[keycloak-user] JavaScript error: No Access-Control-Allow-Origin header is present...

Hi, as the subject said I got an error while sending a request to my keycloak server. I configured the following things: 1. External Keycloak server (runs on localhost:8180) a. Add realm b. Add client/application c. Add roles d. Add user + roles for this user e. Add Url to Web Origins (http://localhost:8080) 2. Wildfly 8 Server (runs on localhost:8080) a. Add keycloak adapter for wilrdfly 8 b. Add Security domain c. Add subsystem for keycloak (generated from keycloak admin console) 3. My Application a. Keycloak.json (generated from Keycloak admin console | "enable-cors" is set to true) b. Downloaded keycloak.js and added it to jsp/html pages c. Defined security-constraints and security-roles in web.xml I got the problem while trying to login to my application. Keycloak accepts my username and password and forwards me to the first site of my application. There I am using the keycloak.js to "login" and handle the different roles but within this workflow I got the following errors: 1. "XMLHttpRequest cannot load 'http://localhost:8180/auth/realms/TOMAMappingConfigurationService/tokens/access/codes'. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access. The response had HTTP status code 400. " 2. "XMLHttpRequest cannot load 'http://localhost:8180/auth/realms/TOMAMappingConfigurationService/account'. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access. The response had HTTP status code 403. " I hope you can help me. Kind regards, Lars
