I've finished the demo 1.5 inbound connector that we were discussing in December last year. I'm back on that project now, so let me know how I can get it to you for testing. I've tested this with the Sun 1.4 RI, so it should meet the specs.
I'd also like to talk with out about the current deployment scenario. I'm not sure what I need to do to get my ear working with JBoss.
I've also attached the zip file to this message for other to try out.
I downloaded your example and hope to find some time soon to try deploying it!
There is a very simple jca 1.5 fake adapter in the testsuite, and I think it gets deployed. Look in the jca test directory
