Hi,

It's ok to remove KeycloakDS datasource from standalone.xml if you switch to mongo model, but note that in this case, you should also remove file standalone/deployments/auth-server.war/WEB-INF/classes/META-INF/persistence.xml .

If you remove just datasource, but keep persistence.xml, then Application server will automatically try to initialize JPA from persistence.xml file, but in this case it won't work as persistence.xml contains reference to KeycloakDS datasource, which is not available.

You need to either:
- Remove both KeycloakDS and persistence.xml file (that's recommended to have a bit faster startup time)
- Keep both datasource and persistence.xml

Hope it helps,
Marek

Hi everybody,
I'm tryng to use keycloak withh mongo.

I followed the documantation:
http://docs.jboss.org/keycloak/docs/1.0-alpha-3/userguide/html/server-installation.html#d4e167

But removing datasource KeycloakDS from standalone/configuration/standalone.xml causes an error message:

13:10:56,838 INFO  [org.jboss.as.jpa] (MSC service thread 1-1) JBAS011401: Read persistence.xml for jpa-keycloak-identity-store

Suggestions?

Thanks
