Bill Rosenberg [https://community.jboss.org/people/bill.rosenberg] created the discussion "As 7.2 Log4j Logging" To view the discussion, visit: https://community.jboss.org/message/823536#823536 -------------------------------------------------------------- Logging seemed to work fine when i was using AS 7.1 with log4j libs and code, now when using 7.2, i do not see the expected logging using log4j. I follow the migration guide: *Procedure 3.5. Configure JBoss Enterprise Application Platform 6 to use a log4 j.properties* *or log4 j.xml file* 1. 1. Create a *jboss-deploym ent-structure.xm l* with the following content: <jboss-deploym ent-structure> <deploym ent> <!-- Exclusions allow you to prevent the server from autom atically adding som e dependencies --> <exclusions> <m odule nam e="org.apache.log4j" /> </exclusions> </deploym ent> </jboss-deploym ent-structure> 1. 2. Place the *jboss-deploym ent-structure.xm l* file in either the *MET A-INF/* directory or the *WEB-INF/* directory if you are deploying a WAR, or in the *MET A-INF/* directory if you are deploying an EAR. 1. 3. Include the *log4 j.properties* or *log4 j.xm l* file in the *lib/* directory in your deployment. 2. 4. Start the JBoss Enterprise Application Platform 6 server with the following runtime argument to prevent a *ClassCastException* from appearing in the console when you deploy the application: -Dorg.jboss.as.logging.per-deploym ent=false 1. 5. Deploy your application. And then i get an exception that log4j classes cannot be found, which i would expect if i exclude log4j from the deployment. 12:41:29,192 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-2) MSC000001: Failed to start service jboss.deployment.subunit."LightSpeed.ear"."LightSpeedEJB.jar".INSTALL: org.jboss.msc.service.StartException in service jboss.deployment.subunit."LightSpeed.ear"."LightSpeedEJB.jar".INSTALL: JBAS018733: Failed to process phase INSTALL of subdeployment "LightSpeedEJB.jar" of deployment "LightSpeed.ear"     at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:127) [jboss-as-server-7.2.0.Final-redhat-8.jar:7.2.0.Final-redhat-8]     at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1811) [jboss-msc-1.0.4.GA-redhat-1.jar:1.0.4.GA-redhat-1]     at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1746) [jboss-msc-1.0.4.GA-redhat-1.jar:1.0.4.GA-redhat-1]     at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) [rt.jar:1.7.0_21]     at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) [rt.jar:1.7.0_21]     at java.lang.Thread.run(Thread.java:722) [rt.jar:1.7.0_21] *Caused by: java.lang.NoClassDefFoundError: org/apache/log4j/Priority*     at com.lightspeed.rdp.ejb.RateDynamicStatusBean.<clinit>(RateDynamicStatusBean.java:67)     at java.lang.Class.forName0(Native Method) [rt.jar:1.7.0_21]     at java.lang.Class.forName(Class.java:266) [rt.jar:1.7.0_21]     at org.jboss.invocation.proxy.AbstractProxyFactory.afterClassLoad(AbstractProxyFactory.java:94)     at org.jboss.invocation.proxy.AbstractClassFactory.defineClass(AbstractClassFactory.java:166)     at org.jboss.invocation.proxy.AbstractProxyFactory.getCachedMethods(AbstractProxyFactory.java:145)     at org.jboss.as.ejb3.component.stateless.StatelessComponentDescription$3.configure(StatelessComponentDescription.java:150)     at org.jboss.as.ee.component.ComponentDescription$DefaultComponentConfigurator.configure(ComponentDescription.java:929)     at org.jboss.as.ee.component.deployers.EEModuleConfigurationProcessor.deploy(EEModuleConfigurationProcessor.java:80)     at org.jboss.as.server.deployment.DeploymentUnitPhaseService.start(DeploymentUnitPhaseService.java:120) [jboss-as-server-7.2.0.Final-redhat-8.jar:7.2.0.Final-redhat-8]     ... 5 more Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Priority from [Module "deployment.LightSpeed.ear:main" from Service Module Loader]     at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:196) [jboss-modules.jar:1.2.0.Final-redhat-1]     at org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked(ConcurrentClassLoader.java:444) [jboss-modules.jar:1.2.0.Final-redhat-1]     at org.jboss.modules.ConcurrentClassLoader.performLoadClassChecked(ConcurrentClassLoader.java:432) [jboss-modules.jar:1.2.0.Final-redhat-1]     at org.jboss.modules.ConcurrentClassLoader.performLoadClass(ConcurrentClassLoader.java:374) [jboss-modules.jar:1.2.0.Final-redhat-1]     at org.jboss.modules.ConcurrentClassLoader.loadClass(ConcurrentClassLoader.java:119) [jboss-modules.jar:1.2.0.Final-redhat-1]     ... 15 more -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/823536#823536] Start a new discussion in JBoss AS 7 Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
