Sorry, I'm back with yet another question, as my NWDS offers nothing at all matching the documentations.
In the topic "Creating an Inside-Out Web Service from an Enterprise Java Bean " (http://help.sap.com/saphelp_nwpi71/helpdata/en/46/78955dcb496ef0e10000000a1553f6/content.htm) it says
2. In the Package Explorer of the Java perspective, open the project and select the EJB you have created. 3. From the context menu, choose Web Services ® Create Web Service. The Web Services wizard opens.
In the Java perspective I don't find "Web Services" at all in the Context menu.
I can't find similar help page (for creating inside-out webservices) when I searched in the Help Topics of my NWDS installation. This is very frustating, please advice.
