Does JBoss support message inflow (see the last bullet on page 19 of the draft JCA 1.5 specification here ftp://ftp.java.sun.com/pub/spec/j2ee_connector/1_5-pfd/j2ee_connector-1_5-pfd-spec.pdf )? Message inflow is explained in depth in chapter 12 of that draft. I don't think this was part of 1.0, and I think it was initially slated for 2.0. From chapter 12:
"This chapter specifies a standard, generic contract between an application server and a resource
adapter that allows a resource adapter to asynchronously deliver messages to message
endpoints residing in the application server independent of the specific messaging style, messaging
semantics and messaging infrastructure used to deliver messages.(...)"
If JBoss doesn't support this in a spec-compliant way -- is there a) an alternative, tested, but non-standard way or b) would it be a small matter to hack in support for this feature.
I'm working on it. Note that the jca 1.5 spec is by no means approved yet.
We already have a non-spec way of handling this in the jms jca adapter. That might give you some hints if you want something sooner.
