[keycloak-user] java.lang.NoClassDefFoundError in a customized Reset password authentication flow

[GESLIN Fabrice]

Thanks for the answer Marek but unfortunately adding the jboss-deployment-structure.xml to the META-INF of our jar doesn't solve the problem.

FYI, we've previously implemented a custom Username Password Form authenticator that imports and uses some classes from  the keycloak-services module and we didn't have to explicitly specify the dependencies in an xml file.

Is there anything special with the ResetCredentialsActionToken class or its package ?

Regards,

Fabrice Geslin

Hi,

I think this error is due the fact that file jboss-deployment-structure.xml is either missing or it is missing the references to needed jboss module with the class org/keycloak/authentication/actiontoken/resetcred/ResetCredentialsActionToken. 
Which I think is the module "org.keycloak.keycloak-services" .

For some more reference, see for example this quickstart https://github.com/keycloak/keycloak-quickstarts/tree/latest/action-token-authenticator
and especially this file in it
https://github.com/keycloak/keycloak-quickstarts/blob/latest/action-token-authenticator/src/main/webapp/WEB-INF/jboss-deployment-structure.xml
.

Hope this helps,
Marek
