All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class Log4jConfigurationServlet
extends javax.servlet.http.HttpServlet

A servlet used to dynamically adjust package logging levels while an application is running. NOTE: This servlet is only aware of pre-configured packages and packages that contain objects that have logged at least one message since application startup.

web.xml configuration:

 <servlet>
   <servlet-name>log4j</servlet-name>
   <display-name>Log4j configuration Servlet</display-name>
   <servlet-class>it.openutils.log4j.Log4jConfigurationServlet</servlet-class>
 </servlet>
 

The fragment parameter can be added if you don't want a full xhtml page in output, but only the content of the body tag, so that it can be used in portlets or struts tiles.

 <servlet>
   <servlet-name>log4j</servlet-name>
   <display-name>Log4j configuration Servlet</display-name>
   <servlet-class>it.openutils.log4j.Log4jConfigurationServlet</servlet-class>
   <init-param>
     <param-name>fragment</param-name>
     <param-value>true</param-value>
   </init-param>
 </servlet>
