Yes- I am following that book as well, I have created a scheduler stuff as said in the book.
There are couples of problems with that.
I don’t see the newly created scheduler when creating a scheduler via the admin->scheduler (i have done repair and rebuild,scheduler rebuild).
Also I would like to know how to trigger the scheduler manually via browser or some other. I tried to trigger with browser url by entring the file path, when I do that it shows fatal error file not found(topic of question)
Well, the only connection is that if you want to trigger the scheduler job manually from a browser you’ll need to add it to the Entrypoints list and 'require’ing the entrypoint.php might help make available all the classes you need to include.
But I am not entirely sure of how to help you, I’m just looking for possible issues and solutions…
