I get message Error configuring application listener of class org.springframework.web.context.ContextLoaderListener while deploying a Spring application in tomcat

What can be the issue
thanks

Generally, "ClassNotFOundException" means that the class was not found. THis could either be because you made a mistake in specifying the class/package name, or the class is not in classpath

Which jar am I missing?

[Jayesh A Lalwani]

It should be in spring-web.. Have you checked if your ear/war is being packaged correctly? Is it inside your ear/war?

[Monica Shiralkar]

I have spring-web-3.0.6.RELEASE.jar in the classpath but it still shows the same error message. I tried running it from the Eclipse and also by creating the war and putting in tomcat deploy director but both ways got the same message.

[Prasad Krishnegowda]

You are having 3 different version of spring-web jar file, i would suggest to remove the spring-web.jar and spring-web-3.0.6.jar and stick to spring 3.1.1 version alone.
