You'll have to read the docs for this:
http://www.orocos.org/stable/documentation/rtt/v2.x/api/html/classRTT_1_...

There's no magic, only execute is called by the ExecutionEngine.

No. You'll have to put code in configureHook which interacts with your
service. There are helper functions for this in the TaskContext API.

If you connect to a clone, how can you get back to that port ? On the
other hand, you can create an input port in your service and connect
it in that way to an output port of your component and vice versa.
