[keycloak-user] Activating events-listener SPI on keycloak startup

Hello, I implemented my own events-listener SPI based on the documentation example (https://keycloak.gitbooks.io/documentation/server_development/topics/prov...). Now I want to activate the event listener. I can do so in the admin console (Events->Config) but I would like to activate it automatically on startup. I tried modifying the standalone.xml but it did not help, probably I am missing something. Could you please help me on how to activate the event listener implemented in the SPI on startup of keycloak? Regards, Stepan Vanecek
