Grab the software you need.

Here's a short list of some of the things that you will need to have to follow along with me.

An actual JDK:

Okay in order to develop with Java you need a Java Development Kit.

I usually run with OpenJDK but you can always choose the Sun JDK. If you go with OpenJDK get version 6. Simply because that's all I'm going to cover for now. At some time in the near future ditch 6 for 7 but for now stick with 6, it is more tested and has fewer bugs in the JVM.

A Java EE server:

You'll need one of these in order to run your crap, er, programs. I like JBoss and I usually prefer it for EE 5 development (RedHat just released a EE 6 server but I haven't had time to test drive it). However, here I'm going to be using Glassfish v 3.0.1. It is a EE 6 server, and version 2.1.1 is a very good EE 5 server, it's what we used at work for some time. I'm going to be using the Web Profile version as opposed to the full version. You can grab that if you want but very rarely do I venture into a need for RMI-IIOP (using the server to distribute logic to clients). Later down the road I may cover RMI but for now I'm just going to cover WebEE.

A database!!:

I like MySQL. PostgreSQL is nice too. I won't get into too many details, in my clique there are some very sided opinions about which is better than the other. Do not forget to pick up the JDBC driver from whoever you choose.

A JPA library:

Glassfish comes with EclipseLink which is an awesome JPA provider. It's also the one that I will be using here. Other than it is provided with Glassfish, I know a good deal of the JPA hints for this stack, so I'm really in my zone with this. If you went out and got JBoss, you'll need to go grab EclipseLink here.


Okay notepad is great and all but at some point you're going to need to ditch it because it sucks as a development tool. Basically at some point everything just blends together and you spend more time trying to parse your source code with your eyes or you spend more and more time with comments to keep everything in some sort of order.

At a bare minimum you need an editor that can do syntax highlighting, this prevents all that black and white running together. One that can do auto-indentation (saves you at least five or ten minutes every day per project), auto-brackets (saves at least two or three minutes per day), and has the terminal very close by is even better (like Kate or gedit.) A full blown-out IDE like Eclipse or NetBeans can shave off thirty minutes to an hour per day per project if you get down in there and learn to really use it.

I'm going to be using NetBeans here for most of the examples. One, because it was one of the first Java IDEs I ever used and two, it was the one my college professor told us to use. See this is why Microsoft is making a killing in our college's in the Untied States, most...(never mind getting off topic).

Go get Netbeans here.

That looks like a lot to go get. Just remember that you are setting up for whatever may come your way. Aside from having some sort of code repo software (like git or so) you're basically using the same tools that a professional would be using for this task.

Well I better get myself off to bed. Cheers!
