Hi Werner,
it's good to see the sample code for distrbuted caching, submitted a long time ago, has made it's way into CVS. Other users can test, review and extend the idea, if required.
I have been doing very little with Castor JDO for the past many weeks. We have finally rolled out our web apps to production using Castor JDO 0.9.7 with IBM WAS 5.1, with very few problems. We have had one issue with selecting UDB sequence values, but I think the problem stemmed from incorrect WAS and UDB configuration, rather than any bugs with the JDO sequence generators.
There has also been a push by other senior developers (and middle management) here to move towards Spring and Hibernate, the current favourites.
I would like to see the distributed caching code up and running, but I'm not sure how much time I will have for testing, nor how much access I will have to internal resources (app and database servers). I have picked up a few typos in the distributed cache samples, from my earlier submissions, so I will send at least those revisions.
I noticed comments from another JDO user regarding the lack of an "ehcache" implmentation, which I think is the default used by JBoss. The reflection API you have placed in the base cache class should make integration of other cache API fairly simple.
More later.
Tim.

Hi,
for those of you on the adventerous side of things, I just checked in support for distributed caches. As part of http://jira.codehaus.org/browse/CASTOR-1102, the following open source cache engines are now supported:
* JCS
* FKCache
* JCache
and on the commercial side,
* Coherence (Tangosol).
Some of these caches can be configured to run in a distributed (clustered) environment, allowing for the use of Castor JDO in a clustered J2EE application environment.
I'd personally welcome any feedback, and hope that this new feature will be useful in futuram.
Regards
Werner
