Service Builder does not create remote service method in interface

[Leo Venezia，修改在9 年前。]

Hi all
I'm trying to implement custom remote services. According to this, I should implement my method in XXXServiceImpl, then rerun Service Builder and then my method's signature will appear in XXXService.
But when after I have done this, nothing appears in XXXService.

Any help? Thank you so much.

What is the contents of your service.xml?

Does any error message appear?

Have you looked at the following section on remote services?

Thank you Jesse! Resolved.

I had created permission classes in a different way. The right way to create them was not explained in here:
