[keycloak-user] Exception loading Keycloak modules in Wildfly 9.0

Checking the documentation for our examples I realise it needs a lot of
improvement, and it's especially out of date for the demo :/
So here are the full command line instructions that work for me. If you're
on windows you'll have to translate some of these commands into CLI /
PowerShell.
Since you are only trying to install adapter I assume you want to run
Keycloak server separately from your content server, but the demo works
out-of-the box only when server and protected content are deployed in the
same Wildfly instance. The instructions here configure server part
separately from the client part, but within the same Wildfly instance.
So here we go ...
Download Wildfly 9.0.1, Keycloak Server, Keycloak Wildfly 9 Adapter, and
Keycloak Examples. Use Google to find the Download pages ...
mkdir keycloak
cd keycloak
unzip ~/Downloads/wildfly-9.0.1.Final.zip
cd wildfly-9.0.1.Final
unzip ~/Downloads/keycloak-overlay-1.6.0.Final.zip
unzip ~/Downloads/keycloak-wf9-adapter-dist-1.6.0.Final.zip
(press 'A' for All when ask if you want to overwrite existing files -
adapter and server overlay contain some of the same modules, since each has
to be fully functional by itself)
Now we should open and edit standalone/configuration/standalone.xml to
configure the server (and adapter) part, but we can also configure it
directly through shell using jboss-cli tool:
bin/jboss-cli.sh
embed-server
/subsystem=datasources/data-source=KeycloakDS/:add(connection-url="jdbc:h2:${jboss.server.data.dir}/keycloak;AUTO_SERVER=TRUE",driver-name=h2,jndi-name=java:jboss/datasources/KeycloakDS,password=sa,user-name=sa,use-java-context=true)
/subsystem=infinispan/cache-container=keycloak:add(jndi-name="infinispan/Keycloak")
/subsystem=infinispan/cache-container=keycloak/local-cache=realms:add()
/subsystem=infinispan/cache-container=keycloak/local-cache=users:add()
/subsystem=infinispan/cache-container=keycloak/local-cache=sessions:add()
/subsystem=infinispan/cache-container=keycloak/local-cache=loginFailures:add()
/extension=org.keycloak.keycloak-server-subsystem/:add(module=org.keycloak.keycloak-server-subsystem)
/subsystem=keycloak-server:add(web-context=auth)
quit
The configuration changes will be saved to standalone.xml file.
We can do the same in order to configure the adapter part:
bin/jboss-cli.sh
embed-server
/extension=org.keycloak.keycloak-adapter-subsystem/:add(module=org.keycloak.keycloak-adapter-subsystem)
/subsystem=keycloak:add()
quit
Again the changes will be saved to standalone.xml file.
Keycloak is now ready to run, but let's build, and deploy the demo, so that
when we run Wildfly everything will be set up already.
Unpack, and build the demo:
cd ..
unzip ~/Downloads/keycloak-examples-1.6.0.Final.zip
cd keycloak-examples-1.6.0.Final/
cd preconfigured-demo/
mvn clean install
Deploy by copying to deployments dir:
cp database-service/target/database.war
../../wildfly-9.0.1.Final/standalone/deployments/
cp customer-app/target/customer-portal.war
../../wildfly-9.0.1.Final/standalone/deployments/
cp product-app/target/product-portal.war
../../wildfly-9.0.1.Final/standalone/deployments/
We also need to load into Keycloak server the demo realm that contains
roles, users, and application clients for our demo to work. We can do this
while starting up Keycloak server.
cd ../..
cd wildfly-9.0.1.Final
bin/standalone.sh -Dkeycloak.migration.action=import
-Dkeycloak.migration.provider=singleFile
-Dkeycloak.migration.realmName=demo
-Dkeycloak.migration.file=../keycloak-examples-1.6.0.Final/preconfigured-demo/testrealm.json
Next time you start up Wildfly only use:
bin/standalone.sh
Otherwise you'll get an exception during startup notifying you that the
'demo' realm can't be imported, as it already exists!
Your Wildfly running Keycloak server, and the content apps (our demo,
composed of customer-portal.war, product-portal.war, and database.war) is
now ready for use. You can go to:
http://localhost:8080/customer-portal
and click around. When prompted for login, use 'bburke at redhat.com' as a
username, and 'password' as a password.
Let me know if these instructions still don't work for you.
