Magnolia CMS Module
headwire, one of our Integration partners, have produced an integration module for Magnolia and KonaKart that can be downloaded from their website. Magnolia is a content management system that powers the websites of government as well as leading Fortune 500 enterprises in more than 100 countries on all continents of the world. It is a leading Content Management System favored for its ease-of-use and availability under an Open Source license.
The headwire approach is to integrate the standard JSP / Struts based KonaKart store-front into Magnolia so this could be very appealing if you have already invested effort into customizing the KonaKart store-front. More details on the KonaKart/Magnolia integration module can be found on the headwire website.
