Question

I had like to implement my own web-server in pure Java
the web-server should support only static resources (i.e. html, js, css, pics, movies etc..)

Can you recommend a tutorial or an article on how to implement such a thing?
should I use few processes or a thread-pool or should I consider a loop-event oriented like NodeJS?

I know there are free web-servers that does exactly what I am looking for, but I had like to do it as an exersice to my self.

I recommend familiarizing yourself with the HTTP request format http://datatracker.ietf.org/doc/rfc2616/. Implementing HTTP from scratch is no small feat, but it is certainly a good learning exercise.

Within Java itself for simplicity I recommend using a thread-per-request server – http://tutorials.jenkov.com/java-multithreaded-servers/multithreaded-server.html – that using java.nio for serving files. In a concurrent setting java.nio is preferable to java.io because it balances load better. You will likely find benchmarks that suggest that java.io is faster, but that is for sequential single-threaded code.
