This starts web2py, as does my code above, but if I close it, it disappears from the launcher again. The mentioned link didn't help me.

@Karel Hello, no I have no Icon in the dash. Web2py is resting in my home directory ('~/web2py/web2py.py'). I can start it via the terminal: 'python web2py/web2py.py'. If I do so the icon appears in the launcher but if I lock it there it will disappear as soon as I close web2py. Locking icons for icons I see in the Dash (like the terminal app) works.
