Hi Vlasta,
I think I have had them in "jboss-deployment-structure"

[/opt/jboss/keycloak/modules/system/layers/keycloak/org/keycloak/keycloak-server-subsystem/main/server-war/WEB-INF/ jboss-deployment-structure]
<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="org.keycloak.keycloak-server-subsystem.dependencies"/>
            <!-- Kie requires access to kie.conf files from META-INF -->
            <module name="org.kie">
                <imports>
                    <include path="META-INF"/>
                </imports>
            </module>
        </dependencies>
        <exclude-subsystems>
            <subsystem name="webservices"/>
            <subsystem name="weld"/>
        </exclude-subsystems>
   </deployment>
</jboss-deployment-structure>

[/opt/jboss/keycloak/modules/system/layers/keycloak/org/keycloak/keycloak-server-subsystem/dependencies/main/module.xml]
<module name="org.keycloak.keycloak-server-subsystem.dependencies" xmlns="urn:jboss:module:1.1">

    <dependencies>

Hey,

I think you could try to add dependency to the keycloak-services, see https://docs.jboss.org/author/display/WFLY/Class+Loading+in+WildFly section JBoss Deployment Structure File.

Hi Experts,



When I follow https://www.keycloak.org/docs/latest/server_development/index.html#packaging-the-action step by step to do customize the validation in keycloak. After I throw my jar into standalone/deployment, it creates a deployed file and the log shows the jar is deployed.  I can found my execution in keycloak admin console which shows in the screen shot below. But when it comes to register page, after I click register button with my filled content I got exception in keycloak log file. I also checked `standalone.xml` and `jboss-deployment-structure.xml` which seems fine too which means it include "keycloak-services-4.7.0.Final.jar". I don't find any useful information in the search. So could anyone help to have a look please?



Keycloak  version:

    compile group: 'org.keycloak', name: 'keycloak-core', version: '4.7.0.Final'

    compile group: 'org.keycloak', name: 'keycloak-server-spi', version: '4.7.0.Final'

    compile group: 'org.keycloak', name: 'keycloak-server-spi-private', version: '4.7.0.Final'

    compile group: 'org.keycloak', name: 'keycloak-services', version: '4.7.0.Final'
