You shouldn't have keycloak and httpcomponent jars inside WEB-INF/lib, but instead all your dependencies should be specified in WEB-INF/jboss-deployment-structure.xml to reference dependencies provided by Application server. Keycloak modules should be added as modules into JBoss AS as specified in documentation.

For example if you look at customer-app application, you can notice that it has all dependencies as 'provided' in pom.xml : https://github.com/keycloak/keycloak/blob/master/examples/demo-template/customer-app/pom.xml#L32 and in jboss-deployment-structure it has dependency on httpcomponents, which is something you will need as well (note ClassNotFoundException in your stacktrace): https://github.com/keycloak/keycloak/blob/master/examples/demo-template/customer-app/src/main/webapp/WEB-INF/jboss-deployment-structure.xml#L6 . Keycloak dependencies (like keycloak-core) don't need to be specified in jboss-deployment-structure.xml as long as you install keycloak modules and add jboss subsystem into standalone.xml as described in Keycloak docs and in README of examples.
