[keycloak-user] Could not obtain configuration from server

Hi everyone, I am having troubles obtaining access token for my Java EE REST service from Keycloak. I have started Keycloak server at *http://localhost <http://localhost>*, and I can access the admin console at *http://localhost:8081/auth/admin/master/console/#/realms/demo <http://localhost:8081/auth/admin/master/console/#/realms/demo>.* Next, I created a new realm "demo" and registered my REST service there. I've copied the generated *keycloak.json *to the WEB-INF of my service and added what was needed to web.xml. This successfully protected my endpoint. My REST service is up and running on *http://localhost:8080/ <http://localhost:8080/>.* However, now I want to set up a client that would be authorized to access the protected endpoint. The client is running at *http://localhost:9080 <http://localhost:9080>;. *Again, it's a Java EE REST service that talks to the protected service. I registered it as *OAuth Client* in the admin console and again copied the *keycloak.json* to the resources of my app. I am trying to obtain the access token like this: AuthzClient authz = AuthzClient.create(); AccessTokenResponse tokenResponse = authzClient.obtainAccessToken(); This results in the following error: java.lang.RuntimeException: Could not obtain configuration from server [ http://localhost:8081/auth/realms/demo/.well-known/uma-configuration].<... <div id="stack">at org.keycloak.authorization.client.AuthzClient.<init>(AuthzClient.java:92)<br>at org.keycloak.authorization.client.AuthzClient.create(AuthzClient.java:60)<br>at org.keycloak.authorization.client.AuthzClient.create(AuthzClient.java:53)<br>at hr.assecosee.three_ds_2.risk.services.ProxyServiceImpl.invokeRiskLevelApi(ProxyServiceImpl.java:28)<br>at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)<br>at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)<br>at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)<br>at java.lang.reflect.Method.invoke(Method.java:498)<br>at com.ibm.ejs.container.EJSContainer.invokeProceed(EJSContainer.java:5316)<br>... 16 more<br> </div>Caused by: org.keycloak.authorization.client.util.HttpResponseException: Unexpected response from server: 404 / Not Found<br> I posted a question about it on StackOverflow too: https://stackoverflow.com/questions/49534589/404-not-found-while-requesti... Is there something I am missing?
