Abdeslam, your problem is that camel cannot send messages to COM components because there is no camel component capable of doing that and I am not aware of any plans for implementing one anytime soon.
It looks like you only have a couple of options:
1. Implement a camel-jinterop component yourself that will have to be able to instantiate a dcom endpoint (you'll have to come up with your own encoding, something like from("dcom:")... and convert a message body and headers into the arguments for the dcom rpc call. I don't think it's too hard to implement that, but it may be a bit harder to make it generic.
2. Have your DCOM object expose its functionality over some other protocol already supported by camel, like http (not sure if feasible).
I hope this helps
