Hi!
Are there any experiences with CDO used in an JEE environment running on
an application server (like WebSphere, JBoss)? Is it possible to use CDO
in a clustered environment?

We used to have a configuration property in the repository that, when switched on, lead to constant re-evaluation of the cached state in the repository against the actual backend. I vaguely remember that we've removed this mechanism at some point in the past because it was rarely used and caused bad performance and increased complexity in new functionalities that were added later. I will investigate this next week...

That would be great, especially if you report back your experiences ;-)
