I am following the book and on the page http://symfony.com/doc/current/book/doctrine.html

While following the book I am trying to work on relationship of product and category table and doctrine generate command is giving me following error.

php app/console doctrine:generate:entities Acme
Generating entities for namespace "Acme"



  [RuntimeException]                                      
  Namespace "Acme" does not contain any mapped entities.  



doctrine:generate:entities [--path="..."] [--no-backup] name

Thx

php symfony doctrine
