I'm using WebSphere Application Server V8.5 Tools for Eclipse with the WebSphere Application Server ND V8.5 trial (NDTRIAL.agent.installer.win32.win32.x86_1.5.2000.20120223_0907).
There is IMO a documentation error in the tutorial "Create an EJB 3.1 application". The tutorial tells to create a data source by using the menu entry "Open WebSphere Application Server Deployment" from the menu group "Java EE". This menu entry does not exists (any more?).
The data source has to be created rather by using the administration console of the server.
