Web Dynpro Model Generation for Application Services

[Former Member]

Hi Experts,

I'm currently experimenting with the new functionality provided by CE, but there is one thing that I can't seem to figure out. How does the new Web Dynpro model generation work with regards to CAF Application Services? I'm trying to call an application service from a web dynpro application, but it seems as if models are completely different from Netweaver 7.0. What type of model do I need to create? Do I have to expose the application services as web services?

I've tried creating an EJB model and then binding the model to the context, but I kept receiving null pointer exceptions when doing this and I'm not sure if this is the correct way to do this. Can anybody point me to some good documentation on Web Dynpro/CAF interaction in CE?

Thank you,

JP

Hi JP,

You are right, the CAF models are completely different in NW CE 7.1 compared to NW 7.0.

CAF Application Services in CE 7.1 are in fact EJBs. So the EJB model importer is the way to go.

Aah, okay, thanks Vladimir. It is starting to make sense.

I'll post again when I have "concrete issues"
