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

[Marek Posolda]

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
