simject: Simple Dependency Injection

During my private studies on dependency injection (DI), dynamic proxy, remoting, Maven2 and JPA I started to create a small very simple dependency injection framework with some basic features.

It's not as powerful as Spring or similar frameworks but it helps me in my every day work, where I don't have a Java EE Server available.

I decided to make it available for every one - maybe someone can use it. Have a look: www.simject.org

Spring can be used perfectly well in any Java application, in or out of JEE.

Why not simply use and extend Guice? Externalized object wiring is highly overrated and usually not needed.

Hi William,

For sure Spring can do everything. The main purpose of simject is to keep it simple and to have a very small library.

Hi Robbie,

I only wanted to use Java SE Standard like the @Ressource annotation and the configuration should be external (e.g XML). That's why don't took Guice.

Why not picocontainer? (with nanocontainer)

Hi Peter,

I don't want to compete against PicoContainer or SpringFramework because they provide a lot more features than simject does. simject is a product of my private studies and I wanted to make it very simple.

But again if one is looking for simple dependecy injection with remoting and JPA support, let's try simject!

Regards, Simon

I have to ask... how about OSGi?

Simon Martinelli replied on Wed, 2008/08/20 - 2:55am in response to: James Ervin

OSGi is a great concept with dynamic component loading and versioning support.

simject does not address these features because I want to keep it extremly simple. It only provides simple dependency injection.

If you need all the OSGi features there are greate OSGi implementation like Equinox, Knopflerfish etc.
