Checking the documentation for our examples I realise it needs a lot of improvement, and it's especially out of date for the demo :/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@redhat.com' as a username, and 'password' as a password.

Let me know if these instructions still don't work for you.

Thanks, Marco. I was able to move forward by using the latest adapter you pointed me to. I was able to bring up the Wildfly 9.0 server with the adapter installed and was able to install the Customer-Portal and Product-Portal example apps successfully. But, when I install the Database example app, I get the following error. Any tips on how to resolve this error ? Thanks.

Use the latest keycloak-wf9-adapter-dist from the download site: http://keycloak.jboss.org/keycloak/downloads.html?dir=0%3Dadapters/keycloak-oidc%3B

You're trying to use latest config syntax with an old version that uses a different kind of config, and is outdated.
