[jboss-dev-forums] [Design of JCA on JBoss] - Re: JBAS-1437 RARMetaDataRepository

[adrian@jboss.org]

The whole 'guess the RAR' thing to me seems to be unnecessarily complicated and I am not quite sure of the point being that a JCA deployment MCF, ActivationSpec, AdminObject should always know to what RAR it belongs.


The basic feature is you just tell it the name. i.e. the ObjectName or name
in the microcontainer as a dependency.
e.g. rar-name in the -ds.xml or resource-adapter-name in jboss.xml

This doesn't require anything new and should just work like the old stuff.

But if you want to "guess" the rar to use from properties
e.g. Who implements the message listener for inbound (don't specify the rar name)
then you are going to need what I described above.

Stage (1) parsing - populate the rar repository
Stage (2) "real deployer" - resolve the dependency name from the properties
(once you know all the rar parsing has been done)
Stage (3) runtime - only start when the dependency exists (the rar is deployed)

The other stuff I described just turns stages 2 and 3 into one stage
with a custom dependency implementation.

To emulate the old stuff, stage 2 is a no-op. You've been told the dependency name
in the xml (or it is hardwired in the xslt :-).
