Calling Web Service Proxies - any examples?

After creating a "Web Service Client Proxy" Project using the supplied wizard in the NetWeaver Development Studio, we want to access ("consume") the deployed Web Service from our Webdynpro Project as well as from a normal J2EE Project.

We already read all the available information at help.sap.com ("Programming a Web Service Client Application" ? which doesn?t supply enough information in our case) as well as the supplied tutorials "Creating an Email Client Using Web Dynpro and Web Services" and "Using Car Rental Web Services with Web Dynpro" - which base on the use of the "Web Dynpro -> Models" wizard by using "Import Model from Web Service Definition"; unfortunately this functions seems not to be available in our current beta version (b4) anymore?

Our questions:

1) Where can we find more information about how to call our Web Service from a J2EE/Webdynpro Project calling the generated proxy directly?

2) Will the mentioned ?Import Model from Web Service Definition? function be available in future versions of NetWeaver Developer Studio again?

Any information on these topics would by very appreciated!

Kind regards,

Rob
