Hi Armin,

actually I though the same, the ObjectCachePerBrokerImpl should do the job.
I was just wondering where the code has gone in the EmptyImpl, because the
website says it supports circular references.

Thanks
Lasse

 Hi,

 I'm using RC5 and saw, that the class is empty. Unlike in RC4 where there
 is code in this class. I checked the CVS and since version 1.9 it's
empty.
 Whats the reason for this and are there any recommendations how to handle
 circular references in a non-cached environment?

You can use ObjectCachePerBrokerImpl. This class is similar to the old
version of ObjectCacheEmptyImpl, but only clear cache on PB.close and
PB.rollback.

I removed support for cicular references in ObjectCacheEmptyImpl,
because all docs said that this class is a really noop-impl and does not
support circular references.

Should I add support for cicular references again to this class?

regards,
Armin

Hello Edson,

your reply is not very helpful, but anyway, good for you if that 1 sec
approach works for you.
Turn the cache (EmptyImpl) of and you'll see that some OJB testcases won't
run as expected.

Regards
Lasse

Well, it's boring get beginners programmers around me sayind hey, OJB
doesn't work!!!, and all times I need to tell them that is just because
they are making a bad modelling desing making two-way navigational
references in all objects (kidding)...

I think it's not an priority, because it can be deal with
per-class-descriptor way. In the specific classes the problem occur, I make
a very-really-short object-cache (something like 1000ms solved at all).

I'm just thinking about using a ObjectCache with 1 sec. as default to all
classes, and set Empty only when strictly necessary. But it could be done
only after june, where our app will be completelly stabilized

Thanks,

Edson Richter
