Hi Guys

Does anybody know of a small scale example this sounds really interesting.

Thanks

Re: Pluggable architecture for wicket application

[Matt Pavlovich]

I extensively use Wicket+OSGi. Works great! Modular web applications are 
totally doable. Follow Martin's advice and wire in modules using the 
application hooks described.

The only hook provided by Wicket is org.apache.wicket.protocol.
http.WicketFilter#getClassLoader(). See org.apache.wicket.protocol.http.
ReloadingWicketFilter#reloadingClassLoader.

I know a Dutch company (or two) that use OSGi, I'm certain that one
uses Wicket + OSGi: educator.eu. The other, luminis.eu, does a lot of
work with OSGi, but might not use it in combination with Wicket. I
only have second hand knowledge about the combination, and it's
probably outdated.

Maybe someone from those companies is listening here and cares to comment.

Wicket doesn't manage class loaders. The web container (like Tomcat) deals
with this.
The only hook provided by Wicket is org.apache.wicket.protocol.
http.WicketFilter#getClassLoader(). See org.apache.wicket.protocol.http.
ReloadingWicketFilter#reloadingClassLoader.
