Cache Issue in distributed environment

Hi,
I am new on this mailing list and so it is my first message.

I am working on a project which is using OJB in a distributed environment.
The distributed issue is my problem ! I have read there are important points to respect in this case.

The first one is to use Sequence Manager. It's ok for me.

The second one is the locking issue. I am using the LockManagerRemoteImpl. So I think it is ok.

The last point is the cache issue. And this is the subject of this mail. Currently I am using ObjectCacheDefaultImpl. I know it is not suitable for distributed environment. That's why I'd like to use distributed cache.

I have heard about OS Cache but it requires a multicast network. It is not possible in my case.
I have heard about JCS too. Has anybody ever used it? I don't find information to configure it with OJB. Can anybody help me ?

Regards
