Well as I said before in order to find the optimal solution we should know
some more details on your project and architecture....
what can I say in general is that Liferay portlets are basically JSP pages
so my suggestion is to develop your components as separate applications that
can also work stand-alone and then integrate them into Liferay.
Actually we followed two approaches in few past projects:
1. the simplest one, use a iFrame portlet to integrate into the portal our
clients as is, using iFrame parameters to communicate authentication and
other stuff. Consider that the iframe is a portlet itself and can be
extended as you wish in order to match your needs.
2. we developed GIS web clients for Liferay and used the standard portlet
protocol in order to pass over GET parameters to/from portal and other
portlets.
with the information I have I guess that I cannot be more useful than this.
What can I say in conclusion is just ... don't try to rebuild a new client
from scratch for Liferay but find a way to integrate it in the portal.
Hope my hints will be of some help for you.
Kind regards,
Alessio.
