Hello,

I am using zk calender in my application and I have updated all zk libs from version 5.0 to 7.0.3.I am using Eclipse IDE and Tomcat for development.I have cleared all work folders & files from Tomcat before building the application but I am facing following exception at some listeners while starting my tomcat server.

SEVERE: Error configuring application listener of class org.zkoss.zk.ui.http.HttpSessionListener java.lang.ClassNotFoundException: org.zkoss.zk.ui.http.HttpSessionListener at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1701) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1546) at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:525) at org.apache.catalina.core.DefaultInstanceManager.loadClassMaybePrivileged(DefaultInstanceManager.java:507) at org.apache.catalina.core.DefaultInstanceManager.newInstance(DefaultInstanceManager.java:124) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4715) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5273) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:895) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:871) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:615) at org.apache.catalina.startup.HostConfig.deployDescriptor(HostConfig.java:649) at org.apache.catalina.startup.HostConfig$DeployDescriptor.run(HostConfig.java:1581) at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

I guess there are some classes which are missing.Could somebody please help me out as it is blocking my application to start.

Thanks in advance.
