When retrieving reference to the Object Store, Narayana can do a named bean lookup; more specifically, the store manager searches for the bean named communicationStore.

Part of the initStore procedure referenced in the link is class loading. As can be decucted from the code, when we try to classload a named bean, the implementation looks for a very specific constructor containing exactly one parameter and the type of such parameter must end with EnvironmentBean.

Problem arises (as already noted in the quickstart ArjunaJTA/object_store) when we wish to use HornetqObjectStoreAdaptor as our communication store as no such constructor currently exists.
