Hi Satya,


without being able to look more deeply into your set-up: it sounds like a typical class-loading problem. The class and the interface seem to be present twice: one time inside your deployment, one time outside. Those classes are different for the JVM, so any PathBasedKeycloakConfigResolver in your deployment does not implement the “outside” interface KeycloakConfigResolver – and that’s why it fails.


Can you use <scope>provided</scope> with your Maven dependency? This way the library would probably not be in the deployment assembly and not be a problem.

Hi Team,


I have configured PathBasedKeycloakConfigResolver in my package: com.demo.util.


The context param has been set on web.xml






I deployed the application on Tomcat. I have registered the context.xml in meta-inf with the required adapter.


Tomcat lib directory has all the required keycloak jar files.


But PathBasedKeycloakConfigResolver never gets called on any request to the url.

One strange thing i find that in eclipse if I remove the maven dependency from deployment assembly(right click on project-> properties->deployment assembly) it works But if i put it back it fails. Maven dependency is a must.


After debugging   String configResolverClass = context.getServletContext().getInitParameter("keycloak.config.resolver"); of AbstractKeycloakAuthenticatorValve class


Got the following error: when PathBasedKeycloakConfigResolver  is being instantiated.


java.lang.ClassCastException: org.keycloak.example.PathBasedKeycloakConfigResolver cannot be cast to org.keycloak.adapters.KeycloakConfigResolver


But PathBasedKeycloakConfigResolver implements org.keycloak.adapters.KeycloakConfigResolver.
