I was just reading your blog and I realized that what your wrighting is so true! People should think more often about this subject because this is to important to forget. Btw your site is really hard to read on my blackberry. The screen looks very small and some words are placed outside of the borders. But besides that.. your blog is really top notch. Keep it up

I am looking for a similar solution too. I have experience of drupal, so I know how excellent plugin framework it has. you can do almost any thing.. infact most of parts of core drupal comes as core plugins. I too was thinking tht where is the java alternative.

Actually, OSGi already does this.

You can either (a) start up an OSGi engine inside a Servlet, thus deploying it as a war to an existing setup, or (b) bring up the OSGi servlet handler to slow you to install servlets (and URL prefixes) into an existing app.

Once up, in either case it’s fairly trivial to define services which enable your app to be built in a modular fashion. You can use vanilla OSGi services, the Eclipse extension registry, or combinations of both.

And if that doesn’t suit your exact needs, it’s simple enough to write a bundle that does handle it; for example, the declarative services and blueprint service take sone of these out if your hands and Into the realms of Spring-like functionality.
