Want to learn to build a simple java rest server [closed]

Answer 1

First of all you should read up on and learn how to use Jersey. This is the best implementation of JAX-RS API (REST for Java).

You will also need a good HTTP server and Java Servlet container. For that I'd advise you to use Jetty. Here are a few good tutorials:

1. Crunchify: Build RESTful Service in Java using JAX-RS and Jersey (Celsius to Fahrenheit & Fahrenheit to Celsius)
2. Vogella: REST with Java (JAX-RS) using Jersey - Tutorial

You asked for a "simple server", however if you're looking for high performance then read this tutorial: Javarants: Using JAX-RS with Protocol Buffers for high-performance REST APIs, and use the Grizzly container instead of Jetty:

Answer 2

If you intend to build a simple server with sockets, you could try:

• this SO thread for starters.
• this interesting tutorial about sockets, and
• the official Oracle page about sockets.

Edit this doesn't cover the "restful" side of your question though.

Answer 3

I just went trough this myself creating a Java server with Android client. And this two links provided plenty of info! a tip is to search for Java Socket server.

to learn JavaSocket I use http://docs.oracle.com/javase/tutorial/networking/sockets/clientServer.html And to pull it all togheter with Android client and ServerSide.
