Hi! Although I've found very similar questions over the forum, none of them was meeting my requirement.

I am using Tomcat 7 to deploy my spring app. However, I am facing:

‘java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener’ error, java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1714) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1559) at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:532) at org.apache.catalina.core.DefaultInstanceManager.loadClassMaybePrivileged(DefaultInstanceManager.java:514) at org.apache.catalina.core.DefaultInstanceManager.newInstance(DefaultInstanceManager.java:133) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4727) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5285) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:901) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:877) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:618) at org.apache.catalina.startup.HostConfig.deployDirectory(HostConfig.java:1100) at org.apache.catalina.startup.HostConfig$DeployDirectory.run(HostConfig.java:1618) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:722)

I have verified that org.springframework.web-3.1.2.RELEASE.jar is present in the WEB-INF\ \lib\ folder and the required file is present inside it. Kindly note that I am not using any build tool to deploy this web-app like maven.

I have tried to clean and reinstall the app, restarted Tomcat, but didn't have any luck.

Please help.

Check that eclipse (I think you use eclipse because you "cleaned" the server) has really copied the org.springframework.web-3.1.2.RELEASE.jar to the server – Ralph
hi ralph, thankx for your valuable input but right now I am doing a manual copy of my webapp in a separate copy of tomcat running on different folder. – tarunkumar
Can you post a directory listing so we can verify all the files? – sbzoom
Maybe the jar file is corrupted, so download the org.springframework.web-3.1.2.RELEASE.jar again and put it in the WEB-INF folder. (And check that there is no other jar that contains the same class too.) – Ralph

In WEB-INF\ \lib\ where? In artifacts, or in the project? if it is in the project then it does not mean it is in classpath, If you are using eclipse and did not edit output classpath by eclipse - tomcat setting then you should make sure the .jar file is in: ..\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\YourApp\WEB-INF\lib

that is the default place that eclipse makes artifact and deploys it from there. So make sure you included jar file in eclipse build path configuration. First time when you add new jar or something that related to classpath then do: right click on tomcat(in eclipse) then publish from menu, By this way eclipse updates whole artifact.

Worth verifying if you have the project structure and required jars in classpath. You can take help of this if required for set up.

If you are sure all the jars are available in your lib directory, try cleaning tomcat work directory. From eclipse (servers view), right click on Tomcat server and then click on the menu "Clean Tomcat Work Directory).
