Dear all, first of all - thanks for your effort for Keycloak – great product! I’m trying to do a POC for the authorization API in Keycloak and therefore I downloaded from the project’s website the Demo distribution and tried to follow the readme instructions on the “photoz” example. The import of the realm was successful, but when I tried to load the resource server configuration JSON I received the following exception in the log file: Caused by: java.lang.ClassNotFoundException: org.apache.commons.codec.binary.Base64 from [Module "org.drools:main" from local module loader @1476ceae (finder: local module finder @1b4febf3 ( roots: D:\dev\software\keycloak\keycloak-demo-2.1.0.Final\keycloak\modules, D:\dev\software\keycloak\keycloak-demo-2.1.0.Final\ keycloak\modules\system\layers\keycloak, D:\dev\software\keycloak\keycloak-demo-2.1.0.Final\ keycloak\modules\system\layers\base ))] I was able to fix this issue by providing the following dependency entry in the drools module description for the commons-codec module at <KEYCLOAK_ROOT>\keycloak\modules\system\add-ons\keycloak\org\drools\main\ module.xml After this I could successfully import the “photoz-restful-api-authz-service.json” finally. Could it be that this entry is also missing in the source code at *https://github.com/keycloak/keycloak/tree/master/distribution/feature-packs/server-feature-pack/src/main/resources/modules/system/layers/keycloak/org/drools/main/* *module.xml* <https://github.com/keycloak/keycloak/tree/master/distribution/feature-pac... ? <dependencies> <module name="javax.api"/> <module name="javax.inject.api"/> <module name="javax.enterprise.api"/> <module name="org.slf4j"/> *<module name="org.apache.commons.codec"/>*<!-- this one is missing --> <module name="org.apache.commons.logging"/> <module name="org.keycloak.keycloak-core"/> <module name="org.keycloak.keycloak-common"/> <module name="org.keycloak.keycloak-server-spi"/> </dependencies> I also found a related JIRA “*KEYCLOAK-3279* <https://issues.jboss.org/browse/KEYCLOAK-3279> Possible error with Drools policies when running on Windows” entry but this was closed without code fix, I think. Can you verify this finding?
