Yes thats possible, there's some doc about it at http://tuscany.apache.org/sca-java-bindingjms.html, specifically the bit on wireFormat.jmsObject/>. The old OSOA specs did not define a way to do this so Tuscany originally used a Tuscany specific attribute "messageProcessor" which is still supported in 1.x, later the OASIS specs did define a way to use this using the <wireformat> SCDL extension and Tuscany implemented that in the 1.x code but having it in the Tuscany SCDL namespace. I'm just bring up the JMS binding in the 2.x code now and it will be using the OASIS specs and namespaces. > 2.

There's been no interop testing and the OASIS JMS binding conformance tests aren't done yet though so you would really need to test this before relying on it right now though! > 3.

I guess the obvious way to do it would be to create a new binding extension to support <binding.mina>. I'd start but copying one of the existing Tuscany bindings (perhaps the RMI or JSONP binding as they're quite simple) and then changing to use Mina. If you'd like to try to work on that here at Tuscany I'm sure you'd get lots of help. ...ant
