Beginner question, but I'm a bit stuck. I've followed ZK's instructions for loading and using ZK Studio within Eclipse (both current versions as of 1/18/2014). And I'm using tomcat 7 as a server in Eclipse. I create a new ZK project (File->New->Other->ZK Project) and try to Run on Server. I always get this error in the server console:

SEVERE: Error configuring application listener of class org.zkoss.zk.ui.http.HttpSessionListener java.lang.ClassNotFoundException: org.zkoss.zk.ui.http.HttpSessionListener

I can see that the class is defined in zk.jar, which is attached to the project, along with a number of other ZK jars. Following advice in related posts I've removed all other ZK jars, but the problem persists.

What am I missing?

When you do build your project. Does that file contains the zk.jar? Is the classpath correct? Otherwise you can put the zk jars under' tomcat classpath. Greetz chill

Chillworld -- thanks for your response. I've concluded that I'm trying to do too many things at once. The jar files clearly show up in the "Java Build Path" in Eclipse -- as expected from a ZK-Eclipse integration. But still no luck. Will revert to a manual build to figure it out.
