Gert,

Correct.  What we've been discussing most recently is the SCA
translation layer that would convert the lingo as you described.  I
wouldn't even call this a component.

The second approach I believe also works (creating an SCA SE), but I
think we believe the SCA translation layer would provide the most
value.

FWIW, I think there is a third approach: to create a a SCA component
implementation specification for JBI. (e.g. introduce an
implementation.jbi element into SCA contributions)

I tried to outline the different strategies here:

L.S.,


Just trying to grasp what the problem/question is...

So, if I understand correctly, the servicemix-sca component will be
somewhat different from any other JBI component.  We won't be building
an SCA container as a service engine (like you would do for e.g. EJBs),
but rather build some kind of support for deploying SCA artifacts
directly on ServiceMix.  In order to do this, the 'metadata' that is
available in the SCA artifact (sorry for not using the correct
terminology, definitely need to read up on SCA) needs to be translated
into JBI lingo, e.g. if an SCA component with implementation.bpel is
being deployed, it needs to be translated into a service unit, targeted
at the Ode JBI SE?

We are looking at the design some kind of SCADeploymentService, with
translation plugins to enable translation from e.g. an SCA
(implementation.bpel) -> ODE JBI SU... right?
