Answer 1

You can solve this problem after restarting the server, the server iscaching older version of the app.

see here

Answer 2

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.

Answer 3

I have also experienced this problem recently. In my case the problem was generated by an unhandled exception in javax.servlet.ServletContextListener which was logged in one localhost-date.log. Because of that exception the webapp was not deployed, but an already started java.util.concurrent.Executors was still running which caused another chain of exceptions in catalina-date.log:
java.lang.IllegalStateException: Illegal access: this web application instance has been stopped already. Could not load WhatEver.class .

The solution for my case:

• check all the Tomcat logs
• fix exceptions in javax.servlet.ServletContextListener

Answer 4

For me this error occurred due to wrong java version. I installed the required java version and error got resolved.

Answer 5

I have faced the similar issue. I have solved by increasing the permsize of Server in the VM arguments -XX:MaxPermSize=1024m

Answer 6

I have faced a similar issue. For me this error occurred due to calling of an init method of an ApplicationScoped bean from a SessionScoped bean.
