41.	What is Servlet Runner?
	The Servlet Runner is a small utility, intended for testing. It is multi-threaded, and it can run more than one Servlet. It can be used, therefore, to run multiple Servlets simultaneously, or to test one Servlet that calls other Servlets in order to satisfy client request. Unlike some web servers, it does not automatically reload Servlets when they are updated. It assumes that servletrunner is running on the machine, localhost, at port 8080, and that they MyServlet program is located in the Servlet directory provided to Servlet Runner to startup.
