Setting Up Spring MVC 3.0

Why Spring MVC?

It’s been a while since I’ve done a lot with Java. I’ve been writing an Android app and see and interact with just enough Java not to forget what it looks like, but for the last couple of years, I’ve mainly worked in .NET with C#. Today, I started on actual development of my home automation server in earnest (will be added to github shortly). One of the main design goals of this home automation effort is to support affordable solutions and, toward that end, I am designing it to run on bare bones Linux machines, thus allowing old computers to be re-appropriated to run it.

This is the driving force in my choice of implementation tools. It needs to be runnable on Linux and Windows, and to have a small footprint. But, it also needs to support a true object oriented design paradigm and rich server side functionality. So, I will be dusting off my J2EE and using Spring MVC and Java for the server itself.

Setting up Spring MVC 3.0

I’ve been spoiled by developing principally in .NET over the last couple of years. In that world, any kind of project is usually a Visual Studio install and a plugin or NuGet package away. In the open source world of Spring and Java, it’s not quite as straightforward. My first step was, of course, a hello world app. I have plenty of Spring MVC/J2EE experience, but I was last developing with Spring when it was version 1.x, and we’re a few years removed and on 3.1, so I’m basically starting all over.

I already had Eclipse and Tomcat installed, and I set about finding an Eclipse plugin for creating a sample spring project or a tutorial on the same. I didn’t really find either. The most helpful thing I found, by far, was this blog post. If you take steps to satisfy the preconditions listed and follow the blog itself, you’ll be most of the way there.

I had to take two additional steps to get my new Spring “Hello World” project up and running. I had to get commons-logging.jar from the spring framework that I had downloaded and put it into my little app’s Web-INF\lib folder. I then had to do the same with jstl.jar from my Tomcat installation. Only after doing that was Hello World up and running.

Hopefully, this saves someone reading some time.
