There is a lot of discussion about spring security with Vaadin FLow but I can find nothing for using Flow with JEE JAAS. Does anyone have this working or know how to set it up properly?
Any tutorial or references on getting this setup done?
I am not aware of one made for Vaadin 14, although there is not much specifics to Flow. Here is an old Vaadin 8 JAAS demo project https://github.com/mrts/vaadin-javaee-jaas-example I think it should be still be mostly valid, although you need to change Navigator → Router obviously.
