JavaFX NullPointer Exception Location is required - javafx

Question

I have an FXML file that is in a separate package. this answer is close but it is located in the same package.
the what confuses me is
Where is this path /src/resources/.fxml that some of the answers reference
How do I "copy" my fxml code into it.
This is the line of code that is getting me Nullpointerexception: Location is Required
root = FXMLLoader.load(getClass().getResource("IMSView/AppView.fxml"));
I have tried it with
root = FXMLLoader.load(getClass().getResource("/IMSView/AppView.fxml"));
Still get the same failure.
I am very new to java and I know I am doing something wrong. I could get this project to run when everything was in one file path. Now that I have added packages I cannot get the fxml to load.
Thanks for your time.
EDIT
I am using netbeans
The Main method ins in IMS.java The FXML that I want to load is in a package called IMSview and is name AppView.fxml
