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

Friday, 23 October 2015

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improvement, and it's especially out of date for the demo :/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 &#39;bburke(a)redhat.com&#39; 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*

<http://keycloak.jboss.org/keycloak/downloads.html?dir=0%3Dadapters/keyclo...

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 different kind of config, and is outdated.
