I'm trying to write an addition to the database in the controller for the entity, but for some reason ejbFacade == null. Why?

Question

Java

I am developing a web application in which I use templates. NetBeans development environment - Following the example of the jsf and classes created by it, I write the application itself. I am trying to write an addition to the database in the controller for the entity, but for some reason ejbFacade == null, and accordingly I cannot do something with it. But the problem is that in the template I did not see that the field was somehow initialized.
PS Perhaps confusedly explained, but I really need help.

Answer 1

@EJB
private entity.UsermyFacade ejbFacade;
the ejbFacade variable is initialized with the EJB annotation. In essence, the application server looks for a class that implements the UsermyFacade interface, creates an instance of it, and associates it with ejbFacade through a proxy

Answer 2

maybe so

Answer 3
