A beginners guide to Server programming with java

First of all, I'm not new to java but I'm new to JavaWEB and Java server. So.. I'm creating a game that will manipulate data from an existing database.

The problem i开发者_运维问答s: I don't know where to start from since I know nothing about these things.

I want to create a server side that will manipulate data for more than one player (take Minecraft server, for example)

So my question is:

What should I read first? Where should I start?

Some tutorials, texts, guides would be nice. Remember: I'm a noob atmo

this looks like good start:

just google some things, during reading, that you have low knowledge at
