Grid portals, portlet frameworks, JSR 168 – compliant portlets
Grid portals are the most popular means for delivering user interfaces to Grids. Grid portals build upon the familiar Web portal model to offer virtual communities of users a single point of access to computational resources. The GridSphere Portal Framework is a Portlet JSR compliant portlet container that offers a set of base classes and tools for developing Web applications. The Grid Portlets web application, developed by the GridSphere Project, builds upon the core features in the GridSphere portal framework to provide developers with a framework for developing Grid portals.
