解决log4j.xml问题http//jakarta.apache.org/log4j/ uri is not register

    在Eclipse中，配置log4j.xml出现“http //jakarta.apache.org/log4j/ uri is not registered”的错误信息。

原始的log4j.xml配置文件：

1. 
   
   <?xml version="1.0" encoding="GB2312" ?>
2. 
   
   <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
3. 
   
   
   
4. 
   
   <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="true">

     解决方法，具体修改如下所示。

<?xml version="1.0" encoding="GB2312" ?>
<!DOCTYPE log4j:configuration SYSTEM "http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/xml/doc-files/log4j.dtd">

<log4j:configuration debug="true">
