Want to learn to build a simple java rest server [

问题:

Hello people of the world!

I'm an Android developer and so far I've worked only on the client side. My next project is in need of a server to communicate with and I wanna try to build it myself.

Can someone give me direction to a good source of learning how to build a nice, small and simple Java restful server?

I've looked around, there is way too much info out there and it's confusing. Maybe one of you was in my shoes already and know a good source for it?

At first you should read and learn how to use Jersey.This is the best implementation of JAX-RS API (REST for Java) https://jersey.java.net/ Then you will need a good HTTP server and Java Servlet container.I advice you to use Jetty http://www.eclipse.org/jetty/ Here good tutorials:

You said "simple server" but if you want high performance then read this tutorial http://www.javarants.com/2008/12/27/using-jax-rs-with-protocol-buffers-for-high-performance-rest-apis/ and use Grizzly container instead of Jetty: https://grizzly.java.net/

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.

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.

Don't forgett to open ports in ur firewall to get the communication to work! to add Internet support in ur Android Manifest!
