[esb-dev] jca done (I think)

[Bill Burke]

Kurt, I don't understand what you mean with "can we use JCA within the 
ESB", can u elaborate?  I have a qa/junit test that uses the JMS adapter 
as a <jca-gateway>.  See the wiki on where it is.

Yes, you can use what I did to write gateways if that's what you're asking.
