顯示java.lang.NullPointerException org.red5.logging.LoggerContextFilter.doFilter（LoggerContextFilter

Question

我碰到下面的錯誤RED5當我使用，LoggerContextFilter

任何想法，我可能會使用RED5版本1.0.7做錯了，

過濾器：

<filter> 
     <filter-name>LoggerContextFilter</filter-name> 
     <filter-class>org.red5.logging.LoggerContextFilter</filter-class> 
    </filter> 

    <filter-mapping> 
     <filter-name>LoggerContextFilter</filter-name> 
     <url-pattern>/*</url-pattern> 
    </filter-mapping> 

錯誤：

**java.lang.NullPointerException 
    org.red5.logging.LoggerContextFilter.doFilter(LoggerContextFilter.java:63)**

我所有的W的ebapps在web.xml中有這個

<listener> 
    <listener-class>org.red5.logging.ContextLoggingListener</listener-class> 
</listener> 

<filter> 
    <filter-name>LoggerContextFilter</filter-name> 
    <filter-class>org.red5.logging.LoggerContextFilter</filter-class> 
</filter> 

<filter-mapping> 
    <filter-name>LoggerContextFilter</filter-name> 
    <url-pattern>/*</url-pattern> 
</filter-mapping> 

我想你只是想念聽衆。
