RE : [mdr-dev] RE : [mdr-dev] RE : [Fwd: Re: [mdr-dev] JDBC persistence]

I think it could make sense. Let suppose we modify MDR's state because we
have create a new objet. This may correspond to an application state which
must persistent. Both states must committed together : the transaction is a
multi-database transaction. In this case, Jboss transaction manager will
ensure atomicity and soundness.

PS : I need that in my application that integrates both MDR and a RDBMS. I
had to write a may to be sure that the state is sound. But because I cannot
integrate completly Jboss and MDR as for JDBC RDBMS, my solution is weak and
somewhat complicated.

Oh, I see what you mean.  But I don't think it's possible to do that 
purely at the persistence level.  The reason is that the higher levels 
of MDR maintain their own transactional state as well, so they would 
have to participate in the transaction management.  Does that make sense?
