Use webservice models from another DC

Question

Hi Experts,
I am trying to develope a Web Dynpro Java application according to the best practice tutorials from sdn.
So firstly I created a DC (model DC) in which I created the required models (adaptive rfc and webservice). Then I added these models to the public part of the DC.
In the next step I created another DC, the "model component DC", and added the models from the public parts of the "model DC" to the Dependencies of this DC. After this I added the models to the "Used Models" folder of the "model component DC". Till this point everything seems to work - every model (rfc and webservice) appears under "Used Models". But when I try to create a service controller for the models I only can choose between the rfc models - the webservice models are not available. Even trying to code a service controller on my own leads to syntax errors.
When I add the web service models under the "Models" folder I can select the models for a service controller without problems. But as this project is for my thesis I want to create this application according to the best practices.
Hope anybody can help me with this.
Thanks and regards,
Michael

Answer 1

Personally, i would
create a seperate DCs for all the webservices,
create some plain java EJBs in src folder,
write certain methods to consume these webservices
and then create public parts of those EJBs.
consume the public parts.
It becomes easier to maintain and since one w/s may be consumed in multiple DCs, it saves me time to import reimport the model in all Dcs and make changes in only one EJB instead of all places where i consume it.
I am using this approach.
