JBOSS LOG4J冲突的解决办法

1.删除掉工程下WEBAPP目录LIB中的log4j包

2.修改JBOSS_HOME/server/default/deploy/jbossweb-tomcat55.sar/META-INF/jboss-service.xml

<attribute name="Java2ClassLoadingCompliance">false</attribute>

<attribute name="UseJBossWebLoader">false</attribute>

 

3.修改JBOSS_HOME/server/default/conf/jboss-service.xml

<!-- ==================================================================== -->
   <!-- Log4j Initialization                                                 -->
   <!-- ==================================================================== -->

   <mbean code="org.jboss.logging.Log4jService"
      name="jboss.system:type=Log4jService,service=Logging"
      xmbean-dd="resource:xmdesc/Log4jService-xmbean.xml">
      <attribute name="ConfigurationURL">resource:log4j.xml</attribute>
      <!-- Set the org.apache.log4j.helpers.LogLog.setQuiteMode. As of log4j1.2.8
      this needs to be set to avoid a possible deadlock on exception at the
      appender level. See bug#696819.
