Cannot see Town Scene after i run in Jmonkey SDK

Hi all,



i loaded the Town scene example in jmonkey project created in the SDK,

i am able to see the scene in the composer ,

i modified the main class loading the scene into a spatial and adding it

to the scene graph, just like it is explained in the tutorial,

but when i run the application i get the usual screen but nothing is loaded

inside, or at least nothing is shown, i took a look at the output console

and i get no errors.
