Introduction
Another article about how to solve an error message as in the title of this article. Actually, the error message appear upon deploying a Java application to a Wildfly Application Server. The execution process is in a NetBeans IDE. So, the process is actually start by running the Java Application using the Run menu from the right click menu in the NetBeans IDE. When the process for building and compiling is finish, the rest is just deploying it to the Wildfly Application Server. The following is the output of the Output Tab which is part of NetBeans IDE :

Apparently, after searching the main cause of the error, the following is that line which exist inside the error output above :
WFLYCTL0186: Services which failed to start: service jboss.deployment.unit."apps.war".undertow-deployment: java.lang.RuntimeException: java.lang.RuntimeException: UT010039: Unknown authentication mechanism KEYCLOAK
Solution
Actually, the configuration for the keycloak feature exist in this Java Application. So, in order to make it running, one of the simple solution exist is by removing the keycloak configuration. For just an information, keycloak is an Open Source Identity and Access Management tool. It support for additinoal feature of the authentication to applications and it secure services with minimum effort. So, it will make it easy without having the application to deal for storing users or authenticating users. In general, keycloak provides user federation, strong authentication, user management, fine-grained authorization, and more. The main website for keycloak exist in this link. The following is the actual step for disabling the keycloak feature :
-
After searching the Java application or Java program, the keycloak configuration exist in the WEB-INF folder, specifically in the web.xml file as follows :
<login-config> <auth-method>KEYCLOAK</auth-method> <realm-name>this is ignored currently</realm-name> </login-config>
- Disable it by giving the comment sign as follows :
<!-- <login-config> <auth-method>KEYCLOAK</auth-method> <realm-name>this is ignored currently</realm-name> </login-config> -->
-
Finally, just run the Java Application or Java Program again once more. The main purpose is to be able to build, to compile and to deploy it once more to the Wildfly Application Server using the modificated ‘web.xml’. If there are no more error appear, the deployment process for the Java Application or Java Program in the Wildfly Application Server will be a success.
