Hi Sebastian.
We have tested some of the provided samples, but not all yet.
So, we indeed have to test all the samples we provide with the Tuscany
configuration and adapt them if necessary.
I have also checked that the client application provided in this sample
to test it does not work and throws the same exceptions.
We defintely have to correct this example.
Thanks for the feedback.
Vincent.

Hi,
I found a solution for resolving the warnings and with the solution I
run the example properly.
My solution:
I changed two files, BillServiceComposite.composite, and
RestaurantComposite.composite (see them at last part).
The basic problem was that the Composite have the following service
(*1) <sca:service name="BillService"
promote="BillServiceComponent/BillService"/>
in where , I think that promoting was enough (please correct me if it
is wrong), because in BillServiceComponent is defined:
<sca:service name="BillService">
<sca:interface.java
interface="restaurant_implemcomposite.api.BillService"/>
</sca:service>
Mi solution was redefine sca:service (*1) tag as follows:
<sca:service name="BillService"
promote="BillServiceComponent/BillService">
<sca:interface.java
interface="restaurant_implemcomposite.api.BillService"/>
</sca:service>
In RestaurantComposite I redefine:
<sca:service name="RestaurantService"
promote="RestaurantServiceComponent/RestaurantService"/>
for:
<sca:service name="RestaurantService"
promote="RestaurantServiceComponent/RestaurantService">
<sca:interface.java
interface="restaurant_implemcomposite.api.RestaurantService"/>
</sca:service>
With this changes the project works correctly.
Someone in this mail list, can tell me if it is nonexistent
functionally in Tuscany 1.4 version or is my interpretation error of OSOA
specification? have Any suggestion?
Thanks,
Sebastián.

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

Hi Natasha, Sebastian.
FYI, the last build version of SCA Tools is available here :
http://download.eclipse.org/stp/sca/last/
It is not the official Eclipse update site. This is the address where we
regularly release custom builds of the SCA tools
