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. 15:39:28,922 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-5) MSC000001: Failed to start service jboss.deployment.unit.database.POST_MODULE: org.jboss.msc.service.StartE xception in service jboss.deployment.unit.database.POST_MODULE: WFLYSRV0153: Failed to pro cess phase POST_MODULE of deployment "database" at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitP haseService.java:163) at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceContr ollerImpl.java:1948) at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl .java:1881) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: WFLYRS0006: C ould not load JAX-RS Application class at org.jboss.as.jaxrs.deployment.JaxrsScanningProcessor.scan(JaxrsScanningProcesso r.java:205) at org.jboss.as.jaxrs.deployment.JaxrsScanningProcessor.deploy(JaxrsScanningProces sor.java:101) at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitP haseService.java:156) ... 5 more Caused by: java.lang.ClassNotFoundException: org.keycloak.example.oauth.DataApplication fr om [Module "deployment.database:main" from Service Module Loader] at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:205) at org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked(ConcurrentCla ssLoader.java:455) at org.jboss.modules.ConcurrentClassLoader.performLoadClassChecked(ConcurrentClass Loader.java:404) at org.jboss.modules.ConcurrentClassLoader.performLoadClass(ConcurrentClassLoader. java:385) at org.jboss.modules.ConcurrentClassLoader.loadClass(ConcurrentClassLoader.java:13 0) at org.jboss.as.jaxrs.deployment.JaxrsScanningProcessor.scan(JaxrsScanningProcesso r.java:201) ... 7 more 15:39:28,937 ERROR [org.jboss.as.controller.management-operation] (management-handler-thre ad - 5) WFLYCTL0013: Operation ("add") failed - address: ({"deployment" => "database"}) - failure description: {"WFLYCTL0080: Failed services" => {"jboss.deployment.unit.database.P OST_MODULE" => "org.jboss.msc.service.StartException in service jboss.deployment.unit.data base.POST_MODULE: WFLYSRV0153: Failed to process phase POST_MODULE of deployment \"databas e\" Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: WFLYRS000 6: Could not load JAX-RS Application class Caused by: java.lang.ClassNotFoundException: org.keycloak.example.oauth.DataApplicatio n from [Module \"deployment.database:main\" from Service Module Loader]"}} 15:39:28,953 ERROR [org.jboss.as.server] (management-handler-thread - 5) WFLYSRV0021: Depl oy of deployment "database" was rolled back with the following failure message: {"WFLYCTL0080: Failed services" => {"jboss.deployment.unit.database.POST_MODULE" => "org.j boss.msc.service.StartException in service jboss.deployment.unit.database.POST_MODULE: WFL YSRV0153: Failed to process phase POST_MODULE of deployment \"database\" Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: WFLYRS000 6: Could not load JAX-RS Application class Caused by: java.lang.ClassNotFoundException: org.keycloak.example.oauth.DataApplicatio n from [Module \"deployment.database:main\" from Service Module Loader]"}} 15:39:28,953 INFO [org.jboss.as.server.deployment] (MSC service thread 1-1) WFLYSRV0028: Stopped deployment database (runtime-name: database) in 11ms 15:39:28,953 INFO [org.jboss.as.controller] (management-handler-thread - 5) WFLYCTL0183: Service status report WFLYCTL0186: Services which failed to start: service jboss.deployment.unit.database .POST_MODULE Regards, Vijay From: Marko Strukelj <mstrukel(a)redhat.com&gt; To: Vijay Bhadriraju/Raleigh/IBM@IBMUS Cc: keycloak-user <keycloak-user(a)lists.jboss.org&gt; Date: 10/22/2015 12:47 PM Subject: Re: [keycloak-user] Exception loading Keycloak modules in Wildfly 9.0 Use the latest keycloak-wf9-adapter-dist from the download site: http://keycloak.jboss.org/keycloak/downloads.html?dir=0%3Dadapters/keyclo...
