RE: DB Localization

I've solved my problem. I now optionally set a locale object on my base DAO class. If the locale is not null, I add a PBLifeCycleListener to add the locale to my VO object after a lookup. Then in my VO object, I have functions like: public String getName() { String returnValue = !!!LOCALE

Re: [PB API] concurrency problems

Hi Sven, I don't know if your problem rely on a concurrency problem. Between rc4 and rc5 I changed handling of DB resources in RsIterator class. Now OJB is very strict in closing used resources. All resources will be released when - PB instance was closed - PB commit call is done - PB abort

Re: [PB API] concurrency problems

Hi Armin, I wrote a test for this, now. Unfortunately I wrote it against my application, because I haven't installed the OJB test suite yet ;( The test starts n threads. Each thread creates a PersistentBroker, retrieves 4 instances of an entity and then checks some references for each entity.

Status on 1.0 release?

I haven't seen any talk recently on the list about the progress for when the 1.0 release will be labeled. Is there a plan now for when that might happen? Are there certain bugs outstanding that are keeping this from happening that we can help chip into fix? I will admit my curiosity is for a

I just changed ObjectCacheClass from DefaultImpl to EmptyImpl. Without caching the test doesn't fail. I think this happens because the threads don't have to share the objects in this case. Sven Sven Efftinge wrote: Hi Armin, I wrote a test for this, now. Unfortunately I wrote it against my

Hi, while running the OJB testcases I got a lot of circular problems when using the ObjectCacheEmptyImpl (no Cache). 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

Re: [PB API] concurrency problems

Hi Armin, I just figured out that you were right. The problem I had occured because I tried to access not yet loaded proxy references after closing the broker. But what happens in my test? Does this occur because OJB sets auto-retrieve to false sometimes? Ho can we handle such a behaviour?

RE: [PB API] concurrency problems

I realized about 5 minutes after I sent this that it *would* in fact cause circular reference problems. So, that wouldn't work. This is a pretty tricky issue. The other solution I had would be to 'soft' commit the parent object to the cache until the entire map below it is materialized, and then
