将我的war文件部署到tomcat时出现错误：

log4j:WARN The content of element type "log4j:configuration" must match "(renderer*,throwableRenderer?,appender*,plugin*,(category|logger)*,root?,(categoryFactory|loggerFactory)?)"

我四处搜寻，发现log4j.xml的顺序可能是错误的，但应该是正确的。

<?xml version="1.0" encoding="UTF-8" ?>  
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

  <appender name="console" class="org.apache.log4j.ConsoleAppender">  
    <param name="Target" value="System.out"/>  
    <layout class="org.apache.log4j.PatternLayout">  
      <param name="ConversionPattern" value="%-5p %d %c %x - %m%n"/>  
    </layout>  
  </appender>

  <root>  
    <priority value ="error" />  
    <appender-ref ref="console" />  
  </root>

  <category name="org.springframework" additivity="false">  
    <priority value="info" />  
    <appender-ref ref="console" />  
  </category>

</log4j:configuration>

有什么建议么？
