I've been following keycloak guide, but I'm facing the below exception.

I'm trying to secure a WAR that is inside of an EAR, I've tried to add below two dependencies in my pom.xml.

What am I missing?

Wildfly version: 10.0.0.Final

Keycloak version: 1.9.0.CR1

Dependencies (tried in EAR and in WAR, no luck):

<groupId>org.keycloak</groupId>

<artifactId>keycloak-core</artifactId>

<scope>provided</scope>

</dependency>

<groupId>org.keycloak</groupId>

<artifactId>keycloak-adapter-core</artifactId>

<scope>provided</scope>

</dependency>

Subsystem configuration:

<secure-deployment name="Test-web-1.0-SNAPSHOT.war">

<realm>TestRealm</realm>

<resource>test-resource</resource>

<realm-public-key>MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAmpxbZQMAf2NPcWCbdVWfu3JKEZ5PHuL+a5JTzyuln/wXpfhGPyCDS8rYDj2tf5lA8WQYoV8M5ip3DbCdL43wsW8/oJM/UOKn7mwy2x0OdW40bw1c8b1D6FveliIXwtovyw0EGCFn67qLdtHPLAlVvv5UXPIPFCakzdx1xS/6zgZ1uF2fzwLZpLh21M9XYNHQk6ui047+13Uf5H5yYQNLin8WluZ4JLfO8teVV9ARTqezVoZ5/+SNH4Mw+N1i7sGr13mzl51XvpFmm10Yx0dNiuy+WPA9xv1eNWcWgQWXxCEzDBenn59pmZ9JnTpoOqvZknmBGqyQPDqN9tJIWnWZKQIDAQAB</realm-public-key>
