The default installation of Tomcat sets the maximum number of HTTP servicing threads at 200. Effectively, this means that the system can handle a maximum of 200 simultaneous HTTP requests.
This error indicates that the server could not find the desired resource. This resource can be any file such as JSP, HTML, or image resource. Usually, the resource is present, but it is referenced incorrectly. In most cases, you can fix this by correcting the URL.
You are getting 404 error because of the action="/ReceiveMessagesServlet", please remove the slash. Try with action="ReceiveMessagesServlet".
When you add a slash to URL pattern then the container will look for a web application deployed with name 'ReceiveMessagesServlet'.Since this not there you will receive 404 error.
