pass this external object to the UserType ?

okay ... now i understand ...

I need something similar for Audit-Logs and i'm using a ThreadLocal to provide access to such information, but i'm setting the UserID before calling "session.save" ... but you can (of course) access it from your UserType, too.

This can be possible, but I'm not sure if it will work.
I have to check how Tomcat and Hibernate handle threads. Not to mention that I have Spring in between.
I can set the ThreadLocal variable in the user initial thread, when the user logs-in. I'm not sure in which thread Hibernate will execute. Is it the same, or it even can execute in the thread of another user ?
This can lead to very nasty problems.

it should be no problem ...
as far as i know Tomcat has a seperate Thread for each request ... therefore it's necessary to provide the information to each thread (request) ...
It works perfectly in combination with the HibernateSession ... so i think it should be no problem with a UserType ...

It's a long time ago i've used Spring, but i couldn't imagine that they're opening new threads ...

I'll try it anyway. Hope it works.
Thanks
