Tomcat/Hibernate Problem "SEVERE: Error listenerStart"

I downloaded working example of hibernate (with maven) and installed it on my tomcat, it worked. Then I created a new web project in MyEclipse, added hibernate support and moved all source files (no jar) to this new project and fixed package/paths wherever was necessary. My servlets are responding correctly but when I add "Listener" in web.xml, tomcat returns error "Error ListenerStart" on startup and my application doesn't start.

I've carefully checked all packages, paths and classes, they look good. Error message is also not telling anything more except these two words Here is complete tomcat startup log:

My web.xml is:

</web-app>

Can somebody either help me figure out what I am doing wrong? or point to some resource where I may get some precise solution of my problem?

Sequence of filter and servlet in web.xml was wrong. I moved servlet before filter and the problem is fixed
