JBoss-5.1.0.GA Multiple SLF4J bindings

jboss5本身有引用slf4j包，如果项目也有引用此包，就会报：

15:28:09,222 ERROR [STDERR] SLF4J: Class path contains multiple SLF4J bindings.
15:28:09,222 ERROR [STDERR] SLF4J: Found binding in [vfszip:/home/ihrytsyuk/work/ml/jboss/common/lib/slf4j-jboss-logging.jar/org/slf4j/impl/StaticLoggerBinder.class]
15:28:09,222 ERROR [STDERR] SLF4J: Found binding in [vfszip:/home/ihrytsyuk/work/ml-dev/out/exploded/eee.ear/lib/slf4j-log4j12-1.6.1.jar/org/slf4j/impl/StaticLoggerBinder.class] 
15:28:09,222 ERROR [STDERR] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

解决办法：
修改JBOSS_HOME/server/< servername>/deployers/jbossweb.deployer/META-INF/war-deployers-jboss-beans.xml，添加org.slf4j，以过滤该包：

<!-- Allow for war local class loaders: in testing -->
   <bean name="WarClassLoaderDeployer" class="org.jboss.web.tomcat.service.deployers.WarClassLoaderDeployer">
      <property name="relativeOrder">-1</property>
      <property name="filteredPackages">javax.servlet,org.apache.commons.logging,org.slf4j</property>      
   </bean>
