keycloakwildfly-10

NoClassDefFoundError: org/keycloak/KeycloakPrincipal

I am getting following exception while deploying ear in WildFly 10. Apapter is installed so no jars included in ear & no dependencies set.

Caused by: java.lang.NoClassDefFoundError: org/keycloak/KeycloakPrincipal Caused by: java.lang.ClassNotFoundException: org.keycloak.KeycloakPrincipal from [Module \"deployment.app.ear.appEJB.jar:main\" from Service Module Loader]"}, "WFLYCTL0412: Required services that are not installed:" => [ "jboss.undertow.deployment.default-server.default-host./App" ]

This issue comes only for classes in appEJB.jar. The classes in appWEB.war has no dependency issue. Here is my subsystem conf:

             <subsystem xmlns="urn:jboss:domain:keycloak:1.1">
                <secure-deployment name="appWEB.war">
                    <realm>demo</realm>
                    <resource>app</resource>
                    <use-resource-role-mappings>true</use-resource-role-mappings>
                    <public-client>true</public-client>
                    <auth-server-url>http://localhost:8180/auth</auth-server-url>
                    <ssl-required>EXTERNAL</ssl-required>
                    <principal-attribute>preferred_username</principal-attribute>
                </secure-deployment>
            </subsystem>

Is there any other way to configure ear deployment in subsystem so that ejb.jar also get Keycloak libraries implicitly?

Solution

  • Issue fixed when I set Keycloak modules dependency for ejb.jar in jboss deployment descriptor.

    <module name="org.keycloak.keycloak-adapter-spi"/>
<module name="org.keycloak.keycloak-adapter-core"/>
<module name="org.keycloak.keycloak-common"/>
<module name="org.keycloak.keycloak-core"/>
