[jboss-as7-dev] access to the ModelNodeRegistration during handling of an operation and during deployment

Hi All, I'm trying to resume here the discussion I had yesterday on IRC with Brian and Jesper. Basically JCA needs to have and already deployed instance of ResourceAdapter when adding its metrics and some operation. The reason for that is because some operation and metrics availability are known only at runtime, depending from RA status and/or vendor specific feature known only. Speaking from a Model point of view the basically issue is to have access to the ModelNodeRegistration when the RA instance is created and these runtime infos are available. There are 2 cases: 1) during handling ADD operation for a DataSource or special ResourceAdapter creation withour rar deployment (like hornetQ). 2) during foo.rar deployment chain We have also discussed where we can put these operation in the model tree. Also in this case there are two possible places: 1) at subsystem level for special no-deployment RA (DataSources and HornetQ atm). So we will obtain something like /subsystem=datasource/data-source=myDS and /subsystem=hq/ra 2) at DUP level /deployment=foo.rar Having this deployment support we can remove the current operation in /subsystem=resource-adapters that is redudant, referring the same RA (or better a subset of deployed ones) Hoping to have written all the matters discussed, feel free to integrate and/or ask. regards S.
