问题 I use AbstractRoutingDataSource to change data source dynamically and ThreadLocal to set up currentLookupKey. It works nice when I use only one data source per http request.

It appears that glassfish is maintaining a connection pool either way, so it's difficult to tell what the difference is. Thanks for any insight
