A multi-threaded (e.g. file-based) web server with thread-pooling implemented in Java.

Any class that implements WebApp interface can be plugged as the handler application. In this example I'm using FileServingApp (serves static files from a document root) as my handler application. The single method that must be implemented is HttpResponse handle(HttpRequest request).

1. Server receives a request.
2. Server creates a Handler (Runnable) for this request.
3. Handler parses the request into a HttpRequest.
4. Handler passes the HttpRequest to the handler application.
5. Handler writes the response received from the handler application to the output stream.
6. Handler closes the streams.

A compiled version webserver-1.0-SNAPSHOT.jar can be found in the root directory.

WebServer - listens for connections and delegates them to worker threads.

Handler - handles a single request, by parsing it and sending it to the handler application.

ExecutorMonitor - prints server status once every 10 seconds.

FileServingApp - an application that serves static files from it's document root.
