To be honest, I have no idea... I fear only looking at source code can give you
an answer.

I think it should work as long as you replace Composable with Serviceable
interface and compose()
with service() method. However, if you write your own components from scratch I
would suggest to
write them as Spring beans instead of Avalon components.

What's exactly the exception thrown? This should work ok.

Third approach would be implementing your own servlet making WFS call and using
postable source but
it won't be much easier so I think writing transformer makes sense in this case.

No problem.
