A while back, I ranted about the Simple Frameworkexample code and its unnecessary complexity. It turns out that their HTTP server library is indeed simple, if you just ignore the Spring setup and their example. In fact, as this static file server example shows, it’s very similar to the “hidden” Sun HTTP handler API.
The only interface which has to be implemented is the Container, which is equivalent to the request HttpHandler in the Sun HTTP library. The handle() method takes a normal HTTP request, and the response code and data can be written via the Response object. The first code block below shows a simple handler.
The next block shows how to tie the required Simple Framework classes together to start the server. The Container just mentioned goes into a ContainerSocketProcessor where concurrent processing can be setup up. The processor goes into a SocketConnection which connects to a socket on a given host and port, and the server runs.
Here is the full server example, started and verified as a unit test.
