Hi
I am not touch any SCA yet, but I agree with Gert. You can treat Camel
as a single JAR file, it doesn't need any complex runtime to perform the
mediation work.
If you put it inside a SCA component , you do not worry about how to
embed it :).
Camel can run synchronously in most case, here is a wiki page[1] to show
how to leverage the asynchronous processing in Camel.

Vasil,
I'm not an SCA expert at all, but...
If you want to use Camel inside an SCA component, I think you should
be able to Tuscany's implementation.java or implementation.spring to
do this. If you hide the interaction with the other components behind
a Java interface as usual, it shouldn't matter if implementation is
Camel or any other Java code. You can choose to specify the Camel's
routes in a java class or a Spring configuration file and use that
inside your SCA component. Camel itself is just a JAR file you have
to include in your (not sure about the terminology either) SCA
composite. It shouldn't be too hard to have synchronous execution in
Camel -- just avoid the typical asynchronous concepts as seda:
endpoints and you should be fine there.
Suppose we would build a more specific implementation.camel for Apache
Camel, what additional features would you expect from that
implementation?

Hi Willem,
I was thinking for using the route and pattern description power of
Camel
inside an SCA component for a more declarative description of
integration
scenario between services to which this component refers. I could
have used
BPEL or BPMN for example but this is rather complex and
procedural-oriented,
while I need mainly transformation capabilities with simple conditions
(content-based router), split, agregate, filter, transform (XQuery for
example), etc. in more data-oriented scenario.
In this case the different connectivities (components) that Camel
provides
will not be needed as SCA cares for this and also anly synchronous
working
of the Camel engine will be used.
Do you think this is feasible usage of Camel?

Hi Vasil,
AFAIK , we do not have any plan to integrate Camel with SCA. But you
could share you ideas with us in the mail list :)

Hi,
Is there any integration between Camel and SCA planned. If yes, can
you
share some more information.
