I'm trying to deploy an ear to JBoss 4.2. The stack trace shows two error lines below, but there is no prior error as stated. I've seen this before in the past with older versions of Tomcat. The fact that the prior error is not showing is because of a log jar file conflict, or at least that's what is was the last time I encountered it. My ear does not contain a copy of log4j.jar file, so there should be no conflicts, It may be something different this time, but I can't figure it out. I've changed log level in my properties file on everything, so I should see the error even if it's logged at a different level. If anyone has any ideas, please let me know. Thanks... 14:28:34,089 INFO [EARDeployer] Init J2EE application: file:/C:/AppServers/jboss-4.2.0.GA/server/SASServer1/deploy_sas/sas.solutions.fairbanking.ear 14:29:20,311 ERROR [StandardContext] Error listenerStart 14:29:20,311 ERROR [StandardContext] Context [/SASFairBanking] startup failed due to previous errors 14:29:22,294 WARN [ServiceController] Problem starting service jboss.web.deployment:war=sas.solutions.fairbanking.war,id=725441180 org.jboss.deployment.DeploymentException: URL file:/C:/AppServers/jboss-4.2.0.GA/server/SASServer1/tmp/deploy/tmp11282sas.solutions.fairbanking.ear-contents/sas.solutions.fairbanking-exp.war/ deployment failed at org.jboss.web.tomcat.service.TomcatDeployer.performDeployInternal(TomcatDeployer.java:379) at org.jboss.web.tomcat.service.TomcatDeployer.performDeploy(TomcatDeployer.java:104) at org.jboss.web.AbstractWebDeployer.start(AbstractWebDeployer.java:375) at org.jboss.web.WebModule.startModule(WebModule.java:83) at org.jboss.web.WebModule.startService(WebModule.java:61) at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:289) at org.jboss.system.ServiceMBeanSupport.jbossInternalLifecycle(ServiceMBeanSupport.java:245) at sun.reflect.GeneratedMethodAccessor4.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) at org.jboss.mx.server.Invocation.invoke(Invocation.java:86) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) at org.jboss.system.ServiceController$ServiceProxy.invoke(ServiceController.java:978) at $Proxy0.start(Unknown Source) at org.jboss.system.ServiceController.start(ServiceController.java:417) at sun.reflect.GeneratedMethodAccessor10.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) at org.jboss.mx.server.Invocation.invoke(Invocation.java:86) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) at org.jboss.mx.util.MBeanProxyExt.invoke(MBeanProxyExt.java:210) at $Proxy46.start(Unknown Source) at org.jboss.web.AbstractWebContainer.start(AbstractWebContainer.java:466) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4170850#...
