The eXo Platform Inc has introduced at JavaPolis its next Portal and ECM generation (both in their 2.0 alpha) that aims to use AJAX UI and Java backend (Portlet API and JCR) to simulate an true Web Operating System that fits the Enterprise needs. People can still create dynamic layout with an enhanced drag and drop but pages can also have a true desktop page a la Mac OS. Default and Mac skins are available, a Vista one is on the way. The entire ECM functionnalities are shown in a real File explorer that will make the ECM use much easier and a natural choice for people. Screenshots: Online demo: (login as exoadmin/exo) Download:
