Antwort: Re: ObjectCacheEmptyImpl.java
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.

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.

Re: ObjectCacheEmptyImpl.java
I have same problem. Actually, I'm using a per-object cache where the problem is detected. It's not a solution, but a workaround. Edson Richter --- Outgoing mail is certified Virus Free.
