Hi Vincent,
thanks for your help, I installed SCA Tools from
http://download.eclipse.org/stp/sca/last/ and works fine, good work!
Now I tried with one of the examples that is in File -> New -> Example (SCA
Examples), more precisely
Restaurant - Composite. The right diagram shows how all components works
together. In SCA Perspective I opened RestaurantComposite.composite_diagram
and I saw the nice picture, but when I Run the example (over the class Test
running it as Java Application or Over the Composite RestaurantComposite
running it as SCA Application) I have the the exception:
.

What I'm doing wrong? I always get the following:
WARNING: Component implementation not found: Component =
BillServiceComposite Uri = null.
Is this example working? If exist any web or tutorial explaining this basics
thing I'll apreciate it!
Thanks for your help,
Regards,
Sebastián
