I got your tutorial working. But when running it from ghci an exception 

*** Exception: _local/<interactive>_state\current-0000000000: 
openBinaryFile: invalid argument (Invalid argument)

But I found a way to fix this: replace

   runserver 5001


   withProgName "happs-tutorial" $ runserver 5001
