Using KeyCloak 2.5.4 and Wildfly 10.1.0
I am attempting to create a JSF component that involves Keycloak. I am getting this
exception:
java.lang.ClassCastException: org.keycloak.KeycloakPrincipal cannot be cast to
org.keycloak.KeycloakPrincipal
Below is the line of code that throws the exception.
public void encodeBegin(FacesContext context) {
..........
KeycloakPrincipal<KeycloakSecurityContext> kp =
(KeycloakPrincipal<KeycloakSecurityContext>)
context.getExternalContext().getUserPrincipal();
..........
}
Funny thing is this. The exception is only thrown when the JSF Component is in a separate
jar and then added to the project. If I put the code in question directly in the project,
it doesn't throw the exception.
Can anyone help me with this?
7:06 p.m.
What do you mean "separate jar"? A jar in the WAR?

Yes. But it is an Ear file instead of a War file. A separate jar in an Ear file.

This sounds like you're ending up with duplicate keycloak libraries on your
classpath. Did you include the keycloak client subsystem? Are the
keycloak libraries also ending up in your EAR or WAR?

The keycloak libraries are in my subsystem. When I include Keycloak jars in my EAR, I get
the ClassCastException. When I don't include the Keycloak jars in my EAR, I get a
java.lang.NoClassDefFoundError: org/keycloak/KeycloakPrincipal exception
Here is my Dockerfile I use as my base image. It has the Keycloak adapter in it.

When I change the project to not include the Keycloak jars and to build as a WAR file, it
works great. Not sure why it doesn't work as an EAR file without the Keycloak jars.
