Importing a Web Service in my Web Dynpro Project

Hi;

I have created a project ear for my Web Services and Web Dynpro project. Now I would insert the web service in the web dynpro project, but I'm not able to do that. In my Web Dynpro, I go on "models" and click on "create model", then I have chosen "Import Web Service Model - DEPRECATED". In the "model package" is not shown the package. What do I have to do?
