[jbosscache-dev] ComponentRegistry and TransactionManager

Interesting change from the ComponentRegistry has bitten me in the ass. The resolution of the TransactionManager used to take place in CacheImpl.create(), now it's happening via DefaultCacheFactory.bootstrap() -- i.e. as part of cache construction. This causes problems with the Hibernate integration, which injects the TM it knows about into the RuntimeConfig of the already-existing cache, before it calls create(). But that's too late -- the TransactionManagerFactory has already logged an error about a missing TM. A solution would be for Hibernate to get a Configuration first, inject the TM, and then build the cache. But the CacheManager API doesn't expose a good way to do that. An external caller can't modify the registered configurations. So: 1) What do you think about changing the ConfigurationRegistry API to allow some sort of updating of registered configurations? 2) In general, do you think it's a problem that we are now resolving things earlier in the process than we used to? Other users may also be doing things programatically after cache construction but before create/start. -- Brian Stansberry Lead, AS Clustering JBoss, a division of Red Hat brian.stansberry(a)redhat.com
