[keycloak-user] [HELP] Unable to configure postgreSQL datasource

[tostasul at cock.li]

Hello,

I'm trying to configure a PostgresSQL datasource by following the 
tutorial presented in the documentation: 
https://keycloak.gitbooks.io/documentation/server_installation/topics/database.html 
.
I'm doing the configuration for a standalone server by running 
standalone.bat and by configuring everything in 
keycloak-3.0.0.Final/standalone/configuration/standalone.xml .

I'm following the documentation step-by-step, but I get the following 
error running standalone.bat every-time, and thus I'm unable to connect 
to the database.

     "org.wildfly.data-source.KeycloakDS is missing

I have tried different versions of JDBC drivers provided by: 
https://jdbc.postgresql.org/download.html, but to no avail, even by 
using the version mentioned in the documentation.

At this point I am stuck since my configuration files look exactly like 
in the documentation. What exactly could I be missing? Is the 
documentation up to date?

Thanks in advance for any help,

My best regards.
