Tomcat webapp deployment failing

Error log when starting tomcat. I have wookie webapp in tomcat/webapps directory.

org.apache.catalina.startup.HostConfig deployDirectory
INFO: Deploying web application directory wookie
org.apache.catalina.core.StandardContext startInternal
SEVERE: Error listenerStart

These are the three lines related to listener in web.xml

<listener>
            <listener-class>
                    org.apache.wookie.server.ContextListener
            </listener-class>
    </listener>

    <listener>
            <listener-class>
                    org.directwebremoting.servlet.EfficientShutdownServletContextAttributeListener
            </listener-class>
    </listener>

    <listener>
            <listener-class>
                    org.directwebremoting.servlet.EfficientShutdownServletContextListener
            </listener-class>
    </listener>

Does it make sense to anyone of you?

I have more information

Update::: SOLUTION
The above error was caused in my PC due to incorrect servletEngine.context.conf.dir path.
servletEngine.context.conf.dir=CATALINA_HOME/conf (incorrect)
servletEngine.context.conf.dir=CATALINA_HOME/conf/Catalina/localhost (correct)
/Catalina/localhost after conf is necessary
