I am using GWT in my current project and want to integrate OKTA. Currently, the challenge which I am facing is to call the Instance Method of Abstract Class in the GWT JSNI private native method. Can anyone help me with this? I am attaching the screenshots of the code snippte. The method okatIntegrate is written in an abstract class and in the same class I have also written one Simple Java Instance Method called test() which I am trying to call in okatIntegrate method which GWT Native method and written using JSNI standards, but not able to call. Please do the needful.TIA.
