[jboss-as7-dev] Binding MDBs to resource adapters by configuration

[Jaikiran Pai]

Just a FYI - Right now, there's a way to configure the resource-adapter 
used by the MDBs via the standalone.xml/domain.xml. But that then 
applies to all MDBs deployed on that server. You can do it as follows:

<!-- Default MDB configurations -->
<mdb>
<resource-adapter-ref resource-adapter-name="ra-name-of-your-choice"/>
...

But like you say, there are plans to allow it to be specified at per MDB 
or even a per deployment (applies to all MDBs in that deployment) via 
the jboss-ejb3.xml. Carlo has been working on the jboss-ejb3.xml parts, 
so he'll know if we already have some code to support this. If not, we 
are welcome to contributions.

P.S: We are usually on #jboss-as7 irc.freenode.net IRC channel if you 
want to have a chat about how to proceed on the implementation.
