Subject Re: [OT] Wicket + OSGi
Date Fri, 09 Sep 2005 06:51:58 GMT
Very interesting article!

Did you consider moving the boilerplate code (which is most of the
code) outside to a separate bundle? A wicket bundle could easily
detect the installation of "wicket app" bundles, check a special resource
in the bundle and handle the web registration and other chores. In
this model, you only have to code the HelloWorld class in the
application bundle.

We call this the "extender" model and is used heavily in R4; for example
declarative services use this model. Features in R4 like
findEntryPaths, getResources, and loadClass are specifically added to
support this model.

The advantage is that it significantly reduces the coding for the
application as well as making it more robust and easier to integrate with
other apps (less knowledge in the app bundle).

Kind regards,

     Peter Kriens
