5 years ago The message indicates that you are missing the spring-web-xxx.jar library. Is it present in the UniTime.war, WEB-INF/lib folder)?
I sometimes get this (or similar) error when I am running tomcat and deploying UniTime within eclipse (see here). What seems to work for me is to
- un-deploy UniTime and restart the tomcat (on the Servers tab, remove the UniTime web module; also make sure that webapps/UniTime is deleted)
- stop the tomcat, deploy UniTime again, and start the tomcat
Everything is usually back to normal after this.
The UniTime application source code was working fine in my local. Since 2 days I am getting this error without any code change : SEVERE: Error configuring application listener of class org.springframework.web.context.ContextLoaderListener java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1955) at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1798) at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:536) at org.apache.catalina.core.DefaultInstanceManager.loadClassMaybePrivileged(DefaultInstanceManager.java:518) at org.apache.catalina.core.DefaultInstanceManager.newInstance(DefaultInstanceManager.java:148) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:5113) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5720) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:145) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:1018) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:994) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:652) at org.apache.catalina.startup.HostConfig.deployWAR(HostConfig.java:1127) at org.apache.catalina.startup.HostConfig$DeployWar.run(HostConfig.java:2020) at java.util.concurrent.Executors$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)
