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

Wed Apr 3 03:39:28 EDT 2019

Hi,

After having added a few more dependencies in the jboss-deployment-structure.xml, it works.

Thank you for your kind and appreciated help Marek.

Regards,

Fabrice Geslin

No, there is nothing special in this class. Just maybe that it inherits from some classes/interfaces from other keycloak modules. So maybe you need to add few more modules like keycloak-server-spi and keycloak-server-spi-private.

If you still see issues, I suggest to try for example:

- Deploy as a WAR instead of JAR (Same like the quickstart I pointed is
doing)
- Deploy your JAR as a module rather than the file directly deployed in standalone/deployments
