Hi, I am using Jboss 4.2.2GA I am fine when I have log4j.properties file. But I want to switch to jboss-log4j.xml. I wanted to go with this because, this file can be hot deployed. When trying to do this, I am getting the following error 16:50:32,765 ERROR [STDERR] log4j:ERROR A "org.jboss.logging.appender.FileAppender" object is not assignable to a "org.apache.log4j.Appender" variable. 16:50:32,765 ERROR [STDERR] log4j:ERROR The class "org.apache.log4j.Appender" was loaded by 16:50:32,765 ERROR [STDERR] log4j:ERROR [WebappClassLoader delegate: false repositories: /WEB-INF/classes/ ----------> Parent Classloader: java.net.FactoryURLClassLoader@1891732 ] whereas object of type 16:50:32,765 ERROR [STDERR] log4j:ERROR "org.jboss.logging.appender.FileAppender" was loaded by [org.jboss.system.server.NoAnnotationURLClassLoader@10f6d3]. 16:50:32,765 ERROR [STDERR] log4j:ERROR Could not instantiate appender named "FILE". My jboss-log4j.xml is <!-- Rollover at midnight each day --> <!-- Rollover at the top of each hour <param name="DatePattern" value="'.'yyyy-MM-dd-HH"/> --> <!-- The default pattern: Date Priority [Category] Message\n --> <!-- The full pattern: Date MS Priority [Category] (Thread:NDC) Message\n --> Is there any thing wrong with my file?
