Re: [keycloak-user] Use keycloak classes from a custom Authenticator: NoClassDefFoundError
Hi,
I do not know your exact project setup but you have to declare any dependencies as wildfly
isolates classloaders.
As AbstractIdpAuthenticator is included in the keycloak-services module, you can use this
In the jar's META-INF/MANIFEST.MF:
Dependencies: org.keycloak.keycloak-services
Maybe additional Modules have to be included as well.
See appropriate documentation of how to do this in your favourite build tool.
See http://docs.wildfly.org/17/Developer_Guide.html#ear-class-loading (applies to
keycloak's jar mechanism as well)
Best
Daniel

Betreff: [keycloak-user] Use keycloak classes from a custom Authenticator:
NoClassDefFoundError
Hi everyone,
I want to write a custom Authenticator that borrow code from AbstractIdpAuthenticator (or
better, extends it).
However, as soon as my authenticator attempts to load a class from the keycloak-services
package, I get a NoClassDefFoundError. For example:
08:24:53,608 ERROR [org.keycloak.services.error.KeycloakErrorHandler]
(default task-6) Uncaught server error: java.lang.NoClassDefFoundError:
org/keycloak/authentication/authenticators/broker/util/SerializedBrokeredIdentityContext
I used the authenticator example provided in the examples directory as a base for writing
the pom.xml file.
Should I be able to use or extend keycloak classes from within my provider (packaged as a
jar, I also tried wildfly:deploy)?
If so, what am I missing?
I also posted a question on stackoverflow, you may find some relevant detail in it:

Thanks,
Christophe
