Cannot set web app root system property when WAR file is not expanded

 Cannot set web app root system property when WAR file is not expanded

在tomcat下面可以，在weblogic下面不行的處理方法；

學習了http://blog.csdn.net/ouvidia/article/details/38453353

我采用了在web.xml 中配置 如下參數的方法：

    <!-- Cannot set web app root system property when WAR file is not expanded 異常處理 -->
    <context-param>  
      <param-name>log4jExposeWebAppRoot</param-name>  
      <param-value>false</param-value>  
    </context-param>
