Re: [Imbrium-developer] dynamic deployment of portlets

Maybe it's even better to do it the same way as a war file. We can give the
various components their own subdirectory within the archive, so we don't
have to mention them all in the deployment descriptor. This can avoid errors
in the deployment descriptor.
