ZK - Open Source Ajax Java Framework

Hello guys,
I have created a ZK Project with Eclipse, and when i start tomcat in the console tab i got this error:

java.lang.ClassNotFoundException: org.zkoss.zk.ui.http.HttpSessionListener

What's the problem?
Thanks in advice.

Hi dkyhax
What version of ZK do you use?
Could you provide your zk.xml?

Hello,

I'm having the same problem.

I've just installed eclipse EE, tomcat 6.0.35 and i'm running the "Todo" example.
I'm using ZK Studio 1.0.1

Hi jesusem,
I have tried download todo.war and import the war file into my eclipse,
it works fine.
