[keycloak-user] Package custom rest endpoint in EAR

According to the documentation it should be possible to drop an .ear file in the standslone/deployment folder. Based on this, what would one need to do to package the domain-extension example ( https://github.com/keycloak/keycloak/tree/2.5.x/examples/providers/domain...) in a valid ear? Anyone with experience in successfully deploying ear archives that can share some examples? Note: I'm using keycloak 2.5.4 Br Ulrik
