I am looking at linking our legacy app to Keycloak.

Currently it is a bespoke jetty server, that only serves our war files.
The security.xml is set in config of the server directory.
I have taken the example setting file from https://keycloak.gitbooks.io/securing-client-applications-guide/content/topics/oidc/java/spring-security-adapter.html

I can see this loading keycloak's spring adapter.
It fails when searching for Keycloak.json.

I was hoping to be able to drop the Keycloak.json file in the config directory.

Hope you can be of assistance. Please feel free to ask if I have missed any key information.
I am trying to get up to speed on both KeyCloak and SpringSecurity as I am a C++ programmer at heart.
