Exception sending context initialized event to listener

[vikka sharma]

When i am running my application it give me this exception:-

Exception sending context initialized event to listener instance of class org.springframework.web.util.Log4jConfigListener
java.lang.ExceptionInInitializerError



But this problem is not permanent. Id i remove the log4j entries from web.xml and restart p.c and then again add log4j entries and start the server, then the application works fine.
I noticed that when the application is deployed and when i undeploy and again deploy the same application, this problem emerge.

Please help me ........ i am facing this problem from 3 months...

It cause when multiple jar file for log4j is available to application.
From web/application server and from build path(Included from other path rather than web/application server)
