[keycloak-user] keycloak with embedded servlet containers

Are all the keycloak client adaptors meant to be deployed/installed in external servlet containers (not the embedded containers)?  We have some web apps that use embedded jetty.  The Jetty client adaptors that Keycloak supports are for external jetty containers, correct?  If we were to integrate keycloak with embedded jetty, how do we go about it? Please advise.  Thank you!
