Hi Björn,
Thanks for you answer. Our services are simple SOAP services implemented directly on PO. Technically some EJBs which are published as SOAP web services. These are ideal additions to our BPM processes and their start, intermediate events which are consumed as SOAP services also. This way all our UIs can communicate via SOAP with SAP backend.
Now if we switch to UI5 with the intention of consuming JSON and OData services, these EJBs should be published as REST services. Using SAP Mobile Platform to make OData services from the SOAP web services which are imlemented as EJB is kinda to much to be honest.
I've done a little bit research and came across to Jersey and Jackson libraries to deploy REST services on java. Standalone tests showed me that it is quite easy to apply these libraries. I'll try use this in PO / NWDS environment. I can post the results if anyone is also facing similar issues.
Regards,
