You can solve this problem after restarting the server, the server iscaching older version of the app.
see here
You cannot resolve this problem by "restarting the server".
The problem is that when you update your app by uploading a new version to Tomcat, some resource is not cleaned up properly. Could be anything from a runaway thread, to some kind of scheduled service, to a listener. When that process tries to load a class, Tomcat will detect and prevent it.
The solution to the problem is to properly keep track of, and on shutdown close, those threads.
