[jboss-user] [Installation, Configuration & DEPLOYMENT] - Re: WAR file produces commons-logging LogConfigurationExcept

In case it's interesting, here's what happens when I add the log4j.jar file from JBoss 4.0.1sp1 to the WEB-INF/lib/ directory of the WAR file. That version of log4j.jar is 1.2.8. and I took it from \jboss-4.0.1sp1\server\default\lib\. I am assuming that it is the version of log4j being used when my application runs successfully under JBoss 4.0.1. When I start the 4.2.1. server, these errors are written in the log: 2008-04-09 10:04:31,921 DEBUG [org.jboss.mx.loading.RepositoryClassLoader] setRepository, repository=org.jboss.mx.loading.HeirarchicalLoaderRepository3@5f634c, cl=org.jboss.mx.loading.HeirarchicalLoaderRepository3$CacheClassLoader@6e10d8{ url=null ,addedOrder=0} 2008-04-09 10:04:31,921 ERROR [STDERR] log4j:ERROR A "org.jboss.logging.appender.FileAppender" object is not assignable to a "org.apache.log4j.Appender" variable. 2008-04-09 10:04:31,921 ERROR [STDERR] log4j:ERROR The class "org.apache.log4j.Appender" was loaded by 2008-04-09 10:04:31,921 ERROR [STDERR] log4j:ERROR [org.jboss.mx.loading.UnifiedClassLoader3@19c18ae{ url=file:/C:/jboss-4.2.1.GA/server/default/tmp/deploy/tmp47679nexus-5-0-admin-exp.war/ ,addedOrder=42}] whereas object of type 2008-04-09 10:04:31,921 ERROR [STDERR] log4j:ERROR "org.jboss.logging.appender.FileAppender" was loaded by [org.jboss.system.server.NoAnnotationURLClassLoader@1de3f2d]. 2008-04-09 10:04:31,921 ERROR [STDERR] log4j:ERROR Could not instantiate appender named "FILE".
