Servlets can run in Servlet container only but RESTful services can run in web container as well. RESTful talks about Resources/Entities/Verbs and gives you more Specific way to use the services i.e There is clear explanation on the usage of HTTP verbs.

If the JSP is older than its generated servlet, the JSP container assumes that the JSP hasn't changed and that the generated servlet still matches the JSP's contents. This makes the process more efficient than with the other scripting languages (such as PHP) and therefore faster.

It means an unhandled exception occurred in one of your servlets. You need to check the server logs to get the details of the specific exception that occurred. You have to check your code if correct check server if yes restart.
