It currently does not support a j2ee datasource, that is planned for post-GA. There are known issues with the connection pooling (3cpo) and hooking it up to use a datasource. The direction taken when writing the message store was to work as a totally standalone message persistence mechanism. Now that we have started packaging SARs I need to revisit this so that we can in fact hook into a datasource. It is possible, but I know it has problems. Since we can't introduce any code changes that would potentially break anything, I have held off on this till after the G.A.
