Failed to load module for org.postgresql

[zafinxueqian]

I created module.xml in
/opt/jboss/wildfly/modules/org/postgres/main and downloaded postgresql-9.4.1212.jar in the same folder.
Then I used my customer configuration file. I added datasource and postgres driver in it. But finally I got error:

ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 33) WFLYCTL0013: Operation ("add") failed - address: ([
("subsystem" => "datasources"),
("jdbc-driver" => "postgresql")
]) - failure description: "WFLYJCA0041: Failed to load module for driver [org.postgresql]"

I think is a bug for adding postgresql driver, thanks

@zafinxueqian - did you ever get this resolved? I'm facing the same issue, and this seems to work fine for natively installed wildfly

I have the same issue. This is driving me nuts.

This worked in my case:

FROM jboss/wildfly

ENV JBOSS_HOME /opt/jboss/wildfly

#add some deployment
ADD some.war /opt/jboss/wildfly/standalone/deployments/

# add special standalone configuration with postgres datasource
ADD standalone-special.xml /opt/jboss/wildfly/standalone/configuration/

# use root user to download a copy of the postgres driver into a new modules directory
USER root

# download postgres driver
RUN set -x && mkdir -p /opt/jboss/wildfly/modules/system/layers/base/org/postgresql/main
RUN curl -L https://jdbc.postgresql.org/download/postgresql-42.2.2.jar -o /opt/jboss/wildfly/modules/system/layers/base/org/postgresql/main/postgresql-42.2.2.jar

# add postgres module
ADD module.xml /opt/jboss/wildfly/modules/system/layers/base/org/postgresql/main/

#use jboss user to start wildfly
USER jboss

# Start WildFly using the standalone mode
CMD ["/opt/jboss/wildfly/bin/standalone.sh", "-c", "standalone-special.xml", "-b", "0.0.0.0", "-bmanagement", "0.0.0.0"]

have a look at your permissions on folder /opt/jboss/wildfly/modules/system/layers/base/org/postgresql/. they should be the same as all other module permissions

check the postgres driver jar file is not corrupted and a can be read by the java process
